So follow the device id support by previous patch, this patch introduces device specific ops which points to device specific ops (e.g vfio ops). This allows the future drivers like virtio-mdev to implement its own device specific ops. Can you give an example about what ops might be required to support kernel mdev driver? I know you posted a link earlier, but putting a small example here can save time and avoid inconsistent understanding. Then it will help whether the proposed split makes sense or there is a possibility of redefining the callbacks to meet the both requirements. imo those callbacks fulfill some basic requirements when mediating a device... I put it in the cover letter. The link ishttps://lkml.org/lkml/2019/9/10/135 which abuses the current VFIO based mdev parent ops. Thanks So the main problem is the handling of userspace pointers vs. kernel space pointers. You still implement read/write/ioctl callbacks which is a subset of current parent_ops definition. In that regard is it better to introduce some helper to handle the pointer difference in mdev core, while still keeping the same set of parent ops (in whatever form suitable for both)? Pointers is one of the issues. And read/write/ioctl is designed for userspace API not kernel. Technically, we can use them for kernel but it would not be as simple and straightforward a set of device specific callbacks functions. The link above is just an example, e.g we can simply pass the vring address through a dedicated API instead of mandatory an offset of a file.

Mdev bus only support vfio driver right now, so it doesn't implement

one example is virtio-mdev[1] driver. This means we need to add device
id support in bus match method to pair the mdev device and mdev driver
correctly.
Sounds reasonable.
So this patch add id_table to mdev_driver and id for mdev parent, and
implement the match method for mdev bus.

[Intel-gfx] [PATCH] drm/i915: Fix S0ix/S3 suspend stress issue
During S0ix/S3 suspend stress test on Cometlake chromebook,
after few iterations we are seeing failure wrt PSR link CRC
Error and stress test stops. This S0ix test is failing only
when there is a CRC mismatch. In case of CRC mismatch, panel
generates IRQ_HD and whenever there is CRC mismatch, we are
disabling PSR2 in driver.
By not disabling PSR2 in driver and only by writing 1 to clear
sticky bit 0 in DPCD 0x2006 in panel,issue goes away.
Completed 2500 S0ix/S3 test cycles on multiple CML chromebooks.
As per EDP spec for CRC mismatch, nothing has been mentioned
explicitly for Source device, only by writing 1 to clear
sticky bit 0 in DPCD 0x2006 in sink is mentioned.

Umesh is right, the previous aging_tail needs to be taken into account. Basically we need to start from the previous aging_tail and continue incrementing by report_size till we catch up with the new hw_tail (at the previous report_size boundary, which gives the value of the new aging_tail). ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

So the main problem is the handling of userspace pointers vs.
kernel space pointers. You still implement read/write/ioctl
callbacks which is a subset of current parent_ops definition.
In that regard is it better to introduce some helper to handle
the pointer difference in mdev core, while still keeping the
same set of parent ops (in whatever form suitable for both)?

[Intel-gfx] [PATCH] drm/i915/dp: Fix DP MST error after unplugging TypeC cable
From: Srinivasan S
This patch avoids DP MST payload error message in dmesg, as it is trying
to read the payload from the disconnected DP MST device. After the unplug
the connector status is disconnected and we should not be looking for the
payload and hence remove the error and throw the warning.
This details can be found in:
https://bugs.freedesktop.org/show_bug.cgi?id=111632

[Intel-gfx] [CI 2/6] drm/i915/display/icl: Enable TRANSCODER PORT SYNC for tiled displays across separate ports
In case of tiled displays where different tiles are displayed across
different ports, we need to synchronize the transcoders involved.
This patch implements the transcoder port sync feature for
synchronizing one master transcoder with one or more slave
transcoders. This is only enbaled in slave transcoder
and the master transcoder is unaware that it is operating
in this mode.
This has been tested with tiled display connected to ICL.
v5:
* Add TRANSCODER_D case and MISSING_CASE (Maarten)
v4:
Rebase
v3:
* Check of DP_MST moved to atomic_check (Maarten)
v2:
* Do not use RMW, just write to the register in commit (Jani N)

