We forgot to add VLV_DISPLAY_BASE to the VLV sprite registers, which caused the sprites to not work at all. Signed-off-by:

The PIPECONF color range bit doesn't appear to be effective, on HDMI outputs at least. The color range bit in the port register works though, so let's use it. I have not yet verified whether the PIPECONF bit works on DP outputs. This reverts commit 83a2af88. Signed-off-by:

The current PLL settings produce a rather unstable picture when I hook up a VLV to my HP ZR24w display via a VGA cable. According to VLV2A0_DP_eDP_HDMI_DPIO_driver_vbios_notes_9, we should use the the same LPF coefficients for DAC as we do for HDMI and RBR DP. And indeed that seems to cure the shivers. v2: Add the name of the relevant document to the commit message Signed-off-by:

If the current GPU frquency is below RPe, and we're asked to increase it, just go directly to RPe. This should provide better performance faster than letting the frequency trickle up in response to the up threshold interrupts. For now just do it for VLV, since that matches quite closely how VLV used to operate when the rps delayed timer kept things at RPe always. Signed-off-by:

There's little point in increasing the GPU frequency from the delayed rps work on VLV. Now when the GPU is idle, the GPU frequency actually keeps dropping gradually until it hits the minimum, whereas previously it just ping-ponged constantly between RPe and RPe-1. Signed-off-by:

I can't find GEN6_RP_INTERRUPT_LIMITS (0xA014) anywhere in VLV docs. Reading it always returns zero from what I can tell, and eliminating it doesn't seem to make any difference to the behaviour of the system. Signed-off-by:

Eliminate the weird inverted logic from the rps new_delay comparison. Signed-off-by:

It seems that even though Punit reports the frequency change to have been completed, it still reports the old frequency in the status register for some time. So rather than polling for Punit to complete the frequency change after each request, poll before. This gets rid of the spurious "Punit overrode GPU freq" messages. This also lets us continue working while Punit is performing the actual frequency change. As a result, openarena demo088-test1 timedemo average fps is increased by ~5 fps, and the slowest frame duration is reduced by ~25%. The sysfs cur_freq file always reads the current frequency from Punit anyway, so having rps.cur_delay be slightly off at times doesn't matter. Signed-off-by:

Always print both the MHz value and raw register value for rps stuff. Also kill a somewhat pointless local 'rpe' variable and just use dev_priv->rps.rpe_delay. While at it clean up the caps in "GPU" and "Punit" debug messages. Signed-off-by:

Report back the user error of attempting to setup a CRTC with an invalid framebuffer pitch.

Git commit 90797e6d ("drm/i915: create compact dma scatter lists for gem objects") makes certain assumptions about the under laying DMA API that are not always correct. On a ThinkPad X230 with an Intel HD 4000 with Xen during the bootup I see: [drm:intel_pipe_set_base] *ERROR* pin & fence failed [drm:intel_crtc_set_config] *ERROR* failed to set mode on [CRTC:3], err = -28 Bit of debugging traced it down to dma_map_sg failing (in i915_gem_gtt_prepare_object) as some of the SG entries were huge (3MB). That unfortunately are sizes that the SWIOTLB is incapable of handling - the maximum it can handle is a an entry of 512KB of virtual contiguous memory for its bounce buffer. (See IO_TLB_SEGSIZE). Previous to the above mention git commit the SG entries were of 4KB, and the code introduced by above git commit squashed the CPU contiguous PFNs in one big virtual address provided to DMA API. This patch is a simple semi-revert - were we emulate the old behavior if we detect that SWIOTLB is online. If it is not online then we continue on with the new compact scatter gather mechanism. An alternative solution would be for the the '.get_pages' and the i915_gem_gtt_prepare_object to retry with smaller max gap of the amount of PFNs that can be combined together - but with this issue discovered during rc7 that might be too risky.

Because calling intel_dp_encoder_destroy inside intel_edp_init_connector is just wrong. This is the initialization path, so we should properly unwind all the initialization through the whole caller stack. On the intel_dp_encoder_destroy function we do the following: 1 - Call i2c_del_adapter 2 - Call drm_encoder_cleanup 3 - If edp: 3.1 - Cancel panel_vdd_work 3.2 - Call ironlake_panel_vdd_of_sync 4 - Free the encoder And here is how we unwind each specific step: 1 - We have intel_dp_init_connector -> intel_dp_i2c_init -> i2c_dp_aux_add_bus -> i2c_add_adapter, so we call i2c_del_dapter at intel_dp_init_connector 2 - Call it in the same function that called drm_encoder_init 3 - Call it in the same function that called INIT_DELAYED_WORK 4 - Free it in the same function that allocated it Signed-off-by: -

In case we detect a "ghost eDP", intel_edp_init_connector frees both the connector and encoder and then returns. On Haswell, intel_ddi_init then tries to use the freed encoder on the HDMI initialization path since the following commit: commit 21a8e6a4 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Apr 10 23:28:35 2013 +0200 drm/i915: don't setup hdmi for port D edp in ddi_init So now on intel_ddi_init we check for the "ghost eDP" case and return without trying to initialize HDMI. This way we won't try to read the freed "intel_encoder" struct in the next "if" statement. Signed-off-by:

Paulo Zanoni authored
By the time we call intel_dp_destroy (which destroys the connector) the encoder may have been destroyed already, so if we use it we may be reading some free memory. That happens in drm_mode_config_cleanup() and also inside intel_dp_init_connector() when we detect a ghost eDP. I also hope this may solve some random memory bugs. Reported by kmemcheck.

This reverts commit 160954b7. This was rearming the workqueue with a 0 timeout, causing a WARN_ON, and possible loop. Daniel writes: "I've looked a bit into this and I think we need to have a separate work struct for recovering these lost hotplug events since the continuous self-rearming case is a real risk (e.g. if a connector flip-flops all the time). At least I don't see a sane way to block out re-arming with the current code in a simple way. So reverting the offender seems like the right thing and I'll go back to the drawing board for 3.12."
