2017-01-13Revert "drm/amdgpu: Only update the CUR_SIZE register when necessary"Michel Dänzer4-60/+30
This reverts commits 7c83d7abc9997cf1efac2c0ce384b5e8453ee870 and a1f49cc179ce6b7b7758ae3ff5cdb138d0ee0f56. They caused the HW cursor to disappear under various circumstances in the wild. I wasn't able to reproduce any of them, and I'm not sure what's going on. But those changes aren't a big deal anyway, so let's just revert for now.

2017-01-09drm/bridge: analogix dp: Fix runtime PM state on driver bindMarek Szyprowski1-0/+7
Analogix_dp_bind() can be called from component framework, which doesn't guarantee proper runtime PM state of the device during bind operation, so ensure that device is runtime active before doing any register access. This ensures that the power domain, to which DP module belongs, is turned on. While at it, also fix the unbalanced call to phy_power_on() in analogix_dp_bind() function. This patch solves the following kernel oops on Samsung Exynos5250 Snow board: Unhandled fault: imprecise external abort (0x406) at 0x00000000 pgd = c0004000 [00000000] *pgd=00000000 Internal error: : 406 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 PID: 75 Comm: kworker/0:2 Not tainted 4.9.0 #1046 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) Workqueue: events deferred_probe_work_func task: ee272300 task.stack: ee312000 PC is at analogix_dp_enable_sw_function+0x18/0x2c LR is at analogix_dp_init_dp+0x2c/0x50 ...

So they can figure out what is the optimal number of pages that can be contingously stitched together without fear of bounce buffer. We also expose an mechanism for sub-users of SWIOTLB API, such as Xen-SWIOTLB to set the max segment value. And lastly if swiotlb=force is set (which mandates we bounce buffer everything) we set max_segment so at least we can bounce buffer one 4K page instead of a giant 512KB one for which we may not have space.

This issue has not been observed on revision 1, while the recovery mechanism introduces a different issue, where the END_OF_FRAME interrupt doesn't fire while drm is waiting for vblanks. On rev1: recover from sync lost errors by simply clearing the RASTER_ENABLE bit in the RASTER_CTRL register and re-enabling it again as is suggested by the datasheet.

2017-01-03drm/i915: Move the min_pixclk[] handling to the end of readoutVille Syrjälä1-16/+16
Trying to determine the pixel rate of the pipe can't be done until we know the clock, which means it can't be done until the encoder .get_config() hooks have been called. So let's move the min_pixclk[] stuff to the end of intel_modeset_readout_hw_state() when we actually have gathered all the required infromation.

2017-01-03drm/i915: Force VDD off on the new power seqeuencer before starting to use itVille Syrjälä1-7/+34
Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on. This fixes the following kind of warnings: WARNING: CPU: 0 PID: 123 at ../drivers/gpu/drm/i915/intel_runtime_pm.c:1455 intel_display_power_put+0x13a/0x170 [i915]() WARN_ON(!power_domains->domain_use_count[domain]) ... v2: Fix typos in comment (David) Cc: stable@vger.kernel.org Cc: Matwey V.
