| | * drm/nouveau/therm: implement support for temperature alarmsMartin Peres2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, we only boost the fan speed to the maximum and auto-mode when hitting the FAN_BOOST threshold and halt the computer when it reaches the shutdown temperature. The downclock and critical thresholds do nothing. On nv43:50 and nva3+, temperature is polled because of the limited hardware. I'll improve the nva3+ situation by implementing alarm management in PDAEMON whenever I can but polling once every second shouldn't be such a problem. v2 (Ben Skeggs): - rebased v3: fixed false-detections and threshold reprogrammation handling on nv50:nvc0 Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

| | * drm/nouveau/pbus: add a PBUS subdev that hands IRQs to the right subdevsMartin Peres2013-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are going to use PTHERM's IRQs for thermal monitoring but we need to route them first. On nv31-50, PBUS's IRQ line is shared with GPIOs IRQs. It seems like nv10-31 GPIO interruptions aren't well handled. I kept the original behaviour but it is wrong and may lead to an IRQ storm. Since we enable all PBUS IRQs, we need a way to avoid being stormed if we don't handle them. The solution I used was to mask the IRQs that have not been handled. This will also print one message in the logs to let us know. v2: drop the shared intr handler because of was racy v3: style fixes v4: drop a useless construct in the chipset-dependent INTR v5: add BUS to the disable mask v6 (Ben Skeggs): - general tidy to match the rest of the driver's style - nva3->nvc0, nva3 can be serviced just fine with nv50.c, rnndb even notes that the THERM_ALARM bit got left in the hw until fermi anyway.. so, it's not going to conflict - removed the peephole and user stuff, for the moment.. will handle them later if we find a good reason to actually care.. - limited INTR_EN to just what we can handle for now, mostly to prevent spam of unknown status bits (seen on at least nv4x) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

Compared to the original submission I've reinstated the setup flexibility you'd like to retain, kerneldoc has been reviewed by Laurent Pinchart and Rob Clark reviewed the code changes. Quick overview of the changes: - Cleaned-up library interface for drivers using the fb helper, also simplified the fb allocation callback since no driver supported reallocating the fb on-the-fly. And the fbdev/fbcon code keeps pointers to the old mapping around anyway, so reallocating backing storage will be much more work. - No longer call the crtc helper "disable everything" function at init time, but allow drivers to do so. Motivated by i915's fastboot effort and allows us to drop a bunch of noop dummy functions just to avoid calling NULL function pointers from i915.ko. - Properly clear old state when doing modeset calls, the fb helper left some old modes in there and unconditionally set an fb (even when disabling a crtc). The crtc helpers didn't care, but i915 modeset code can now drop a few special cases. - Full kerneldoc for the fb helper. Yay! - My version of the "don't sleep in panic ->unblank calls". The patch is already in -mm, I guess Andrew can drop it as soon as this pull lands in drm-next. * 'drm-fb-helper' of git://people.freedesktop.org/~danvet/drm: drm/fb-helper: remove unused members of struct drm_fb_helper drm/fb-helper: don't sleep for screen unblank when an oopps is in progress drm/fb-helper: improve kerneldoc drm/<drivers>: simplify ->fb_probe callback drm/fb-helper: streamline drm_fb_helper_single_fb_probe drm/fb-helper: directly call set_par from the hotplug handler drm/fb-helper: fixup set_config semantics drm/i915: rip out helper->disable noop functions drm/fb-helper: don't disable everything in initial_config drm/tegra: don't set up initial fbcon config twice drm/fb-helper: unexport drm_fb_helper_single_fb_probe drm/fb-helper: unexport drm_fb_helper_panic drm/fb-helper: kill drm_fb_helper_restore drm: review locking for drm_fb_helper_restore_fbdev_mode

| * | drm: revamp framebuffer cleanup interfacesDaniel Vetter2013-01-20

These framebuffers will be reaped when their assoiciated fb is closed. Now these two cases are set up differently, the framebuffers are on different lists and hence destruction needs to clean up different things. Also, for userspace framebuffers we remove them from any current usage, whereas for internal framebuffers it is assumed that the driver has done this already. Long story short, we need two different ways to cleanup such drivers. Three functions are involved in total: - drm_framebuffer_remove: Convenience function which removes the fb from all active usage and then drops the passed-in reference. - drm_framebuffer_unregister_private: Will remove driver-private framebuffers from relevant lists and drop the corresponding references. Should be called for driver-private framebuffers before dropping the last reference (or like for a lot of the drivers where the fbdev is embedded someplace else, before doing the cleanup manually). - drm_framebuffer_cleanup: Final cleanup for both classes of fbs, should be called by the driver's ->destroy callback once the last reference is gone. This patch just rolls out the new interfaces and updates all drivers (by adding calls to drm_framebuffer_unregister_private at all the right places)- no functional changes yet. Follow-on patches will move drm core code around and update the lifetime management for framebuffers, so that we are no longer required to keep framebuffers alive by locking mode_config.mutex. I've also updated the kerneldoc already. vmwgfx seems to again be a bit special, at least I haven't figured out how the fbdev support in that driver works. It smells like it's external though. v2: The i915 driver creates another private framebuffer in the load-detect code. Adjust its cleanup code, too.

