[git pull] drm/vmwgfx fixes for 5.12-rc8

[Dave Airlie]

Hi Linus,

Back from holidays and this was in the cracks (Zack forgot to cc
Daniel/lists), I've just piled it onto drm fixes.

It contains two regression fixes for vmwgfx, one due to a refactor
which meant locks were being used before initialisation, and the other
in fixing up some warnings from the core when destroying pinned
buffers.

Dave.

[git pull] drm fixes for 5.12-rc7

[Dave Airlie]

Hey Linus,

Was relatively quiet this week, but still a few pulls came in, pretty
much small fixes across the board, a couple of regression fixes in the
amdgpu/radeon code, msm has a few minor fixes across the board, a
panel regression fix also.

I'm out all next week, so Daniel will do any last minute fixes for the
final release, assuming things stick to schedule. I'll be back for the
merge window but might towards the end of the first week before I get
my MR lined up.

Dave.

[Dave Airlie]

Hi Linus,

Things have settled down in time for Easter, a random smattering of
small fixes across a few drivers. I'm guessing though there might be
some i915 and misc fixes out there I haven't gotten yet, but since
today is a public holiday here, I'm sending this early so I can have
the day off, I'll see if more requests come in and decide what to do
with them later.

Dave.

[Dave Airlie]

Hi Linus,

As expected last week things were overly quiet so this week things
seem to have caught up. It still isn't too major.

msm and amdgpu lead the size here, the msm fixes are pretty varied
across the driver, the amdgpu one is mostly the S0ix fixes with some
other minor ones. Otherwise there are a few i915 fixes and one each
for nouveau, etnaviv and rcar-du.

Dave.

[git pull] drm fixes for 5.12-rc3

[Dave Airlie]

Hi Linus,

Regular fixes for rc3. The i915 pull was based on the rc1 tag so I
just cherry-picked the single fix from there to avoid it. The misc and
amd trees seem to be on okay bases.

It's a bunch of fixes across the tree, amdgpu has most of them a few
ttm fixes around qxl, and nouveau.

Dave.

drm-fixes-2021-03-12-1:
drm fixes for 5.12-rc3

core:

- Fix ttm page pool accounting.

fbdev:
- Fix oops in drm_fbdev_cleanup()

shmem:
- Assorted fixes for shmem helpers.

qxl:
- unpin qxl bos created as pinned when freeing them,
  and make ttm only warn once on this behavior.
- Zero head.surface_id correctly in qxl.

atyfb:
- Use LCD management for atyfb on PPC_MAC.

meson:
- Shutdown kms poll helper in meson correctly.

nouveau:

Hi Linus,

More may show up but this is what I have at this staged. These are
based on the commit in your tree where the swapfile issue is fixed,
and neither of the merged trees are in the bad area.

Otherwise just a single nouveau regression fix, and a bunch of amdgpu fixes.

Dave.

Hi Linus,

Hope power/internet are back on fully!

This is fixes but I missed msm-next pull last week. It's been in
drm-next anyways so shouldn't be a problem.

Otherwise it's a selection of i915, amdgpu and misc fixes, one TTM
memory leak, nothing really major stands out otherwise.

[git pull] drm fixes for 5.11-rc7

[Dave Airlie]

Hi Linus,

Fixes for rc7, bit bigger than I'd like at this stage, but most of the
i915 stuff and some amdgpu is destined for staging and I'd rather not
hold it up, the i915 changes also pulled in a few precusor code
movement patches to make things cleaner, but nothing seems that
horrible, and I've checked over all of it.

Otherwise there is a nouveau dma-api warning regression, and a ttm
page allocation warning fix,
and some fixes for a bridge chip,

Dave.

drm-fixes-2021-02-05-1:

[git pull] drm fixes for 5.11-rc6

[Dave Airlie]

Hey Linus,

Weekly fixes for graphics, nothing too major, nouveau has a few
regression fixes for various fallout from header changes previously,
vc4 has two fixes, two amdgpu, and a smattering of i915 fixes.

All seems on course for a quieter rc7, fingers crossed.

Dave.

I think the fix for this is in drm-misc-next, Maarten can you send me
a -next PR to fix this?

