[Bug 71051] Cannot suspend with radeon drivers.
by bugzilla-daemon＠bugzilla.kernel.org 20 Sep '14

20 Sep '14

https://bugzilla.kernel.org/show_bug.cgi?id=71051 --- Comment #13 from Hin-Tak Leung <htl10(a)users.sourceforge.net> --- (In reply to Michel Dänzer from comment #12) > (In reply to Hin-Tak Leung from comment #11) > > photo of the double-pointer corruption > > Looks like you're using an old version of xf86-video-modesetting, or another > generic driver which doesn't correctly handle 128x128 hardware cursors. > Please use the radeon driver from a current version of xf86-video-ati; with > glamor enabled, that also provides X-Video support. Thanks for the hints! Bringing drv-ati,drv-modesetting,glamor up gives me the correct cursor, and I get X-Video after bring mesa (and llvm) up - from up-to-date fedora 20 to the not-yet-alpha fedora 21-ish. The mouse cursor totally disappeared after GUI login in the first reboot (and I had to use vt2 to reboot the system again) and video playback showed very strange colors - almost B/W-ish - after the first X restart, but both wierdness seems to be gone in later reboots, so far. So as far as I am concerned, I just need attachment 150801 going upstream, and possibly the hibernate cik_ring_test/radeon_dp_link_train_cr error issue looked at. FWIW, I tested attachment 150801 against 3.16.2 (or rather, adapted fedora's 3.16.2-200 to include the patch). -- You are receiving this mail because: You are watching the assignee of the bug.

[PATCH v2] drm/exynos: switch to universal plane API
by Andrzej Hajda 19 Sep '14

19 Sep '14

The patch replaces legacy functions drm_plane_init() / drm_crtc_init() with drm_universal_plane_init() and drm_crtc_init_with_planes(). It allows to replace fake primary plane with the real one. Additionally the patch leaves cleanup of crtcs to core, this way planes and crtcs are cleaned in correct order.

[GIT PULL] drm/exynos: exynos-drm-next
by inki.dae＠samsung.com 19 Sep '14

19 Sep '14

Hi Dave, Sorry for late. This pull request includes some enhancements for Exynos drm, new feature supports, cleanups and fixups like below, - Consider low power transmission for drm mipi dsi module, and also add non-continuous clock mode support for Exynos mipi dsi driver. - Add Exynos3250 SoC support. - Enhance and clean up ipp framework and fimc driver. - Update to use component match support and fix up de-initialization order. - Remove a direct mmap interface and relevant stuff specific to Exynos drm, use drm generic mmap interface instead. And we will remove the specific interface from userspace library, libdrm soon. - Use universal plane which allows to replace fake primary plane with the real one. - Some code cleanups and fixups. Please kindly let me know if there is any problem.

[PATCH] drm/exynos: switch to universal plane API
by Andrzej Hajda 19 Sep '14

19 Sep '14

The patch replaces legacy functions drm_plane_init() / drm_crtc_init() with drm_universal_plane_init() and drm_crtc_init_with_planes(). It allows to replace fake primary plane with the real one.

As a side effect it should solve fb refcounting issues reported by me and Daniel Drake.
