[Nouveau] nouveau module not loading
Hi! I have a rather decent notebook (Toshiba Satellite P105-S9722) with Nvidia GeForce Go 7900 GS video card. I installed latest debian system with kernel 3.13-1-amd64 on it, but unfortunately nouveau driver doesn't work.

[Nouveau] Help me, Nouveau list, you're my only hope...
I hope I'm writing to people who can help me. If not you, then I have a serious inconvenience and am going to be at a complete loss for where to turn. Let me explain my setup. I have an HTPC with a GeForce GT620. It is connected to a Denon AVR-1913 via HDMI, because that does all the switching for my entertainment system then out to an LG flat-panel 55-inch TV via HDMI. Everything was working beautifully until it wasn't. All of a sudden, I simply cannot get the receiver to recognize the video signal from the video card. The display on the front does not switch to HDMI, and the audio will not switch away from analog. And all that the display says is DENON. Now the video card works fine. It is hooked up directly to the TV via DVI->HDMI, and the TV has no problem with that signal. Tonight I bypassed the receiver altogether, and the video went out via HDMI to the TV fine as well, even though the TV's input list had the HDMI input grayed. When I selected it, it worked fine. So that got me thinking it was the input on the receiver or something else on the receiver. No such luck. A Blu-Ray player works fine through the same input, and my MacBook Pro works fine through the same input. If I am diagnosing things properly, the receiver is not accepting the mode the HDMI out of the GeForce card is setting, even though xrandr shows the same mode being set on both the DVI out and the HDMI out. Can you help me debug the problem? Thanks in advance,Will___ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau

The formatting here is somewhat weird. From a brief look I couldn't find
any indication that nouveau deviates from the standard coding style, so
this should be:
} else if (...) {

The commit message makes it sound like SW isn't needed since gk20a
"lacks any display hardware". In that case the comment here doesn't make
much sense.

Perhaps this (and the comment in the code) should mention a unit. In this case it's 0x40 words. Also, I think using a decimal number would read easier here and in the comment.

Perhaps I'm being paranoid, but this loop now depends on the frequency
of the various clocks involved and therefore might break at some point
if the frequencies get sufficiently high.
So a slightly safer implementation would use a proper timeout using a
combination of msecs_to_jiffies(), time_before() and usleep_range(),
like so:
timeout = jiffies + msecs_to_jiffies(...);
while (time_before(jiffies, timeout)) {
command = nv_rd32(...) & 0x3f;
if (command == 0)
break;
usleep_range(...);
}
if (time_after(jiffies, timeout))
nv_warn(...);
This assumes that there's some known timeout after which the ringmaster
is expected to have acked the interrupt. On that note, I wonder if the
warning is accurate here: it's my understanding that writing 0x2 to the
register does acknowledge the interrupt, so the ringmaster does in fact
"clear" it rather than "acknowledge" it, doesn't it?
Although now that I mention it I seem to remember that this write is
actually sending a command to the ring master and perhaps waiting for
the register to return to 0 is indeed waiting for an ACK of sorts. Maybe
adding a comment or so describing what this sequence does would be
appropriate here?

I don't think this variable is really necessary since you only use the

The calls to nvc0_bar_init_vm() are somewhat confusing in my opinion. It
is hard to see from the invocation what these numbers mean and therefore
distinguish which parameter is which.
Perhaps a slightly more readable way would be to pass in a pointer to a
structure as second parameter instead of the index into an array. So
it'd look somewhat like this:
if (has_bar3) {
ret = nvc0_bar_init_vm(priv, &priv->bar[0], 3);
...
}
...
ret = nvc0_bar_init_vm(priv, &priv->bar[1], 1);
...
Unfortunately that would require a new type to be created for the bar[]
structures, so it'd be slightly more intrusive.

Perhaps a better solution would be to add a "flags" or "features" field to struct nouveau_device along with feature bits such as HAS_CALIBRATION or similar. That way we don't have to touch this code for every new future Tegra chip. Unless perhaps if there's a reason to expect things to change in newer generations.