[git pull] drm nouveau ampere modesetting support

[Dave Airlie]

Hi Linus,

As mentioned in the previous pull, Ben has requested if we can include
Ampere modesetting support under fixes, it's for new GPUs and
shouldn't affect existing hardware. It's a bit bigger than just adding
a PCI ID, and I'm fine if you think we should hold it off until later.

Dave.

[git pull] drm fixes for 5.11-rc4

[Dave Airlie]

Hey Linus,

Back to mostly regular scheduling for me. Big thanks to Daniel for
stepping into my duties for the last few turns.

Regular fixes for rc4, a bunch of fixes across i915, amdgpu and
nouveau here, along with a couple of TTM fixes, and dma-buf and one
core pageflip/modifier interaction fix. One notable i915 fix is a HSW
GT1 regression fix that has been outstanding for quite a while.
(Thanks to Matt Turner for kicking Intel into getting it fixed).

Ben Skeggs has asked about the possibility of pulling nvidia ampere
basic display support into fixes as new hardware with nothing outside
touched, I'll queue up a separate pull after this one and you can
decide if it's appropriate.

Dave.

[git pull] drm fixes for 5.10 final

[Dave Airlie]

Hi Linus,

Last week of fixes, just amdgpu and i915 collections. We had a i915
regression reported by HJ Lu reported this morning, and this contains
a fix for that he has tested.

There are a fair few other fixes, but they are spread across the two
drivers, and all fairly self contained.

I'm going to send you out drm-next for next week in a few hours as I'm
going on holidays until next Friday, I likely won't be checking email
too closely, but Daniel should be available for any emergency.

Dave.

[git pull] drm fixes for 5.10-rc7

[Dave Airlie]

Hi Linus,

This week's regular fixes. i915 has fixes for a few races,
use-after-free, gpu hangs,
tegra just has some minor fixes that I didn't see much point in
hanging on to. The
nouveau fix is for all pre-nv50 cards and was reported a few times.
Otherwise it's
just some amdgpu, and a few misc fixes.

Regards,
Dave.

[git pull] drm fixes for 5.10-rc6

[Dave Airlie]

Hi Linus,

Bit of a delay as fd.o anongit was acting up a bit today, hopefully it
stays up this time. Unfortunately this has a bit of thanksgiving
stuffing in it, as it a bit larger (at least the vc4 patches) than I
like at this point in time.

The main thing is it has a bunch of regressions fixes for reports in
the last  couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.

The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.

Hopefully you can merge this between turkey slices, and next week
should be quieter.

Dave.

Oh this patch is a handful, I can see why people stall out here.

I'm going to be annoying maintainer and see if you can clean this up a
bit in advance
of this patch.

1) move the callbacks out of struct intel_panel.backlight into a separate struct
and use const static object tables, having fn ptrs and data co-located
in a struct
isn't great.

strcut intel_panel_backlight_funcs {

};
struct intel_panel {
struct {
struct intel_panel_backlight_funcs *funcs;
};
};

type of thing.

I think you could reuse the backlight funcs struct for the pwm stuff
as well. (maybe with an assert on hz_to_pwm for the old hooks).

2) change the apis to pass 0 down in a separate patch, this modifies a
bunch of apis to pass in an extra level parameter, do that
first in a separate patch that doesn't change anything but hands 0
down the chain. Then switch over in another patch.

3) One comment in passing below.

The change here confused me since it no longer calls lpt_get_backlight
in this path, the commit msg might explain this, but it didn't explain
is so I could figure out if that was a mistake or intentional.

[git pull] drm fixes for v5.10-rc5

[Dave Airlie]

Hi Linus,

Weekly fixes pull. This contains some fixes for sun4i/dw-hdmi probing,
then amdgpu enables arcturus hw without experimental flag and two
other fixes and a group of i915 fixes.

It also has a backported from next fix for the warn on reported in
ast/drm_gem_vram_helper code in the rc1 pull request thread. The rc4
PR has a thread which initially looked to be the same problem, but I'm
going to chase that up next week a bit more as I don't think the
bisect landed anywhere useful.

Dave.

https://patchwork.freedesktop.org/patch/401559/

should fix it.

We had a report in the rc1 thread but it got lost in the nouveau stuff
as well, I've cc that reporter as well.

please test.

