2010-05-28drm/i915: Rebind bo if currently bound with incorrect alignment.Chris Wilson
Whilst pinning the buffer, check that that its current alignment matches the requested alignment. If it does not, rebind. This should clear up any final render errors whilst resuming, for reference: Bug 27070 - [i915] Page table errors with empty ringbuffer https://bugs.freedesktop.org/show_bug.cgi?id=27070 Bug 15502 - render error detected, EIR: 0x00000010 https://bugzilla.kernel.org/show_bug.cgi?id=15502 Bug 13844 - i915 error: "render error detected" https://bugzilla.kernel.org/show_bug.cgi?id=13844 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>

This bug was introduced by the following commit Author: Vasanthakumar Thiagarajan <vasanth@atheros.com> Date: Thu Apr 15 17:38:46 2010 -0400 ath9k: Remove ATH9K_TX_SW_ABORTED and introduce a bool for this purpose Wrong buffer is checked for bf_tx_aborted field in ath_tx_num_badfrms(), this may result in a rate scaling with wrong feedback (number of unacked frames in this case). It is the last one in the chain of buffers for an aggregate frame that should be checked. Also it misses the initialization of this field in the buffer, this may lead to a situation where we stop the sw retransmission of failed subframes associated to this buffer.

The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