[Intel-gfx] [CI 4/6] drm/i915/display/icl: Enable master-slaves in trans port sync
As per the display enable sequence, we need to follow the enable sequence
for slaves first with DP_TP_CTL set to Idle and configure the transcoder
port sync register to select the corersponding master, then follow the
enable sequence for master leaving DP_TP_CTL to idle.
At this point the transcoder port sync mode is configured and enabled
and the Vblanks of both ports are synchronized so then set DP_TP_CTL
for the slave and master to Normal and do post crtc enable updates.
v6:
* Modeset implies active_changed, remove one condition (Maarten)
v5:
* Fix checkpatch warning (Manasi)
v4:
* Reuse skl_commit_modeset_enables() hook (Maarten)
* Obtain slave crtc and states from master (Maarten)
v3:
* Rebase on drm-tip (Manasi)
v2:
* Create a icl_update_crtcs hook (Maarten, Danvet)
* This sequence only for CRTCs in trans port sync mode (Maarten)

[Intel-gfx] [CI 1/6] drm/i915/display/icl: Save Master transcoder in slave's crtc_state for Transcoder Port Sync
In case of tiled displays when the two tiles are sent across two CRTCs
over two separate DP SST connectors, we need a mechanism to synchronize
the two CRTCs and their corresponding transcoders.
So use the master-slave mode where there is one master corresponding
to last horizontal and vertical tile that needs to be genlocked with
all other slave tiles.
This patch identifies saves the master transcoder in all the slave
CRTC states. This is needed to select the master CRTC/transcoder
while configuring transcoder port sync for the corresponding slaves.
v4:
* Rebase
v3:
* Use master_tramscoder instead of master_crtc for valid
HW state readouts (Ville)
v2:
* Move this to intel_mode_set_pipe_config(Jani N, Ville)
* Use slave_bitmask to save associated slaves in master crtc state (Ville)

Okay will change commit message and description to:
drm/i915/tgl/pll: Set update_active_dpll
Commit 24a7bfe0c2d7 ("drm/i915: Keep the TypeC port mode fixed when the
port is active") added this new hook while in parallel TGL upstream was
happening and this was missed.
Without this driver will crash when TC DDI is added and driver is
preparing to do a full modeset.
Sounds good?

Well we can do that on top or in Imre series not planing to address
this in here.

@Clint
Looks like git send-email don't like "," in the name and replaces your
email address to tay...@freedesktop.org so I'm going to replace your
signed-off-by to "Clinton A Taylor " or do
you prefer something else?

The rebase of https://patchwork.freedesktop.org/patch/261142/ looks
correct, so
Reviewed-by: Matt Roper
but it looks like we'll also need an update to IGT before we merge this,
otherwise it will break CI testing for kms_plane and kms_plane_scaling.
IGT needs this new format added to formats[] in lib/igt_color_encoding.c
so that lookup_fourcc() won't return failures.

It is used in intel_ddi.c, the user is added in "drm/i915/tgl: Add dkl
phy programming sequences" I guess I can move this patch right before
that one.

Re: [Intel-gfx] [PATCH v2] drm/i915/guc: Enable guc logging on guc log relay write
On Mon, Sep 16, 2019 at 03:50:18PM -0700, Robert M. Fosha wrote:
Creating and opening the GuC log relay file enables and starts
the relay potentially before the caller is ready to consume logs.
Change the behavior so that relay starts only on an explicit call
to the write function (with a value of '1'). Other values flush
the log relay as before.
v2: Style changes and fix typos. Add guc_log_relay_stop()
function. (Daniele)

Our assumption that the we can ask the HW to lock the SFC even if not
currently in use does not match the HW commitment. The expectation from
the HW is that SW will not try to lock the SFC if the engine is not
using it and if we do that the behavior is undefined; on ICL the HW
ends up to returning the ack and ignoring our lock request, but this is
not guaranteed and we shouldn't expect it going forward.