I'd be mildly surprised if it's that commit, since it just refactors
what looks to me to be two identical code pieces into one instance
(within the scope of me screwing that up, but reading it I can't see
it).

I'll dig into this today.

I would like to say when you sent this, there was patches on the
mailing lists with Kirill cc'ed, a pull request outstanding to me on
the mailing list from Ben, with the patches reviewed in it.

Maybe you weren't cc'ed on it, but stuff has certainly happened, in
the timeframe, and I was keeping track of it from falling down a hole.

_nothing_ is a lot more a reflection on your research than the ongoing
process, there was some delays here and maybe we need to communicate
when we are flat out dealing with other more urgent tasks that pay the
actual wages.

Nearly didn't send you a PR this week at all, but a few things
trickled in over the day, not a huge amount here, some i915, amdgpu

next week.

[git pull] drm fixes for 5.10-rc3

[Dave Airlie]

Hey Linus,

It's Friday here so that means another installment of drm fixes to
distract you from the counting process.

Changes all over the place, the amdgpu changes contain support for a
new GPU that is close to current one already in the tree (Green
Sardine) so it shouldn't have much side effects.

Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
have around the usual smattering of fixes, fonts got constified, and
vc4/panfrost has some minor fixes. All in all a fairly regular rc3.

I think we have an outstanding nouveau regression, but the author is
looking into the fix, so should be here next week.

I now return you to counting.
Dave.

had a chance to validate it,

Apparently I lied, and I only built my merged tree on x86

Hi Linus,

Karol found two last minute nouveau fixes, they both fix crashes, the
TTM one follows what other drivers do already, and the other is for
bailing on load on unrecognised chipsets.

Thanks,

Hi Linus,

Daniel queued these up last week and I took a long weekend so didn't
get them out, but fixing the OOB access on get font seems like
something we should land and it's cc'ed stable as well. The other big
change is a partial revert for a regression on android on the clcd
fbdev driver, and one other docs fix.

Dave.

[git pull] drm amdgpu + vmwgfx fixes for 5.9-rc8

[Dave Airlie]

Hi Linus,

Just dequeuing these a bit early as the AMD ones are bit larger than
I'd prefer, but Alex missed last week so it's a double set of fixes.
The larger ones are just register header fixes for the new chips that
were just introduced in rc1 along with some new PCI IDs for new hw.
Otherwise it is usual fixes.

The vmwgfx fix was due to some testing I was doing and found we
weren't booting properly, vmware had the fix internally so hurried it
out to me.

I'm off tomorrow and Monday but I'll be around in case there are any
major issues with this, or if I get set of intel or misc fixes come
in.

Dave.

Is this possible in drm-next now (it's 5.9.0-rc5 based)?

or will I need to get a stable shared git tree that goes into drm-next
and you send to Linus early in the MR?

[git pull] drm fixes for 5.9-rc7

[Dave Airlie]

Hi Linus,

Due to the dax merge fail in rc6, this has two backmerges, Intel
pulled in a later point in time to fix their CI systems, I also pulled
in an earlier point to fix my local builds.

Otherwise fairly quiet, a couple of i915 fixes, one dma-buf fix, one
vc4 and two sun4i changes.

I realised I missed the sun4i + vc4 fixes in the tag itself. They are below.

Dave.

vc4:
- fill asoc card owner

sun4i:
- program secondary CSC correctly.

drm-fixes-2020-09-25:

dma-buf:
- Single null pointer deref fix for dma-buf

i915:
- Fix selftest reference to stack data out of scope
- Fix GVT null pointer dereference

[git pull] drm fixes for 5.9-rc6

[Dave Airlie]

Hi Linus,

A bunch of small fixes, some of the i915 ones have been out for a
while and got better commit msg explaining some better reasoning
behind them. (hopefully this trend continues). Otherwise there a few
AMD related ones mostly small, one radeon PLL regression fix and a
bunch of small mediatek fixes.

I'm going to be offline for a couple of days in a few hours time, so
if anything is wrong let Daniel know as well.

Dave.

Hi Linus,

Regular fixes, not much a major amount. One thing though is Laurent
fixed some Kconfig issues, and I'm carrying the rapidio kconfig change
so the drm one for xlnx driver works. He hadn't got a response from
rapidio maintainers.

