If the requested size is less than what the full range of pdps can address, we end up setting pdps for only the requested area. The logical context however needs all pdp entries to be valid. Prior to commit 06fda602 ("drm/i915: Create page table allocators") we have been writing pdp entries with dma address of zero instead of valid pdps. This is supposedly bad even if those pdps are not addressed. As commit 06fda602 ("drm/i915: Create page table allocators") introduced more dynamic structure for pdps, we ended up oopsing when we populated the lrc context. Analyzing this oops revealed the fact that we have not been writing valid pdps with bsw, as it is doing the ppgtt init with 2GB limit in some cases. We should do the right thing and setup the non addressable part pdps/pde/pte to scratch page through the minimal structure by having just pdp with pde entries pointing to same page with pte entries pointing to scratch page. But instead of going through that trouble, setup all the pdps through individual pd pages and pt entries, even for non addressable parts. And let the clear range point them to scratch page. This way we populate the lrc with valid pdps and wait for dynamic page allocation work to land, and do the heavy lifting for truncating page table tree according to usage. The regression of oopsing in init was introduced by commit 06fda602 ("drm/i915: Create page table allocators") v2: Clear the range for the unused part also (Ville) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89350 Cc: Michel Thierry <michel.thierry@intel.com> Cc: Ben Widawsky <benjamin.widawsky@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by:

In invalidate and flush functions of eDP DRRS, if deferred downclock work starts execution at a time window between acquiring the drrs mutex and cancellation of the deferred work (intel_edp_drrs_downclock_work), then deferred work will find drrs mutex locked and wait for the same. Meanwhile the function that acquired mutex drrs invalidate/flush will wait for the completion of the deferred work before releasing the mutex. Thats a deadlock. To avoid such deadlock scenario, this change cancels the deferred work before acquiring the mutex at invalidate and flush functions. Signed-off-by:

The current minimum vco frequency leaves us with a gap in our supported frequencies at 233-243 MHz. Your typical 2560x1440@60 display wants a pixel clock of 241.5 MHz, which is just withing that gap. Reduce the allowed vco min frequency to 4.8GHz to reduce the gap to 233-240 MHz, and thus allow such displays to work. 4.8 GHz is actually the documented (at least in some docs) limit of the PLL, and we just picked 4.86 GHz originally because that was the lowest value produced by the PLL spreadsheet, which obviously didn't consider 2560x1440 displays.

This reverts commit 3f678c96. We've been a bit too optimistic with this one here :( The trouble is that internally we're still using these plane update/disable hooks. Which was totally ok pre-atomic since the drm core did all the book-keeping updating and these just mostly updated hw state. But with atomic there's lots more going on, and it causes heaps of trouble with the load detect code. This one specifically cause a deadlock since both the load detect code and the nested plane atomic helper functions tried to grab the same locks. It only blows up because of the evil tricks though we play with the implicit ww acquire context. Applying this revert unearths the NULL deref on already freed framebuffer objects reported as a regression in 4.0 by various people. Fixing this will be fairly invasive, hence revert even for the 4.1-next queue.

With the two-step reset counter increments which braket the actual reset code and the subsequent wake-up we're guaranteeing that all the lockless waiters _will_ be woken up. And since we unconditionally bail out of waits with -EAGAIN (or -EIO) in that case there is not risk of lost interrupt enabling bits when the lockless wait code races against a gpu reset.

The cursor size fields in intel_crtc just duplicate the data from cursor->state.crtc_{w,h} so we don't need them any more. Worse, their use in the watermark code actually introduces a subtle bug since they don't get updated to mirror the state values until the plane commit stage, which is *after* we've already used them to calculate new watermark values. This happens because we had to move watermark updates slightly earlier (outside vblank evasion) in commit commit 32b7eeec Author: Matt Roper <matthew.d.roper@intel.com> Date: Wed Dec 24 07:59:06 2014 -0800 drm/i915: Refactor work that can sleep out of commit (v7) Dropping the intel_crtc fields and just using the state values (which are properly updated by the time watermark updates happen) should solve the problem. Aside from the actual removal of the struct fields (which are formatted in a way that I couldn't figure out how to match in Coccinelle), the rest of this patch was generated via the following semantic patch: // Drop assignment @@ struct intel_crtc *C; struct drm_plane_state S; @@ ( - C->cursor_width = S.crtc_w; | - C->cursor_height = S.crtc_h; ) // Replace usage @@ struct intel_crtc *C; expression E; @@ ( - C->cursor_width + C->base.cursor->state->crtc_w | - C->cursor_height + C->base.cursor->state->crtc_h | - to_intel_crtc(E)->cursor_width + E->cursor->state->crtc_w | - to_intel_crtc(E)->cursor_height + E->cursor->state->crtc_h ) v2: Rebase Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Joe Konno <joe.konno@linux.intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89346Signed-off-by:

Since the beginning, sysfs/connector/status has done a heavyweight detection of the current connector status. But no user, such as upowerd or logind, has ever desired to initiate a probe. Move the probing into a new attribute so that existing readers get the behaviour they desire. v2: David Herrmann suggested using "echo detect > /sys/.../status" to trigger the probing, which is a fine idea. This extends that to also allow the user to apply the force detection overrides at runtime. v3: Now with airlied's email address fixed! Requires sysfs_streq() Signed-off-by:

Originally it was impossible to be dropping the last refcount in this function since there was always one around still from the idr. But in commit 83f45fc3 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Aug 6 09:10:18 2014 +0200 drm: Don't grab an fb reference for the idr we've switched to weak references, broke that assumption but forgot to fix it up. Since we still force-disable planes it's only possible to hit this when racing multiple rmfb with fbdev restoring or similar evil things. As long as userspace is nice it's impossible to hit the BUG_ON. But the BUG_ON would most likely be hit from fbdev code, which usually invovles the console_lock besides all modeset locks. So very likely we'd never get the bug reports if this was hit in the wild, hence better be safe than sorry and backport. Spotted by Matt Roper while reviewing other patches.