What's our plan if this *ERROR* is ever triggered?
If it remains do nothing and check the logs on death, then it remains
just a debug splat. If there is a plan to actually do something to
handle the error, do it!
-Chris
AFAIU the only thing we can do is escalate to full gpu reset. However,
the probability of this failing should be next to non-existent (only one
engine can use the SFC at any time so there is no lock contention), so
I'm not convinced the fallback is worth the effort. The error is still
useful IMO to catch unexpected behavior on new platforms, as it happened
in this case with the media team reporting seeing this message on gen12
with the previous behavior. This said, I'm happy to add the extra logic
if you believe it is worth it.
We've see this message on every icl run!
-Chris
I've never noticed it, which tests are hitting it? My understanding from
what the HW team said is that on ICL the ack will always come back (even
if it is not part of the "official" SW/HW interface) and the HW tweak
that stops that is a gen12 change. Something else might be wrong is this
is firing off in our ICL CI, also because I don't think we have any test
case that actually uses the SFC, do we?
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_6911/fi-icl-u2/igt@i915_selftest@live_hangcheck.html
All icl, live_hangcheck or live_reset, for as long as I can remember.
-Chris
Thanks. I'm going to check with the HW team to see what their
recommended timeout value is, in case ours is too short. It could also
be that even on ICL the ack is not always returned if the SFC is not
actually in use.

Fwiw, we say the maximum size for the haswell context is 70270, which even expanding for prefetch is well inside the next page boundary of 73728. Furthermore, no DMAR faults. The coincidence may be a timing artifact of the iommu indirection? Or just a mere coincidence. -Chris ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

That may have been a mistake... Something else to bear in mind about why this is showing up now, is that the enabling of iommu on these machines. It's the last instruction in the context image...

I re-sent this through trybot to see if I could get a valid result for
cml-h, but now cml-h appears to have completely disappeared from the
machine list:
https://intel-gfx-ci.01.org/tree/drm-tip/Trybot_5035/index.html
and wasn't even listed as missing in the "participating hosts" part of
the report. It's also missing from the general results page at:
https://intel-gfx-ci.01.org/tree/drm-tip/index.html
Anyway, based on the cml-s results it appears this patch does do what we
hoped and fixes the PCH detection. Lucas, do you feel comfortable
giving it a r-b so we can apply it or do you want to wait until the
cml-h CI machine comes back?

[Intel-gfx] [PATCH] drm/i915: Extend Haswell GT1 PSMI workaround to all
A few times in CI, we have detected a GPU hang on our Haswell GT2
systems with the characteristic IPEHR of 0x780c. When the PSMI w/a
was first introducted, it was applied to all Haswell, but later on we
found an erratum that supposedly restricted the issue to GT1 and so
constrained it only be applied on GT1. That may have been a mistake...
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111692
Fixes: 167bc759e823 ("drm/i915: Restrict PSMI context load w/a to Haswell GT1")

This should be 16 only for DDR4, and 32 otherwise - however, it's not
actually used anywhere, so it doesn't matter, but a comment (in case it
needs to be used in the future) would be good.

AFAIU the only thing we can do is escalate to full gpu reset. However,
the probability of this failing should be next to non-existent (only one
engine can use the SFC at any time so there is no lock contention), so
I'm not convinced the fallback is worth the effort. The error is still
useful IMO to catch unexpected behavior on new platforms, as it happened
in this case with the media team reporting seeing this message on gen12
with the previous behavior. This said, I'm happy to add the extra logic
if you believe it is worth it.
We've see this message on every icl run!

I've never noticed it, which tests are hitting it? My understanding from
what the HW team said is that on ICL the ack will always come back (even
if it is not part of the "official" SW/HW interface) and the HW tweak
that stops that is a gen12 change. Something else might be wrong is this
is firing off in our ICL CI, also because I don't think we have any test
case that actually uses the SFC, do we?

Since we've dropped the lock around this check, the intent is to use the
pin as a guarantee that the vma cannot be changed. What we actually want
here, for clarity, is vma->cache_level.

We can't add more vma to the object, as there are no more refs to the
object. The challenge is in dropping the links. In the end it makes no
difference, it's an unlocked compare before the spinlock (and ugly
loop).

It's a counter for the number of unique binds as opposed to callers
merely acquiring the pages prior to binding; so that we can balance
vma_unbind_pages() which is called once

AFAIU the only thing we can do is escalate to full gpu reset. However,
the probability of this failing should be next to non-existent (only one
engine can use the SFC at any time so there is no lock contention), so
I'm not convinced the fallback is worth the effort. The error is still
useful IMO to catch unexpected behavior on new platforms, as it happened
in this case with the media team reporting seeing this message on gen12
with the previous behavior. This said, I'm happy to add the extra logic
if you believe it is worth it.

