2020-01-27Revert "drm/sun4i: drv: Allow framebuffer modifiers in mode config"Jernej Skrabec1-1/+0
This reverts commit 9db9c0cf5895e4ddde2814360cae7bea9282edd2. Setting mode_config.allow_fb_modifiers manually is completely unnecessary. It is set automatically by drm_universal_plane_init() based on the fact if modifier list is provided or not. Even more, it breaks DE2 and DE3 as they don't support any modifiers beside linear. Modifiers aware applications can be confused by provided empty modifier list - at least linear modifier should be included, but it's not for DE2 and DE3.

2020-01-21drm/panfrost: Add the panfrost_gem_mapping conceptBoris Brezillon9-74/+300
With the introduction of per-FD address space, the same BO can be mapped in different address space if the BO is globally visible (GEM_FLINK) and opened in different context or if the dmabuf is self-imported. The current implementation does not take case into account, and attaches the mapping directly to the panfrost_gem_object. Let's create a panfrost_gem_mapping struct and allow multiple mappings per BO. The mappings are refcounted which helps solve another problem where mappings were torn down (GEM handle closed by userspace) while GPU jobs accessing those BOs were still in-flight. Jobs now keep a reference on the mappings they use. v2 (robh): - Minor review comment clean-ups from Steven - Use list_is_singular helper - Just WARN if we add a mapping when madvise state is not WILLNEED. With that, drop the use of object_name_lock. v3 (robh): - Revert returning list iterator in panfrost_gem_mapping_get() Fixes: a5efb4c9a562 ("drm/panfrost: Restructure the GEM object creation") Fixes: 7282f7645d06 ("drm/panfrost: Implement per FD address spaces") Cc: <stable@vger.kernel.org> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Rob Herring <robh@kernel.org> Acked-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200116021554.15090-1-robh@kernel.org
2020-01-17drm/dp_mst: Handle SST-only branch device caseWayne Lin1-60/+80
[Why] While handling LINK_ADDRESS reply, current code expects a peer device can handle sideband message once the peer device type is reported as DP_PEER_DEVICE_MST_BRANCHING. However, when the connected device is a SST branch case, it can't handle the sideband message(MST_CAP=0 in DPCD 00021h). Current code will try to send LINK_ADDRESS to SST branch device and end up with message timeout and monitor can't display normally. As the result of that, we should take SST branch device into account. [How] According to DP 1.4 spec, we can use Peer_Device_Type as DP_PEER_DEVICE_MST_BRANCHING and Message_Capability_Status as 0 to indicate peer device as a SST-only branch device. Fix following: - Add the function drm_dp_mst_is_dp_mst_end_device() to decide whether a peer device connected to a DFP is mst end device. Which also indicates if the peer device is capable of handling message or not. - Take SST-only branch device case into account in drm_dp_port_set_pdt() and add a new parameter 'new_mcs'. Take sst branch device case as the same case as DP_PEER_DEVICE_DP_LEGACY_CONV and DP_PEER_DEVICE_SST_SINK. All original handling logics remain. - Take SST-only branch device case into account in drm_dp_mst_port_add_connector(). - Fix some parts in drm_dp_mst_handle_link_address_port() to have SST branch device case into consideration. - Fix the arguments of drm_dp_port_set_pdt() in drm_dp_mst_handle_conn_stat(). - Have SST branch device also report connector_status_connected when the ddps is true in drm_dp_mst_detect_port() - Fix the arguments of drm_dp_port_set_pdt() in drm_dp_delayed_destroy_port() Changes since v1:(https://patchwork.kernel.org/patch/11323079/) * Squash previous patch into one patch and merge the commit message here. * Combine the if statements mentioned in comments Fixes: c485e2c97dae ("drm/dp_mst: Refactor pdt setup/teardown, add more locking") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <hwentlan@amd.com> Cc: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200117060350.26358-2-Wayne.Lin@amd.com
2020-01-15drm/dp_mst: Have DP_Tx send one msg at a timeWayne Lin1-2/+12
[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 Lin1-1/+24
[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.

For high-res (8K) or HFR (4K120) displays, using uncompressed pixel formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the "interesting" modes would be disabled, leaving only low-res or low framerate modes. This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS clock is exceeded. Verified that 8K30 and 4K120 are now available and working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.

2020-01-07drm/fb-helper: Round up bits_per_pixel if possibleGeert Uytterhoeven1-1/+6
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 Tsai2-3/+13
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: Limit audio CDCLK>=2*BCLK constraint back to GLK onlyKai Vehmanen1-2/+2
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 Lin1-1/+1
[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.

2020-01-01drm/amdgpu: correct RLC firmwares loading sequenceEvan Quan2-2/+2
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 Wilson1-1/+2
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.

2019-12-16drm/i915: Copy across scheduler behaviour flags across submit fencesChris Wilson2-26/+89
We want the bonded request to have the same scheduler properties as its master so that it is placed at the same depth in the queue. For example, consider we have requests A, B and B', where B & B' are a bonded pair to run in parallel on two engines. A -> B \- B' B will run after A and so may be scheduled on an idle engine and wait on A using a semaphore. B' sees B being executed and so enters the queue on the same engine as A. As B' did not inherit the semaphore-chain from B, it may have higher precedence than A and so preempts execution. However, B' then sits on a semaphore waiting for B, who is waiting for A, who is blocked by B. Ergo B' needs to inherit the scheduler properties from B (i.e. the semaphore chain) so that it is scheduled with the same priority as B and will not be executed ahead of Bs dependencies. Furthermore, to prevent the priorities changing via the expose fence on B', we need to couple in the dependencies for PI. This requires us to relax our sanity-checks that dependencies are strictly in order. v2: Synchronise (B, B') execution on all platforms, regardless of using a scheduler, any no-op syncs should be elided.