After this patch there are only a few places in cleanup functions left which access ->pin_refcount without locking. But I'm hoping that those are safe and some other code invariant guarantees that this won't blow up. In any case, I only need to fix up pin/unpin to make ->pageflip work safely, so let's keep it at that. Add a comment to the header to explain the new locking rule.

| * | drm/nouveau: protect evo_wait/evo_kick sections with a channel mutexDaniel Vetter2013-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With per-crtc locks modeset operations can run in parallel, and the cursor code uses the device-global evo master channel for hw frobbing. But the pageflip code can also sync with the master under some circumstances. Hence just wrap things up in a mutex to ensure that pushbuf access doesn't intermingle. The approach here is a bit overkill since the per-crtc channels used to schedule the pageflips could probably be used without this pushbuf locking, but I'm not familiar enough with the nouveau codebase to be sure of that. v2: Add missing mutex_init to avoid angering lockdep.

| * | drm/<drivers>: reorder framebuffer init sequenceDaniel Vetter2013-01-20
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With more fine-grained locking we can no longer rely on the big mode_config lock to prevent concurrent access to mode resources like framebuffers. Instead a framebuffer becomes accessible to other threads as soon as it is added to the relevant lookup structures. Hence it needs to be fully set up by the time drivers call drm_framebuffer_init. This patch here is the drivers part of that reorg. Nothing really fancy going on safe for three special cases. - exynos needs to be careful to properly unref all handles. - nouveau gets a resource leak fixed for free: one of the error cases didn't cleanup the framebuffer, which is now moot since the framebuffer is only registered once it is fully set up. - vmwgfx requires a slight reordering of operations, I'm hoping I didn't break anything (but it's refcount management only, so should be safe). v2: Split out exynos, since it's a bit more hairy than expected. v3: Drop bogus cirrus hunk noticed by Richard Wilbur. v4: Split out vmwgfx since there's a small change in return values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes regression introduced in commit 70790f4f "drm/nouveau/clock: pull in the implementation from all over the place" When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set, the PLLs it is used for got limited to only the first two VPLLs. nv50_crtc_set_clock was only called to change VPLLs, so it didn't limit what it was used for in any way. Since nvc0_clock_pll_set is used for all PLLs, it has to specify which PLLs the code is used for, and only listed the first two VPLLs. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58735 This patch is a -stable candidate for 3.7.

| * drm/nv17-50: restore fence buffer on resumeMarcin Slusarz2013-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 5e120f6e4b3f35b741c5445dfc755f50128c3c44 "drm/nouveau/fence: convert to exec engine, and improve channel sync" nouveau fence sync implementation for nv17-50 and nvc0+ started to rely on state of fence buffer left by previous sync operation. But as pinned bo's (where fence state is stored) are not saved+restored across suspend/resume, we need to do it manually. nvc0+ was fixed by commit d6ba6d215a538a58f0f0026f0961b0b9125e8042 "drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

| * drm/nouveau: fix blank LVDS screen regression on pre-nv50 cardsMarcin Slusarz2013-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate from create/destroy") started to call display init routines on pre-nv50 hardware on module load. But LVDS init code sets driver state in a way which prevents modesetting code from operating properly. nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to NV_DPMS_CLEARED. drm_crtc_helper_set_mode nv04_dfp_prepare nv04_lvds_dpms(DRM_MODE_DPMS_OFF) nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too, so it skips calling some crucial lvds scripts.

| * drm/nouveau: do not forcibly power on lvds panelsBen Skeggs2013-01-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix was put in place to fix a bug where the eDP panel on certain laptops fails to respond over the aux channel after suspend. It appears that on some systems (Dell M6600, with LVDS panel) there's a very bad interaction with the eDP init table that causes the SOR to get very confused and not drive the panel correctly, leading to bleed. A DPMS off/on cycle is enough to bring it back, but, this will avoid the problem by not touching the panel GPIOs at times we're not meant to. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
