2016-07-07drm/i915: Check for invalid cloning earlier during modesetVille Syrjälä
Move the encoder cloning check to happen earlier in the modeset. The main benefit will be that the debug output from a failed modeset will be less confusing as output_types can not indicate an invalid configuration during the later computation stages. For instance, what happened to me was kms_setmode was attempting one of its invalid cloning checks during which it asked for DP+VGA cloning on HSW. In this case the DP .compute_config() was executed after the FDI .compute_config() leaving the DP link clock (1.62 in this case) in port_clock, and then later the FDI BW computation tried to use that as the FDI link clock (which should always be 2.7). 1.62 x 2 wasn't enough for the mode it was trying to use, and so it ended up rejecting the modeset, not because of an invalid cloning configuration, but because of supposedly running out of FDI bandwidth. Took me a while to figure out what had actually happened.

2016-07-06drm/i915: avoid wait_for_atomic() in non-atomic host2guc_action()Dave Gordon
Rather than using wait_for_atomic() when chacking for a response from the GuC, we can get the effect of a hybrid spin/sleep wait by breaking it into two stages. First, spin-wait for up to 10us to minimise latency for "quick" commands; then, if that times out, sleep-wait for up 10ms (the maximum allowed for a "slow" command). Being able to do this depends on the recent patch 18f4b84 drm/i915: Use atomic waits for short non-atomic ones and is similar to the hybrid approach in 1758b90 drm/i915: Use a hybrid scheme for fast register waits (although we can't use that as-is, because that interface doesn't quite match what we need here).

After assigning ourselves as the new bottom-half, we must perform a cursory check to prevent a missed interrupt. Either we miss the interrupt whilst programming the hardware, or if there was a previous waiter (for a later seqno) they may be woken instead of us (due to the inherent race in the unlocked read of b->tasklet in the irq handler) and so we miss the wake up.

2016-07-05drm/i915: Replace lockless_dereference(bool) with READ_ONCE()Chris Wilson
After Joonas complained about using READ_ONCE() on the only use of the variable in the function, where the intent was to simply document that the read was intentionally racy and unlocked, I switched the READ_ONCE() over to lockless_dereference(). However, in linux-next that has a stronger type-check to only allow pointers and is no longer interchangeable with READ_ONCE(), see commit 331b6d8c7afc ("locking/barriers: Validate lockless_dereference() is used on a pointer type") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Fixes: 67d97da34917 ("drm/i915: Only start retire worker when idle") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1467705276-707-1-git-send-email-chris@chris-wilson.co.uk Reviewed-by: Mika Kuoppala <mika.kuoppala@intel.com>
2016-07-05drm/bridge: analogix_dp: some rockchip chips need to flip REF_CLK bit settingYakir Yang
As vendor document indicate, when REF_CLK bit set 0, then DP phy's REF_CLK should switch to 24M source clock. But due to IC PHY layout mistaken, some chips need to flip this bit(like RK3288), and unfortunately they didn't indicate in the DP version register. That's why we have to make this little hack.