Otherwise, virtio, sun4i, tve200, ingenic have some fixes, one audio
fix for i915 and a core docs fix.

DAve.

i915:

virtio:
- Fix double free in virtio.
- Fix virtio unblank.
- Remove output->enabled from virtio, as it should use crtc_state.

sun4i:
- Add missing put_device in sun4i, and other fixes.
- Handle sun4i alpha on lowest plane correctly.

tv200:
- Fix tve200 enable/disable.

The i915 reverts are going to be a bit of a conflict mess for next, so
I decided to dequeue them now, along with some msm fixes for a ring
corruption issue, that Rob sent over the weekend.

I'm going to pull in the reverts this week I think, Intel are changing
some part of their patchflows to me, but the 5.10 queue had to revert
some stuff in this area for other reasons, so I'd like to sanely get
those into 5.9 as well.

[git pull] drm fixes for 5.9-rc3

[Dave Airlie]

Hey Linus,

As expected a bit of an rc3 uptick, amdgpu and msm are the main ones,
one msm patch was from the merge window, but had dependencies and we
dropped it until the other tree had landed. Otherwise it's a couple of
fixes for core, and etnaviv, and single i915, exynos, omap fixes.

I'm still tracking the Sandybridge gpu relocations issue, if we don't
see much movement I might just queue up the reverts. I'll talk to
Daniel next week once he's back from holidays.

Dave.

I'm inclined to agree with Laurent here.

Patches submitted as GPL-v2 with DCO lines and author names/companies
should be fine to be squashed and rearranged,
as long as the DCO and Authorship is kept somewhere in the new patch
that is applied.

Review is more important here.

Dave.

I think there's been some discussion about reverting that change for
other reasons, but it's quite likely the culprit.

Maybe we can push for a revert sooner, (cc'ing more of i915 team).

[git pull] drm fixes for 5.9-rc1

[Dave Airlie]

Hi Linus,

This is the fixes pull for 5.9-rc1. I had some fixes from the misc
fixes tree come on a later base than drm-next was on, so I had to
backmerge 5.8 into this to make things work for me and CI. However it
totally messed up the diffstat so I didn't bother including it. The
changelog looks fine.

This has a few vmwgfx regression fixes we hit from the merge window
(one in TTM), it also has a bunch of amdgpu fixes along with a
scattering everywhere else.

I'm not working for next few days, but I'll be around and have some
time if anything comes up, but hopefully this is good enough for rc1,
and any pulls after this can wait for rc2.

Dave.

Ben might just have imported them directly, so SPDX tags might need to
be sent upstream and see if they accept them.

I should say I did a test merge yesterday, but you likely pulled more trees,

https://lore.kernel.org/dri-devel/20200806115140.6aa46...@canb.auug.org.au/T/#t

[git pull] drm fixes for 5.8-rc8 (part 2)

[Dave Airlie]

Hi Linus,

As mentioned previously this contains the nouveau regression fix,
amdgpu had 3 fixes outstanding as well, one revert, an info leak and
use after free. The use after free is a bit trickier than I'd like,
and I've personally gone over it to confirm I'm happy that it is doing
what it says.

Let me know if any issues with any, happy to respin if necessary.
Dave.

Can you test the drm fixes pull I just sent to Linus

Otherwise we are awaiting a fix from James for one other issue, should
be here today/tomorrow.

[git pull] drm fixes for 5.8-rc8

[Dave Airlie]

Hi Linus,

I'm sending this out a bit early, just to give you a chance to reject
it or help decide on an rc8.

The nouveau fixes missed the last pull by a few hours, and we had a
few arm driver/panel/bridge fixes come in. This is possibly a bit more
than I'm comfortable sending at this stage, but I've looked at each
patch, the core + nouveau patches fix regressions, and the arm related
ones are all around screens turning on and working, and are mostly
trivial patches, the line count is mostly in comments.

If you feel this is too much I'm happy to respin with the
core/drm_fb_helper and nouveau fixes. we have one outstanding nouveau
regression fix, that I'll follow this up with in the next day or so
once Ben and James get it reviewed.

Dave.

