2020-01-21drm/i915: Align engine->uabi_class/instance with i915_drm.hTvrtko Ursulin
In our ABI we have defined I915_ENGINE_CLASS_INVALID_NONE and I915_ENGINE_CLASS_INVALID_VIRTUAL as negative values which creates implicit coupling with type widths used in, also ABI, struct i915_engine_class_instance. One place where we export engine->uabi_class I915_ENGINE_CLASS_INVALID_VIRTUAL is from our our tracepoints. Because the type of the former is u8 in contrast to u16 defined in the ABI, 254 will be returned instead of 65534 which userspace would legitimately expect. Another place is I915_CONTEXT_PARAM_ENGINES. Therefore we need to align the type used to store engine ABI class and instance. v2: * Update the commit message mentioning get_engines and cc stable.

2020-01-15drm/dp_mst: Have DP_Tx send one msg at a timeWayne Lin
[Why] Noticed this while testing MST with the 4 ports MST hub from StarTech.com. Sometimes can't light up monitors normally and get the error message as 'sideband msg build failed'. Look into aux transactions, found out that source sometimes will send out another down request before receiving the down reply of the previous down request. On the other hand, in drm_dp_get_one_sb_msg(), current code doesn't handle the interleaved replies case. Hence, source can't build up message completely and can't light up monitors. [How] For good compatibility, enforce source to send out one down request at a time. Add a flag, is_waiting_for_dwn_reply, to determine if the source can send out a down request immediately or not. - Check the flag before calling process_single_down_tx_qlock to send out a msg - Set the flag when successfully send out a down request - Clear the flag when successfully build up a down reply - Clear the flag when find erros during sending out a down request - Clear the flag when find errors during building up a down reply - Clear the flag when timeout occurs during waiting for a down reply - Use drm_dp_mst_kick_tx() to try to send another down request in queue at the end of drm_dp_mst_wait_tx_reply() (attempt to send out messages in queue when errors occur) Cc: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200113093649.11755-1-Wayne.Lin@amd.com
2020-01-14drm/dp_mst: clear time slots for ports invalidWayne Lin
[Why] When change the connection status in a MST topology, mst device which detect the event will send out CONNECTION_STATUS_NOTIFY messgae. e.g. src-mst-mst-sst => src-mst (unplug) mst-sst Currently, under the above case of unplugging device, ports which have been allocated payloads and are no longer in the topology still occupy time slots and recorded in proposed_vcpi[] of topology manager. If we don't clean up the proposed_vcpi[], when code flow goes to try to update payload table by calling drm_dp_update_payload_part1(), we will fail at checking port validation due to there are ports with proposed time slots but no longer in the mst topology. As the result of that, we will also stop updating the DPCD payload table of down stream port. [How] While handling the CONNECTION_STATUS_NOTIFY message, add a detection to see if the event indicates that a device is unplugged to an output port. If the detection is true, then iterrate over all proposed_vcpi[] to see whether a port of the proposed_vcpi[] is still in the topology or not. If the port is invalid, set its num_slots to 0. Thereafter, when try to update payload table by calling drm_dp_update_payload_part1(), we can successfully update the DPCD payload table of down stream port and clear the proposed_vcpi[] to NULL.

Intel ID: PSIRT-TA-201910-001 CVEID: CVE-2019-14615 Intel GPU Hardware prior to Gen11 does not clear EU state during a context switch. This can result in information leakage between contexts. For Gen8 and Gen9, hardware provides a mechanism for fast cleardown of the EU state, by issuing a PIPE_CONTROL with bit 27 set. We can use this in a context batch buffer to explicitly cleardown the state on every context switch. As this workaround is already in place for gen8, we can borrow the code verbatim for Gen9.

2020-01-07drm/fb-helper: Round up bits_per_pixel if possibleGeert Uytterhoeven
When userspace requests a video mode parameter value that is not supported, frame buffer device drivers should round it up to a supported value, if possible, instead of just rejecting it. This allows applications to quickly scan for supported video modes. Currently this rule is not followed for the number of bits per pixel, causing e.g. "fbset -depth N" to fail, if N is smaller than the current number of bits per pixel. Fix this by returning an error only if bits per pixel is too large, and setting it to the current value otherwise. See also Documentation/fb/framebuffer.rst, Section 2 (Programmer's View of /dev/fb*").

