| * drm/nouveau: Turn off CRTCs on driver unloadLukas Wunner2016-06-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nouveau leaks a runtime pm ref if at least one CRTC is enabled on unload. The ref is taken by nouveau_crtc_set_config() and held as long as a CRTC is in use. nv04_display_destroy() should solve this by turning off all CRTCs, but (1) nv50_display_destroy() doesn't do the same and (2) it's broken since commit d6bf2f370703 ("drm/nouveau: run mode_config destructor before destroying internal display state") because the crtc structs are torn down by drm_mode_config_cleanup() before being turned off. Also, there's no locking. Move the code to turn off all CRTCs from nv04_display_destroy() to nouveau_display_destroy() so that it's called for both nv04 and nv50 and before drm_mode_config_cleanup(). Use drm_crtc_force_disable_all() helper to save on code and have proper locking.

* drm/nouveau/display: Enable vblank irqs after display engine is on again.Mario Kleiner2016-02-171-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | In the display resume path, move the calls to drm_vblank_on() after the point when the display engine is running again. Since changes were made to drm_update_vblank_count() in Linux 4.4+ to emulate hw vblank counters via vblank timestamping, the function drm_vblank_on() now needs working high precision vblank timestamping and therefore working scanout position queries at time of call. These don't work before the display engine gets restarted, causing miscalculation of vblank counter increments and thereby large forward jumps in vblank count at display resume. These jumps can cause client hangs on resume, or desktop hangs in the case of composited desktops. Fix this Linux 4.4 regression by reordering calls accordingly.

Therefore that functionality got semi-disabled in commit af4870e406126b7ac0ae7c7ce5751f25ebe60f28 Author: Mario Kleiner <mario.kleiner.de@gmail.com> Date: Tue May 13 00:42:08 2014 +0200 drm/nouveau/kms/nv04-nv40: fix pageflip events via special case. Unfortunately that hack got uprooted in commit cc1ef118fc099295ae6aabbacc8af94d8d8885eb Author: Thierry Reding <treding@nvidia.com> Date: Wed Aug 12 17:00:31 2015 +0200 drm/irq: Make pipe unsigned and name consistent Triggering a warning when trying to sample the vblank timestamp for a non-existing pipe. There's a few ways to fix this: - Open-code the old behaviour, which just enshrines this slight breakage of the userspace ABI. - Revert Mario's commit and again inflict broken timestamps, again not pretty. - Fix this for real by delaying the pageflip TS until the next vblank interrupt, thereby making it accurate. This patch implements the third option. Since having a page flip interrupt that happens when the pageflip gets armed and not when it completes in the next vblank seems to be fairly common (older i915 hw works very similarly) create a new helper to arm vblank events for such drivers. v2 (Mario Kleiner): - Fix function prototypes in drmP.h - Add missing vblank_put() for pageflip completion without pageflip event. - Initialize sequence number for queued pageflip event to avoid trouble in drm_handle_vblank_events(). - Remove dead code and spelling fix. v3 (Mario Kleiner): - Add a signed-off-by and cc stable tag per Ilja's advice. v4 (Thierry Reding): - Fix kerneldoc typo, discovered by Michel Dänzer - Rearrange tags and changelog Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=106431 Cc: Thierry Reding <treding@nvidia.com> Cc: Mario Kleiner <mario.kleiner.de@gmail.com> Acked-by: Ben Skeggs <bskeggs@redhat.com> Cc: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Reviewed-by: Mario Kleiner <mario.kleiner.de@gmail.com> Cc: stable@vger.kernel.org # v4.3 Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* | drm: Stop using linedur_ns and pixeldur_ns for vblank timestampsVille Syrjälä2015-09-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | linedur_ns, and especially pixeldur_ns are becoming rather inaccurate to be used for the vblank timestamp correction. With 4k@60 the pixel duration is already below 2ns, so the amount of error due to the truncation to nanoseconds is introducing quite a bit of error. We can avoid such problems if we instead calculate the timestamp delta_ns directly from the dislay timings, avoiding the use of these intermediate truncated values.

The vast majority of callers used the embedded _init() interfaces. - No longer storing constructor arguments (and the data returned from nvkm) inside nvif_object, it's more or less unused and just wastes memory.

* make RAM device optionalAlexandre Courbot2015-04-141-1/+8
| | | | | | | | | | | | | | | Having a RAM device does not make sense for chips like GK20A which have no dedicated video memory. The dummy RAM device that we used so far works as a temporary band-aid, but in the longer term it is desirable for the driver to be able to work without any kind of VRAM. This patch adds a few conditionals in places where a RAM device was assumed to be present and allows some more objects to be allocated from the TT domain, allowing Nouveau to handle GPUs for which pfb->ram == NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've read INVBL as "invalid backlight" and got mightly confused. The #defines are already fairly long and we can afford to extend them a bit more without resulting in ugly code all over. I'm not sure how useful the complicated bitmask return value of these functions really are since no one checks them. But for now let's keep things as is.

* | | drm/nouveau: make sure display hardware is reinitialised on runtime resumeBen Skeggs2014-10-021-12/+11
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | Linus commit 05c63c2ff23a80b654d6c088ac3ba21628db0173 modified the runtime suspend/resume paths to skip over display-related tasks to avoid locking issues on resume. Unfortunately, this resulted in the display hardware being left in a partially initialised state, preventing subsequent modesets from completing. This commit unifies the (many) suspend/resume paths, bringing back display (and fbcon) handling in the runtime paths. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