This is possibly a bit

[git pull] drm fixes for 5.8-rc6

[Dave Airlie]

Hi Linus,

Weekly fixes pull, big bigger than I'd normally like, but they are
fairly scattered and small individually. The vmwgfx one is a black
screen regression, otherwise the largest is an MST encoder fix for
amdgpu which results in a WARN in some cases, and a scattering of i915
fixes.

I'm tracking two regressions at the moment that hopefully we get
nailed down this week for rc7.

Dave.

[git pull] drm fixes for 5.8-rc5

[Dave Airlie]

Hi Linus,

I've been off most of the week, but some fixes have piled up. Seems a
bit busier than last week, but they are pretty spread out across a
bunch of drivers, none of them seem that big or worried me too much.

Regards,
Dave.

Sorry I misdirected what you said a bit, and I did misinterpret as
Australia also has it's own indigenous slavery issues,

I was trying to stop the "white slavery" is a thing crew from turning
up on this.

Apologies for accidentally implying something what you hadn't said.

As I said "it means nothing if you've never interacted with gambling
culture," red black in the context of the trees as zero meaning other
than as a name to find it on the internet, Search for that name enough
and you will undoubtedly be getting ads for online roulette sites
within hours, if you have a problem gambling past, this might not be
the desired effect you'd want.

The reasons something was named a particular thing can and will be
different from what a societal context for them means now, and I
believe it's more important to worry about current societal contexts
than legacy historical namings. I'm not seriously suggesting we rename
red-black trees, but if someone who had a problematic gambling
background had issues with them I'd definitely be open for considering
it.

I'd totally submit that red/black trees while in no way racist, are a
horrible indirection, as it means nothing if you've never interacted
with gambling culture, (and maybe James Bond movies).

left/right trees make naturally more sense and translate into more
languages, so yes I think removal of color naming is a good thing even
for non-racist reasonings.

I don't totally agree on that, because like the CoC discussion, people
need concrete examples. People need reasons, saying simply "be
inclusive" doesn't work.

You say "be inclusive" people don't think about it, they just go "I'm
inclusive" and proceed, never questioning what it means to be
inclusive, they normalise inclusivity to their self image and within
their lives where they might never confront anything like this.

I don't doubt we get the American/Ottoman/Barbery coast people and the
correct answer to those people is to tell them to examine why they
suddenly care about Barbery slavery now when they have never even
heard or worried about it before. Why haven't they submitted patches
removing slavery terminology from the kernel before?

Dave.

The racial issues are wider than that, and even wider again I'm sure,
but in 2020 this is as good a place to start as any, and the trigger
as that sentence says was in 2020, there was a reckoning about it
mainly due to people of African descent. That trigger has had flow on
effects in other countries, but I'm not sure that sentence in any way
diminishes that, it's merely an introduction to why this change is
happening now.

As for the non-black slavery, others have never pointed this out
before in 30 years of master/slave terminology? surely if white
slavery was as big a problem, they be as supportive of this, even more
so. It speaks volumes that I've never heard white slavery as a problem
once in 30 years, but now I'm hearing about it a few times, and
somehow as an excuse not to support this.

[git pull] drm fixes for 5.8-rc4

[Dave Airlie]

Hey Linus,

Pretty usual rc4 pull, two usual amdgpu, i915 pulls, and some misc arm
driver fixes.
The bigger bit is including the asm sources for some GPU shaders that
were contained in the i915 driver, otherwise it's pretty much business
as usual.

What timezone are the conferences being held in? It impacts on what I

[git pull] drm fixes for v5.8-rc3

[Dave Airlie]

Hi Linus,

Usual rc3 pickup, lots of little fixes all over, The core VT
registration regression fix is probably the largest, otherwise ttm,
amdgpu and tegra are the bulk, with some minor driver fixes. No i915
pull this week which may or may not mean I get 2x of it next week,
we'll see how it goes.

Regards,
Dave.

My bad, my local builds passed, as I had made the change but forgot

Pushed out a new head with it in it now.

Hi Linus,

rc2 fixes, just i915 and amd here, i915 has some workaround movement
so they get applied at the right times, and a timeslicing fix, along
with some display fixes. AMD has a few display floating point fix and
a devcgroup fix for amdkfd.