[Nouveau] PROM vbios fetching issues
Hello, One of my GPU (GK107/NVE7) fails to properly fetch its vbios from PROM at boot time but, if I blacklist the module and load it myself later on, it always succeeds. To make things weirder, the same card works great on another computer. Here is the relevant code in Nouveau to fetch the vbios from PROM: http://code.woboq.org/linux/linux/drivers/gpu/drm/nouveau/core/subdev/bios/base.c.html#nouveau_bios_shadow_prom The only solution I found to this problem is to try up to 16 times in a row to fetch the vbios using PROM. If the 16 tries yield a bad signature or checksum, I just give up and let it try other techniques. Here is the patch[1]. With this hack in place, the number of retries needed to be able to correctly fetch the vbios ranges from 0 to 13. I see no consistency in this. I tried reading the vbios 32 bits by 32 bits (instead of 8 by 8), disabling local IRQs and generating more activity on the PCIe port before fetching (and making sure the value read is always the same), all solutions yielded no improvement. It could be a brownout problem but this would be the only manifestation of this problem. Moreover, some cards are known to have problems with PROM[2] so mine is definitely not the only one. I'm at a loss here, should we wait on anything before reading from PROM? The mmiotrace I have doesn't seem to suggest we should :s I wonder if you have had this issue before and what the nvkm does here.

I understand that both patches suffer from the race condition you were trying to avoid in the first place, but an always on/off monitor is a bit of a handicap :) Alternatively/in addition, I would welcome hints on how to make Nouveau survive power-cycling the monitor (e.g. by running a command over SSH to reset the display). The current behaviour is: [On, displaying] ↓ Turn off [Off] ↓ Turn on [Booting] ⋮ [OSD: No input; shutting down] ⋮ [Standby] Of course, feel free to suggest proper fixes, docs to read, and/or patches to test.

[Nouveau] [PATCH 08/12] drm/nouveau/graph: enable when using external firmware
nvc0_graph_ctor() would only let the graphics engine be enabled if its
oclass has a proper microcode linked to it. This prevents GR from being
enabled at all on chips that rely exclusively on external firmware, even
though such a use-case is valid.
Relax the conditions enabling the GR engine to also include the case
where an external firmware has also been loaded.

[Nouveau] [PATCH 10/12] drm/nouveau/graph: add GK20A support
Add a GR device for GK20A based on NVE4, with the correct classes
definitions (GK20A's 3D class is 0xa297).
Most of the NVE4 code can be used on GK20A, so make relevant bits of
NVE4 available to other chips as well.

[Nouveau] [PATCH 04/12] drm/nouveau/bar/nvc0: support chips without BAR3
Adapt the NVC0 BAR driver to make it able to support chips that do not
expose a BAR3. When this happens, BAR1 is then used for USERD mapping
and the BAR alloc() functions is disabled, making GPU objects unable
to rely on BAR for data access and falling back to PRAMIN.

[Nouveau] [PATCH 00/12] drm/nouveau: support for GK20A, cont'd
Hi everyone, Here is the second batch of patches to add GK20A support to Nouveau. This time we are adding the actual chip support, and this series brings the driver to a point where a slightly-tweaked Mesa successfully runs shaders and renders triangles on GBM! Many thanks to Thierry Reding and the people on the #nouveau IRC channel for their help without which we would not have reached this milestone. A few lines of hacks (not included here) are still needed to deal with cached mappings triggering external aborts and CPU/GPU memory coherency issues, but I hope to understand and address these issues next. Most of the changes below have already been seen (and sometimes reviewed) in an earlier patchset. What has been added is proper PGRAPH support (still needing an external firmware and mostly reusing NVE4's code) as well as a better RAM implementation. How to represent and manage VRAM has been the hardest part to deal with, since GK20A shares the system memory with the CPU without any kind of partition. I have tried various approaches (included some in which no RAM object ever gets instanciated) and finally decided to go for one using DMA-contiguous memory allocations and relying on BAR mappings for kernel access and exposure to user-space, as it fits better with existing code and keeps us safe from most of the CPU/GPU memory coherency issues (at the cost of some performance). Looking forward to your review of these few patches! :) Cheers, Alex.

[Nouveau] [PATCH 03/12] drm/nouveau/bar: only ioremap BAR3 if it exists
Some chips that use system memory exclusively (e.g. GK20A) do not
expose 2 BAR regions. For them only BAR1 exists, and it should be used
for USERD mapping. Do not map BAR3 if its resource does not exist.