Our assumption that the we can ask the HW to lock the SFC even if not

ends up to returning the ack and ignoring our lock request, but this is
not guaranteed and we shouldn't expect it going forward.

How do we race here? Are we not in complete control of the engine at
this point so the status of this engine using SFC or not should be
static, no?
The hang detection might be due to a long non-preemptable batch, in
which case there is in theory a chance for the batch to release the SFC
while we try to lock it. The chance is incredibly small though, so am I
being too paranoid?

But the function checked whether SFC wasn't in use and bailed out
early - so is this comment relevant? (I understand it is true against
the specs just wondering about our exact code.)
Same rationale as the above, if the engine relased the SFC while we were
locking it, the locking might have been rejected, but on ICL we still
get the ack.

Here we can't rely on the return code from gen11_lock_sfc and have to
read the register ourselves? I guess it depends on my question about
the race comment.
In addition to this I now see that gen11_reset_engines does not use
the return value from gen11_lock_sfc when deciding which engines it
needs to unlock. Should we change that as well?
Paranoia here as well, in case something went wrong with the locking I'd
like to be sure the unlocking can still be performed independently so we
can recover. e.g. the locking might have succeeded after we hit the
timeout in gen11_lock_sfc , in which case the return from that function
won't reflect the status of the HW.
Thanks,
Daniele

The aging tail is always pointing to the boundary of a report whereas the hw_tail is advancing in 64 byte increments. The innermost OA_TAKEN is returning the number of bytes between the hw_tail and the aging_tail. The modulo is getting the size of the partial report (if any). The outermost OA_TAKEN is subtracting the size of partial report from the hw_tail to get a hw_tail that points to the boundary of the last full report. The value of hw_tail would be the same as from the deleted line of code above this line. Looks like aging_tail should not be needed (it is complicating the expression and is not there in the original expression). All we need is a "circular modulus". For example would the following work? original expression assumes all report sizes are powers of 2 and hence does not need a reference (like aging_tail) to rounddown the hw_tail. if (hw_tail < report_size) hw_tail += OA_BUFFER_SIZE; Assuming that this condition is detecting a report split across the OA buffer boundary, the above check will not catch the split in cases where there are multiple reports generated before we read the hw_tail. hw_tail = rounddown(hw_tail, report_size); Another way (if we want to avoid the division) would be to maintain a cached copy of hw_tail in SW which is successively (and circularly) incremented by report_size till it catches up with hw_tail read from HW. But probably the first method above is simpler. aging_tail is a cached copy of the hw_tail that advances only in report size increments.

But if you strongly feel against this, I can switch this to writing 0 directly.

[Intel-gfx] [PATCH v3] drm/i915: Lock signaler timeline while navigating
As we need to take a walk back along the signaler timeline to find the
fence before upon which we want to wait, we need to lock that timeline
to prevent it being modified as we walk. Similarly, we also need to
acquire a reference to the earlier fence while it still exists!
Though we lack the correct locking today, we are saved by the
overarching struct_mutex -- but that protection is being removed.
v2: Tvrtko made me realise I was being lax and using annotations to
ignore the AB-BA deadlock from the timeline overlap. As it would be
possible to construct a second request that was using a semaphore from the
same timeline as ourselves, we could quite easily end up in a situation
where we deadlocked in our mutex waits. Avoid that by using a trylock
and falling back to a normal dma-fence await if contended.

We are getting more and more these nested ones and it will become
unmanageable to remember which ones, why and on what paths. Perhaps we
need a comment next to the member in the structure definition?
The timeline mutex is held for request construction and retire; entry
and exit of the timeline->requests. Since we have a request, it should
be holding its rq->timeline->mutex; is that what you wish documented?
Similarly that signal->timeline != rq->timeline.
GEM_BUG_ON(signal->timeline == rq->timeline);
lockdep_assert_held(&rq->timeline->mutex);
Yeah that helps.

