[PATCH xf86-video-amdgpu 1/9] Use drmmode_crtc_scanout_free in drmmode_fini

[PATCH xf86-video-amdgpu 1/9] Use drmmode_crtc_scanout_free in drmmode_fini

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer@amd.com>

We were leaking drmmode_crtc->scanout_damage, which caused trouble on
server reset. Fixes server reset with active separate scanout pixmaps.

(Cherry picked from radeon commit 0c29deb5a97d9a57e994cc0053c49ddf7aca6ecb)

[PATCH xf86-video-amdgpu 7/9] Call drmmode_set_desired_modes from a WindowExposures hook

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer@amd.com>

This is the earliest opportunity where the root window contents are
guaranteed to be initialized, and prevents drmmode_set_mode_major from
getting called before drmmode_set_desired_modes via AMDGPUUnblank ->
drmmode_crtc_dpms. Also, in contrast to the BlockHandler hook, this is
called when running Xorg with -pogo.

Fixes intermittently showing garbage on server startup or after server
reset.

As a bonus, this avoids trouble due to higher layers (e.g. the tigervnc
Xorg module) calling AMDGPUBlockHandler_oneshot repeatedly even after
we set pScreen->BlockHandler = AMDGPUBlockHandler_KMS.

[PATCH xf86-video-amdgpu 8/9] Move DPMS check from amdgpu_scanout_do_update to amdgpu_scanout_flip

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer@amd.com>

When amdgpu_scanout_do_update is called from
drmmode_crtc_scanout_update, drmmode_crtc->pending_dpms_mode may still
be != DPMSModeOn, e.g. during server startup.

Fixes intermittently showing garbage with TearFree enabled.

(Ported from radeon commit cc9d6b7db9c2078be1e530a64af6d517c6a42024)

[PATCH xf86-video-amdgpu 9/9] Don't call amdgpu_glamor_flush in drmmode_copy_fb

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer@amd.com>

AMDGPUWindowExposures_oneshot takes care of it.
