2017-02-09drm/nouveau/nv1a,nv1f/disp: fix memory clock rate retrievalIlia Mirkin
commit 24bf7ae359b8cca165bb30742d2b1c03a1eb23af upstream. Based on the xf86-video-nv code, NFORCE (NV1A) and NFORCE2 (NV1F) have a different way of retrieving clocks. See the nv_hw.c:nForceUpdateArbitrationSettings function in the original code for how these clocks were accessed.

2017-01-09drm/nouveau/fifo/gf100-: protect channel preempt with subdev mutexBen Skeggs
commit b27add13f500469127afdf011dbcc9c649e16e54 upstream. This avoids an issue that occurs when we're attempting to preempt multiple channels simultaneously. HW seems to ignore preempt requests while it's still processing a previous one, which, well, makes sense. Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel piglit runs on (at least) GM107.

2016-08-20drm/nouveau/fbcon: fix font width not divisible by 8Mikulas Patocka
commit 28668f43b8e421634e1623f72a879812288dd06b upstream. The patch f045f459d925 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459d925 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459d925 was backported.

2016-03-03drm/nouveau/display: Enable vblank irqs after display engine is on again.Mario Kleiner
commit ff683df7bf34f90766a50c7e7454e219aef2710e upstream. 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.

2015-12-04drm/nouveau: Fix pre-nv50 pageflip events (v4)Daniel Vetter
Apparently pre-nv50 pageflip events happen before the actual vblank period. 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>

There's a few places where we need to access a GPC register from ucode, but outside of the falcon's io address space. To do this we need to calculate the offset based on which GPC we're executing on. This used to be done manually, but we've since found a "base" offset that can be added by the hardware. To use this, an extra bit needs to be set in the register address, which is what this macro achieves. There should be no functional change from this commit.
