[PATCH 0/2] amdgpu's drm_driver becomes const

[PATCH 0/2] amdgpu's drm_driver becomes const

[Luben Tuikov]

Hi Daniel,

These two patches follow up your latest
DRM work to make definitions of struct drm_driver
in DRM low-level drivers, constant, in amdgpu.

This set doesn't descend from my previous patch
"drm/amdgpu: Convert to using devm_drm_dev_alloc() (v2)",
since our branch doesn't have it, and I can see
that your const patches aren't in drm-next yet,
but they are based on my conversion patch.
Perhaps you can graft these two patches locally
and dispatch them via drm-next. (There'll be
a one-line conflict, namely the devm_drm_dev_alloc().)

Thanks and Regards,
Luben

[PATCH 1/2] drm/amdgpu/virt: fix handling of the atomic flag

[Luben Tuikov]

From: Alex Deucher <alexdeucher@gmail.com>

Use the per device drm driver feature flags rather than the
global one.  This way we can make the drm driver struct const.

Make the definition of struct drm_driver
a constant, to follow the latest developments
in the DRM layer.

Ah cool, thanks for doing this. I'll take your series here and include it
in mine and resend the entire pile.

freesync escaped from your internal tree, I dropped that when applying.
Plus I solved the conflict with drm_dev_alloc (it should be in drm-next
now sinc this morning, maybe good time to resync the internal tree to
avoid conflicts like this).

Otherwise looks a lot less work than I feared (after having wrangled
radeon to work), thanks for doing this.
