2021-08-10drm/msm/dp: do not end dp link training until video is readyKuogee Hsieh
Initialize both pre-emphasis and voltage swing level to 0 before start link training and do not end link training until video is ready to reduce the period between end of link training and video start to meet Link Layer CTS requirement. Some dongle main link symbol may become unlocked again if host did not end link training soon enough after completion of link training 2. Host have to re train main link if loss of symbol locked detected before end link training so that the coming video stream can be transmitted to sink properly. This fixes Link Layer CTS cases 4.3.2.1, 4.3.2.2, 4.3.2.3 and 4.3.2.4. Changes in v3: -- merge retrain link if loss of symbol locked happen into this patch -- replace dp_ctrl_loss_symbol_lock() with dp_ctrl_channel_eq_ok() Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org> Reviewed-by: Stephen Boyd <swboyd@chromium.org> Link: https://lore.kernel.org/r/1628196295-7382-7-git-send-email-khsieh@codeaurora.org Signed-off-by: Rob Clark <robdclark@chromium.org>

Remove special handling of replug interrupt and instead treat replug event as a sequential unplug followed by a plugin event.

2021-08-10drm/msm/dp: reset aux controller after dp_aux_cmd_fifo_tx() failed.Kuogee Hsieh
Aux hardware calibration sequence requires resetting the aux controller in order for the new setting to take effect. However resetting the AUX controller will also clear HPD interrupt status which may accidentally cause pending unplug interrupt to get lost. Therefore reset aux controller only when link is in connection state when dp_aux_cmd_fifo_tx() fail. This fixes Link Layer CTS cases 4.2.1.1 and 4.2.1.2.

2021-08-10drm/msm/dp: use dp_ctrl_off_link_stream during PHY compliance test runKuogee Hsieh
DP cable should always connect to DPU during the entire PHY compliance testing run. Since DP PHY compliance test is executed at irq_hpd event context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off(). dp_ctrl_off() is used for unplug event which is triggered when DP cable is dis connected.

2021-08-10drm/msm/dsi: Fix some reference counted resource leaksChristophe JAILLET
'of_find_device_by_node()' takes a reference that must be released when not needed anymore. This is expected to be done in 'dsi_destroy()'. However, there are 2 issues in 'dsi_get_phy()'. First, if 'of_find_device_by_node()' succeeds but 'platform_get_drvdata()' returns NULL, 'msm_dsi->phy_dev' will still be NULL, and the reference won't be released in 'dsi_destroy()'. Secondly, as 'of_find_device_by_node()' already takes a reference, there is no need for an additional 'get_device()'. Move the assignment to 'msm_dsi->phy_dev' a few lines above and remove the unneeded 'get_device()' to solve both issues.

The firewall is functionality-wise a copy of the firewall already implemented in gpu/host1x. It is copied here as it makes more sense for it to live on the DRM side, as it is only needed for userspace job submissions, and generally the data it needs to do its job is easier to access here.

2021-08-10drm/tegra: Allocate per-engine channel in core codeMikko Perttunen
To avoid code duplication, allocate the per-engine shared channel in the core code instead. This is the usual channel that all jobs are submitted to when MLOCKing is not in use. Once MLOCKs are implemented on Host1x side, we can also update this to avoid allocating a shared channel when MLOCKs are enabled.

2021-08-10drm/tegra: Boot VIC during runtime PM resumeMikko Perttunen
With the new UAPI implementation, engines are powered on and off when there are active jobs, and the core code handles channel allocation. To accommodate that, boot the engine as part of runtime PM instead of using the open_channel callback, which is not used by the new submit path.

2021-08-10gpu: host1x: Add option to skip firewall for a jobMikko Perttunen
The new UAPI will have its own firewall, and we don't want to run the firewall in the Host1x driver for those jobs. As such, add a parameter to host1x_job_alloc to specify if we want to skip the firewall in the Host1x driver.

2021-08-10gpu: host1x: Add support for syncpoint waits in CDMA pushbufferMikko Perttunen
Add support for inserting syncpoint waits in the CDMA pushbuffer. These waits need to be done in HOST1X class, while gather submitted by the application execute in engine class. Support is added by converting the gather list of job into a command list that can include both gathers and waits. When the job is submitted, these commands are pushed as the appropriate opcodes on the CDMA pushbuffer. Also supported are waits relative to the start of the job, which are useful for jobs doing multiple things with an engine that doesn't natively support pipelining. While at it, use 32-bit waits on chips that support them. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2021-08-10gpu: host1x: Add job release callbackMikko Perttunen

2021-08-10gpu: host1x: Add no-recovery modeMikko Perttunen
Add a new property for jobs to enable or disable recovery i.e. CPU increments of syncpoints to max value on job timeout. This allows for a more solid model for hanged jobs, where userspace doesn't need to guess if a syncpoint increment happened because the job completed, or because job timeout was triggered. On job timeout, we stop the channel, NOP all future jobs on the channel using the same syncpoint, mark the syncpoint as locked and resume the channel from the next job, if any. The future jobs are NOPed, since because we don't do the CPU increments, the value of the syncpoint is no longer synchronized, and any waiters would become confused if a future job incremented the syncpoint. The syncpoint is marked locked to ensure that any future jobs cannot increment the syncpoint either, until the application has recognized the situation and reallocated the syncpoint.

2021-08-10gpu: host1x: Add DMA fence implementationMikko Perttunen
Add an implementation of dma_fences based on syncpoints. Syncpoint interrupts are used to signal fences. Additionally, after software signaling has been enabled, a 30 second timeout is started. If the syncpoint threshold is not reached within this period, the fence is signalled with an -ETIMEDOUT error code. This is to allow fences that would never reach their syncpoint threshold to be cleaned up. The timeout can potentially be removed in the future after job tracking code has been refactored.
