[PATCH v6 0/6] Raspberry PI 4 V3D enablement

[PATCH v6 0/6] Raspberry PI 4 V3D enablement

[Peter Robinson]

This is a follow up from my v4 patchset. The power management pieces have
been split out to a separate independent set of patches by Stefan [1]. This
version 5 of the DRM patches are independent and given the V3D driver has
been upstream for some time the two patches to enable it in defconfigs can 
be taken at anytime independent of the enablement for the Raspberry Pi 4.

I've tested this using mesa 22.0.x and Wayland/Gnome on Fedora 36, it's 
more or less stable with basic testing.

Changes since v5:
- Update the DT compatible to match the others that were updated
- Adjust the Kconfig help text
- Add review tags

Changes since v4:
- Fixes for device tree and bindings
- Split out the power management changes into an independent set
- Rebase to 5.18
- Individual changes in patches

[PATCH v6 1/6] dt-bindings: gpu: v3d: Add BCM2711's compatible

[Peter Robinson]

BCM2711, Raspberry Pi 4's SoC, contains a V3D core. So add its specific
compatible to the bindings.

[PATCH v6 2/6] drm/v3d: Get rid of pm code

[Peter Robinson]

Runtime PM doesn't seem to work correctly on this driver. On top of
that, commit 8b6864e3e138 ("drm/v3d/v3d_drv: Remove unused static
variable 'v3d_v3d_pm_ops'") hints that it most likely never did as the
driver's PM ops were not hooked-up.

So, in order to support regular operation with V3D on BCM2711 (Raspberry
Pi 4), get rid of the PM code. PM will be reinstated once we figure out
the underlying issues.

I've spent some time trying to get PM working properly on RPi4, but I
haven´t gotten good results yet, and all attempts ended up disabling the
auto suspend option somehow. Keeping in mind how long this has been
unresolved, I agree to clean it now as we continue to investigate the
issue.

I can take the last 3 patches through the Broadcom ARM SoC pull request, 
but the first three should probably go via the DRM tree unless you want 
me to merge them all?

I can merge the first 3 patches through the drm-misc tree. Can I get
an ack from you for those ?

The changes are independent so there's no need for an immutable branch
or any kind of cross tree coordination.

Hi Javier,

I'm not sure if you're suggesting here to apply the entire series as it
is now.

I'm not able to have a functional kernel from arm defconfig, only for
arm64. I'd like to have this issue clarified before merge this serie. I
tried multi_v7_defconfig on raspbian 32-bits and got a kernel panic.
Things work better when using downstream bcm2711_defconfig.

If you have an idea of what is going on, please, let me know. I can try
again and I'll be okay on merging it. Otherwise, let's wait for more
inputs to have a better picture of the situation.

Thanks,

Melissa

No. I suggested that could just apply the first 3 patches that were related
to DRM, not the last 3 three since Florian will pick those.

Can you please share for info? For example your boot log when it panics,
maybe that could shed some light on what's going on.

Of course I don't plan to push patches that are known to cause issues.

I mentioned that could help merging the DRM changes if needed before
you sent your bug report.

Hi Javier,

Thanks for waiting a little.

Stefan guided me to the missing part and I'm okay on this serie.

If there's any r-b missing for drm/v3d, you can add mine:

But if you prefer that I applied them, just let me know.

If you can apply them that's even better since you are more involved
with this driver. I was just trying to be helpful and that's why I
volunteered to push, to prevent this effort to get stalled :)

Hi Peter,

I was able to check and run some tests on arm64, and it seems ok. But I
was not successful on bringing it up for arm using multi_v7_defconfig +
device_tree=bcm2711-rpi-4-b.dtb.

How can I check this path?

Btw, using the config from rpi downstream kernel works nicely for arm
(on my side)

for Raspberry Pi 4 you also need to enable CONFIG_ARM_LPAE, which is not 
enabled in multi_v7_defconfig.