  (+ 1 dependency patch)
- Fixes into TypeC register programming and interrupt storm detecting
- Disable DIP on MST ports with the transcoder clock still on
- Avoid missing GT workarounds at reset for HSW and older gens
- Fix for unwinding multiple requests missing force restore
- Fix encoder type check for DDI vswing sequence
- Build warning fixes

Can you document the rules all drivers should be following then,
because from here it looks to get refactored every version of i915,
and it would be nice if we could all aim for the same set of things
roughly. We've already had enough problems with amdgpu vs i915 vs
everyone else with fences, if this stops that in the future then I'd
rather we have that than just some unwritten rules per driver and
untestable.

[git pull] drm fixes for 5.7-rc1 (updated pull)

[Dave Airlie]

Hi Linus,

This is the update of the pull I sent earlier today, it's got a couple
of more fixes along with the i915 fixes. One sun4i fix and a connector
hotplug race The ast fix is for a regression in 5.6, and as mentioned
previously one of the i915 ones fixes an oops reported by dhowells.

definitely taking tomorrow off now :-)

Regards,
Dave.

[git pull] drm i915 fixes for rc1

[Dave Airlie]

Hi Linus,

dhowells reported an oops, and the i915 team tracked it down to a
missing fix that didn't have correct tags, they've pulled it in along
with two other fixes.

I might have some more fixes for rc1, but I might not, taking the day
off tomorrow, so probably won't be in a hurry to process anything new
unless something urgent lands.

Thanks,
Dave.

[git pull] drm msm next for 5.8-rc1

[Dave Airlie]

Hi Linus,

This should be the final feature pull for drm for rc1. This tree has
been in next for a couple of weeks, but Rob missed an arm32 build
issue, so I was awaiting the tree with a patch reverted. The tree was
also based on an 5.7-rc5 tree so I didn't want to futz around with
backmerging just for this, so I'm sending it from a topic branch based
on v5.7.

Dave.

[git pull] drm next fixes for 5.7-rc1

[Dave Airlie]

Hey Linus,

This are the fixes from last week for the stuff merged in the merge
window. It got a bunch of nouveau fixes for HDA audio on some new
GPUs, some i915 and some amdpgu fixes.

I've got another pull request with Rob's msm next stuff in it I'll
send along after this, it was in -next all along, but it needed a
revert before I merged it, and it also was on a different base, so
I'll sent a separate pull from my fixes branch to avoid me having to
backmerge anything here yet.

Dave.

Yes sounds like my experience.

I spent time on the tides and it was a revert pretty much of the
commit in next, I just missed the header include line.

I also realised I'd likely mismerged earlier when fixing this up, I'm
going to have to put more time into merge fixing up, I'm still not
always happy with my methods of figuring out what the correct answer
is.

Cool, thanks for redoing it, since this was definitely one of the more
conflicty ones I've had in a while.

Dave.

[git pull] drm fixes for 5.7 final (apologies release)

[Dave Airlie]

Hey,

Apologies for previous PR, I did build it locally, I just don't build
EXPERT kernels, I expect if I ever get a new builder I should add a
few more configs to my list.

I've just dropped the i915 PR from this completely, I'm sure when they
wake up they'll be able to tell us what we are missing due to mistakes
made.

Dave.

I did drop the ball in one way, I see sfr reported it broken this morning

I normally expect stuff coming from Intel has been through their CI,
even their fixes tree generally gets pushed through that system before
I get it, and it usually catches these things.

I might have to push back on intel fixes this late in the day, as
maybe the land on next and cherry-pick to fixes model has made them a
bit lax on how much stuff goes through CI.

I've just drop the whole i915 fixes from the tree and will resend with
it removed.

Dave.

I thought I'd dropped the ball completely. but I see it's a selftest
failure, I must not have selftests built in my config here, I don't do
exhaustive builds randconfig

This has also been built by Intel, but I'm assuming they missed their
selftest bits as well.

I'll revert that and resend.

Sorry for the noise. I'll add self tests to my builds here for future ones.

That doesn't make sense though,

if you write the full english words out for something it'll be long
but easier to say over the phone,
if you use shortened kernel abbreviations it will be short but you'd
have to read out every letter.

To take an example:
this would read pretty well on the phone, maybe params could be parameters
amdgpu_atombios_get_leakage_vddc_based_on_leakage_params

vddc would be a stumbler.

try saying O_CREAT over the phone to someone not steeped in UNIX folklore.