2020-01-07drm/sun4i: tcon: Set RGB DCLK min. divider based on hardware modelChen-Yu Tsai
In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.") it was assumed that all TCON variants support a minimum divider of 1 if only DCLK was used. However, the oldest generation of hardware only supports minimum divider of 4 if only DCLK is used. If a divider of 1 was used on this old hardware, some scrolling artifact would appear. A divider of 2 seemed OK, but a divider of 3 had artifacts as well. Set the minimum divider when outputing to parallel RGB based on the hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20) hardware, and a minimum of 1 for the rest. A value is not set for the TCON variants lacking channel 0. This fixes the scrolling artifacts seen on my A13 tablet. Fixes: 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.")

2020-01-07drm/i915/gt: Restore coarse power gatingChris Wilson
The coarse power gating was disabled as part of commit 2248a28384fe ("drm/i915/gen8+: Add RC6 CTX corruption WA") as a prelude to recover from the context corruption; the power gating itself has no direct impact on the RC6 context corruption. However, that recovery scheme was never implemented due to difficult corner cases, and so we no longer need to keep the power gating disabled.

2020-01-07drm/i915: Limit audio CDCLK>=2*BCLK constraint back to GLK onlyKai Vehmanen
Revert changes done in commit f6ec9483091f ("drm/i915: extend audio CDCLK>=2*BCLK constraint to more platforms"). Audio drivers communicate with i915 over HDA bus multiple times during system boot-up and each of these transactions result in matching get_power/put_power calls to i915, and depending on the platform, a modeset change causing visible flicker. GLK is the only platform with minimum CDCLK significantly lower than BCLK, and thus for GLK setting a higher CDCLK is mandatory. For other platforms, minimum CDCLK is close but below 2*BCLK (e.g. on ICL, CDCLK=176.4kHz with BCLK=96kHz). Spec-wise the constraint should be set, but in practise no communication errors have been reported and the downside if set is the flicker observed at boot-time. Revert to old behaviour until better mechanism to manage probe-time clocks is available. The full CDCLK>=2*BCLK constraint is still enforced at pipe enable time in intel_crtc_compute_min_cdclk().

2020-01-03drm/dp_mst: correct the shifting in DP_REMOTE_I2C_READWayne Lin
[Why] According to DP spec, it should shift left 4 digits for NO_STOP_BIT in REMOTE_I2C_READ message. Not 5 digits. In current code, NO_STOP_BIT is always set to zero which means I2C master is always generating a I2C stop at the end of each I2C write transaction while handling REMOTE_I2C_READ sideband message. This issue might have the generated I2C signal not meeting the requirement. Take random read in I2C for instance, I2C master should generate a repeat start to start to read data after writing the read address. This issue will cause the I2C master to generate a stop-start rather than a re-start which is not expected in I2C random read. [How] Correct the shifting value of NO_STOP_BIT for DP_REMOTE_I2C_READ case in drm_dp_encode_sideband_req().

2020-01-01drm/amdgpu: correct RLC firmwares loading sequenceEvan Quan
Per confirmation with RLC firmware team, the RLC should be unhalted after all RLC related firmwares uploaded. However, in fact the RLC is unhalted immediately after RLCG firmware uploaded. And that may causes unexpected PSP hang on loading the succeeding RLC save restore list related firmwares. So, we correct the firmware loading sequence to load RLC save restore list related firmwares before RLCG ucode. That will help to get around this issue.

2019-12-23drm/i915/gt: Ratelimit display power w/aChris Wilson
For very light workloads that frequently park, acquiring the display power well (required to prevent the dmc from trashing the system) takes longer than the execution. A good example is the igt_coherency selftest, which is slowed down by an order of magnitude in the worst case with powerwell cycling. To prevent frequent cycling, while keeping our fast soft-rc6, use a timer to delay release of the display powerwell.

First is not assuming rc6 value zero means GT is asleep since that can also mean GPU is fully busy and we do not want to enter the estimation path in that case. Second is ensuring monotonicity on the estimation path itself. I suspect what is happening is with extremely rapid park/unpark cycles we get no updates on the real rc6 and therefore have to careful not to unconditionally trust use last known real rc6 when creating a new estimation. v2: * Simplify logic by not tracking the estimate but last reported value.
