drm/radeon: avoid bogus "vram limit (0) must be a power of 2" warning

2022-07-07T19:55:44+00:00

I was getting the following message on boot on Linux 5.19-rc5:
        radeon 0000:01:05.0: vram limit (0) must be a power of 2
(I didn't use any radeon.vramlimit commandline parameter).

This is caused by
commit 8c2d34eb53b9 ("drm/radeon: use kernel is_power_of_2 rather than local version")
which removed radeon_check_pot_argument() and converted its users to
is_power_of_2(). The two functions differ in its handling of 0, which is
the default value of radeon_vram_limit: radeon_check_pot_argument()
"incorrectly" considered it a power of 2, while is_power_of_2() does not.

An appropriate conditional silences the warning message.

It is not necessary to add a similar test to other callers of
is_power_of_2() in radeon_device.c. The matching commit in amdgpu:
commit 761175078466 ("drm/amdgpu: use kernel is_power_of_2 rather than local version")
is unaffected by this bug.

Tested on Radeon HD 3200.

Not ccing stable, this is not serious enough.

drm/radeon: Drop CONFIG_BACKLIGHT_CLASS_DEVICE ifdefs

2022-06-21T22:17:24+00:00

The DRM_RADEON Kconfig code contains:

	select BACKLIGHT_CLASS_DEVICE

So the condition these ifdefs test for is always true, drop them.

drm: Drop drm_framebuffer.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_frambuffer.h, so don't include it.
Avoids useless rebuilds of the entire universe when
touching drm_framebuffer.h.

Quite a few placs do currently depend on drm_framebuffer.h without
actually including it directly. All of those need to be fixed
up.

v2: Fix up msm some more
v2: Deal with ingenic and shmobile as well

drm/radeon: Initialize fences array entries in radeon_sa_bo_next_hole

2022-06-08T15:41:09+00:00

Similar to the handling of amdgpu_sa_bo_next_hole in commit 6a15f3ff19a8
("drm/amdgpu: Initialize fences array entries in amdgpu_sa_bo_next_hole"),
we thought a patch might be needed here as well.

The entries were only initialized once in radeon_sa_bo_new. If a fence
wasn't signalled yet in the first radeon_sa_bo_next_hole call, but then
got signalled before a later radeon_sa_bo_next_hole call, it could
destroy the fence but leave its pointer in the array, resulting in
use-after-free in radeon_sa_bo_new.

drm/radeon: integer overflow in radeon_mode_dumb_create()

2022-06-08T15:40:41+00:00

Similar to the handling of amdgpu_mode_dumb_create in commit 54ef0b5461c0
("drm/amdgpu: integer overflow in amdgpu_mode_dumb_create()"),
we thought a patch might be needed here as well.

args->size is a u64.  arg->pitch and args->height are u32.  The
multiplication will overflow instead of using the high 32 bits as
intended.