No it doesn't, I think you missed the pci in API name.

The initial behaviour doesn't use the pci version of the API, the
replacement did, and the fix used the drm wrapper around the pci one.

So this patch isn't necessary now that I've fixed it the other way,

Thanks,
Dave.

I reproduced with 5.7.0-rc7, and tried this patch on top in the same
VM doing the same thing.

with this patch I no longer see the lockdep trace.

[git pull] drm fixes for v5.7-rc7

[Dave Airlie]

Hi Linus,

Things seemed to have quieten down, though no i915 pull (I even gave
them an extra 12 hours in case they were late). The amdgpu floating
point fix is probably the largest, but it just moves some code around
to it doesn't do fpu stuff outside the fpu boundaries. Otherwise it's
just a couple of vmwgfx fixes (maintainer change) and two etnaviv
fixes.

Dave.

Just updated a rawhide VM to the Fedora 5.7.0-rc5 kernel, did some

I also have another concern from a legal standpoint I'd rather not
review the ioctl part of this. I'd probably request under DRI
developers abstain as well.

This is a Windows kernel API being smashed into a Linux driver. I
don't want to be tainted by knowledge of an API that I've no idea of
the legal status of derived works. (it this all covered patent wise
under OIN?)

I don't want to ever be accused of designing a Linux kernel API with
illgotten D3DKMT knowledge, I feel tainting myself with knowledge of a
properietary API might cause derived work issues.

Okay I've had some caffiene and absorbed some more of this.

This is a driver that connects a binary blob interface in the Windows
kernel drivers to a binary blob that you run inside a Linux guest.
It's a binary transport between two binary pieces. Personally this
holds little of interest to me, I can see why it might be nice to have
this upstream, but I don't forsee any other Linux distributor ever
enabling it or having to ship it, it's purely a WSL2 pipe. I'm not
saying I'd be happy to see this in the tree, since I don't see the
value of maintaining it upstream, but it probably should just exists
in a drivers/hyperv type area.

Having said that, I hit one stumbling block:
"Further, at this time there are no presentation integration. "

If we upstream this driver as-is into some hyperv specific place, and
you decide to add presentation integration this is more than likely
going to mean you will want to interact with dma-bufs and dma-fences.
If the driver is hidden away in a hyperv place it's likely we won't
even notice that feature landing until it's too late.

I would like to see a coherent plan for presentation support (not
code, just an architectural diagram), because I think when you
contemplate how that works it will change the picture of how this
driver looks and intergrates into the rest of the Linux graphics
ecosystem.

As-is I'd rather this didn't land under my purview, since I don't see
the value this adds to the Linux ecosystem at all, and I think it's
important when putting a burden on upstream that you provide some
value.

Hi Jeffery,

Just wondering what the userspace/testing plans for this driver.

This introduces a new user facing API for a device without pointers to
users or tests for that API.

Although this isn't a graphics driver, and Greg will likely merge
anything to the kernel you throw at him, I do wonder how to validate
the uapi from a security perspective. It's always interesting when
someone wraps a DMA engine with user ioctls, and without enough
information to decide if the DMA engine is secure against userspace
misprogramming it.

Also if we don't understand the programming API on board the device,
we can't tell if the "core" on the device are able to reprogram the
device engines either.

Figuring this out is difficult at the best of times, it helps if there
is access to the complete device documentation or user space side
drivers in order to faciliate this.

The other area I mention is testing the uAPI, how do you envisage
regression testing and long term sustainability of the uAPI?

Thanks,
Dave.

We would rather drivers using a feature that has requirements on
correct userspace implementations of the feature have a userspace that
is open source and auditable.

Fencing is tricky, cross-device fencing is really tricky, and having
the ability for a closed userspace component to mess up other people's
drivers, think i915 shared with closed habana userspace and shared
fences, decreases ability to debug things.

Ideally we wouldn't offer users known untested/broken scenarios, so
yes we'd prefer that drivers that intend to expose a userspace fencing
api around dma-fence would adhere to the rules of the gpu drivers.

I'm not say you have to drop using dma-fence, but if you move towards
cross-device stuff I believe other drivers would be correct in
refusing to interact with fences from here.

Dave.