+ }
+ mutex_unlock(&tl->mutex);
+ if (!fence)
Can it be no fence when it was obtained under the mutex?
Yes. The previous fence may have been retired and so removed from the
tl->requests before we acquire the mutex. It should not be freed while
it is still in the list, i.e. dma_fence_get_rcu() should never return
NULL.
I did not worry about the list_is_first check, just about
dma_fence_get_rcu. At least I'm happy that one is safe and v2 is even
better in this respect.

Tvrtko

Yes the asserts make it obvious now why the nested annotation is needed.

[Intel-gfx] [PATCH v2] drm/i915: Lock signaler timeline while navigating
As we need to take a walk back along the signaler timeline to find the
fence before upon which we want to wait, we need to lock that timeline
to prevent it being modified as we walk. Similarly, we also need to
acquire a reference to the earlier fence while it still exists!
Though we lack the correct locking today, we are saved by the
overarching struct_mutex -- but that protection is being removed.

Add the lockdep assert and GEM_BUG_ON to note the overlapping timelines.

The timeline mutex is held for request construction and retire; entry
and exit of the timeline->requests. Since we have a request, it should
be holding its rq->timeline->mutex; is that what you wish documented?
Similarly that signal->timeline != rq->timeline.
GEM_BUG_ON(signal->timeline == rq->timeline);

Yes. The previous fence may have been retired and so removed from the
tl->requests before we acquire the mutex. It should not be freed while
it is still in the list, i.e. dma_fence_get_rcu() should never return
NULL.

Re: [Intel-gfx] [PATCH] drm/i915: Verify the engine after acquiring the active.lock
On 16/09/2019 12:38, Chris Wilson wrote:
When using virtual engines, the rq->engine is not stable until we hold
the engine->active.lock (as the virtual engine may be exchanged with the
sibling). Since commit 22b7a426bbe1 ("drm/i915/execlists: Preempt-to-busy")
we may retire a request concurrently with resubmitting it to HW, we need
to be extra careful to verify we are holding the correct lock for the
request's active list. This is similar to the issue we saw with
rescheduling the virtual requests, see sched_lock_engine().

Re: [Intel-gfx] [PATCH] drm/i915: Lock signaler timeline while navigating
On 17/09/2019 08:43, Chris Wilson wrote:
As we need to take a walk back along the signaler timeline to find the
fence before upon which we want to wait, we need to lock that timeline
to prevent it being modified as we walk. Similarly, we also need to
acquire a reference to the earlier fence while it still exists!
Though we lack the correct locking today, we are saved by the
overarching struct_mutex -- but that protection is being removed.

My stance was that with clear ~0, user should be notified.
But I guess on this level of tooling, you should be free
to do the useless read.

We don't want to duplicate the entire function. Pretty much the
whole point of having the sa_info struct is to make this parametrized.

[Intel-gfx] [PATCH i-g-t] i915/gem_mmap_gtt: Replace forked-mmaped tests with a lighter variant
Introduce a new 2-process fork test that is bound to a single cpu to
exercise contention during pagefaults. This is a much lighter variant of
the all-cpus test intended to be viable even on the legendary frozen
lakes of molasses.

[Intel-gfx] [v2][PATCH 0/3] adding gamma state checker for icl+ platforms
In this patch series, added state checker to validate gamma lut values for icelake+ platforms. It's extension of the patch series https://patchwork.freedesktop.org/patch/328246/?series=58039 which enabled the basic infrastructure and state checker for legacy platforms.

[Intel-gfx] [v2][PATCH 2/3] drm/i915/display: Extract icl_read_luts()
For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode, add hw lut creation for this mode.
This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl feature.
v2: -readout code for multisegmented gamma has to come
up with some intermediate entries that aren't preserved
in hardware (Jani N)
-linear interpolation (Ville)
-moved common code to check gamma_enable to specific funcs,
since icl doesn't support that

Now we're back to enforcing DMA_BIDI, which works nicely around the
locking pain, but apparently upsets the arm-soc folks who want to
control
this better.

No, the contract between importer and exporter stays exactly the same it
is currently as long as you don't switch to dynamic dma-buf handling.

So you still break the contract between importer and exporter, except not
for anything that's run in intel-gfx-ci so all is good?
The other issue with "we solve this with caching the mapping": Currently
map/un
