2023-01-05drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interruptxurui8-15/+36
HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.

2023-01-05drm/bridge_connector: rely on drm_kms_helper_poll_* for HPD enablementDmitry Baryshkov1-5/+13
Use drm_connector's helpers enable_hpd and disable_hpd to enable and disable HPD automatically by the means of drm_kms_helper_poll_* functions. As the drm_bridge_connector_enable_hpd() and drm_bridge_connector_disable_hpd() functions are now unused, replace them with stubs to ease driver migration. Enabling the HPD from drm_bridge_connector_init() can happen too early, before the driver is prepared to handle HPD events. As the drm_bridge_connector_enable_hpd() is empty anyway, drop this call anyway.

Introduce two drm_connector_helper_funcs: enable_hpd() and disable_hpd(). They are called by drm_kms_helper_poll_enable() and drm_kms_helper_poll_disable() (and thus drm_kms_helper_poll_init() and drm_kms_helper_poll_fini()) respectively. This allows DRM drivers to rely on drm_kms_helper_poll for enabling and disabling HPD detection rather than doing that manually.

2023-01-05drm/bridge: panel: Prevent ERR_PTR DereferenceMaxime Ripard1-4/+5
Commit 5ea6b1702781 ("drm/panel: Add prepare_prev_first flag to drm_panel") introduced an access to the bridge pointer in the devm_drm_panel_bridge_add_typed() function. However, due to the unusual ERR_PTR check when getting that pointer, the pointer access is done even though the pointer might be an error pointer. Rework the function for a more traditional design that will return immediately if it gets an ERR_PTR so that we never access the pointer in that case.

If intel_gvt_dma_map_guest_page failed, it will call ppgtt_invalidate_spt, which will finally free the spt. But the caller function ppgtt_populate_spt_by_guest_entry does not notice that, it will free spt again in its error path. Fix this by canceling the mapping of DMA address and freeing sub_spt. Besides, leave the handle of spt destroy to caller function instead of callee function when error occurs.

2023-01-04drm/i915/dp: change aux_ctl reg read to polling readArun R Murthy1-9/+5
The busy timeout logic checks for the AUX BUSY, then waits for the timeout period and then after timeout reads the register for BUSY or Success. Instead replace interrupt with polling so as to read the AUX CTL register often before the timeout period. Looks like there might be some issue with interrupt-on-read. Hence changing the logic to polling read. v2: replace interrupt with polling read v3: use usleep_rang instead of msleep, updated commit msg v4: use intel_wait_for_regiter internal function v5: use __intel_de_wait_for_register with 500us slow and 10ms fast timeout v6: check return value of __intel_de_wait_for_register v7: using default 2us for intel_de_wait_for_register Signed-off-by: Arun R Murthy <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2023-01-03drm/msm/dp: do not complete dp_aux_cmd_fifo_tx() if irq is not for aux transferKuogee Hsieh1-0/+4
There are 3 possible interrupt sources are handled by DP controller, HPDstatus, Controller state changes and Aux read/write transaction. At every irq, DP controller have to check isr status of every interrupt sources and service the interrupt if its isr status bits shows interrupts are pending. There is potential race condition may happen at current aux isr handler implementation since it is always complete dp_aux_cmd_fifo_tx() even irq is not for aux read or write transaction. This may cause aux read transaction return premature if host aux data read is in the middle of waiting for sink to complete transferring data to host while irq happen. This will cause host's receiving buffer contains unexpected data. This patch fixes this problem by checking aux isr and return immediately at aux isr handler if there are no any isr status bits set. Current there is a bug report regrading eDP edid corruption happen during system booting up. After lengthy debugging to found that VIDEO_READY interrupt was continuously firing during system booting up which cause dp_aux_isr() to complete dp_aux_cmd_fifo_tx() prematurely to retrieve data from aux hardware buffer which is not yet contains complete data transfer from sink. This cause edid corruption. Follows are the signature at kernel logs when problem happen, EDID has corrupt header panel-simple-dp-aux aux-aea0000.edp: Couldn't identify panel via EDID Changes in v2: -- do complete if (ret == IRQ_HANDLED) ay dp-aux_isr() -- add more commit text Changes in v3: -- add Stephen suggested -- dp_aux_isr() return IRQ_XXX back to caller -- dp_ctrl_isr() return IRQ_XXX back to caller Changes in v4: -- split into two patches Changes in v5: -- delete empty line between tags Changes in v6: -- remove extra "that" and fixed line more than 75 char at commit text Fixes: c943b4948b58 ("drm/msm/dp: add displayPort driver support") Signed-off-by: Kuogee Hsieh <[email protected]> Tested-by: Douglas Anderson <[email protected]> Reviewed-by: Abhinav Kumar <[email protected]> Reviewed-by: Dmitry Baryshkov <[email protected]> Patchwork: https://patchwork.freedesktop.org/patch/516121/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Abhinav Kumar <[email protected]>

[Why] We skip dsc_validation on pipes that are underlays, but in the acquire_dsc code we don't have this check. In certain conditions (when underlay pipe index is lower) we will assign the dsc resource to the underlay pipe and skip the base pipe. Now during dsc_validation we will skip the underlay pipe (this has the dsc resource) but try to validate the base pipe(this doesn't have a dsc resource) due to this mismatch we hit a NULLPTR [How] In the acquire_dsc add a check for underlay pipe so we don't acquire a dsc resource for this pipe. This will match the acquire/validation conditions.

2023-01-03drm/amd/display: set ignore msa parameter only if freesync is enabledAurabindo Pillai1-2/+9
[Why&How] ignore_msa_timing_param is used by SubVP logic to determine if SubVP + DRR is possible. Linux does not support freesync on multi display config, which results in incorrect assumption of VRR support if we set this parameter when VRR is supported, but not enabled.

[why] During DP2.1 LL CTS if test equipment requests to change between DP2.1 and DP1.4 link rates, we need to swap between HPO and DIO encoders by remapping encoder resource.

2023-01-03drm/amd/display: update pixel rate div in enable streamWenjing Liu1-0/+12
[why] Pixel rate div depends on the type of encoder that we are enabling stream with. If we swap between HPO and DIO encoder at the time we call enable stream for the new encoder, we must reprogram pixel rate div based on the new encoder type.

[Why] On some monitors we see a brief flash of corruption during the monitor disable sequence caused by FIFO being disabled in the middle of an active DP stream. [How] Wait until DP vid stream is disabled before turning off the FIFO. The FIFO reset on DP unblank should take care of clearing any FIFO error, if any.

[Description] - Proper phantom pipe disable sequence was missing in commit_planes_for_stream - If disabling phantom pipe, turn on phantom OTG first, and turn off the phantom OTG after the plane is disabled - Also update sequence for enabling / disabling phantom streams (apply_ctx_to_hw). When enabling phantom pipes, enable before doing front end programming for phantom pipes. If disabling phantom pipes, disable after front end programming (i.e. after phantom plane disable) - TODO: Still need to properly handle transition case when a phantom pipe is transitioned directly into a real pipe (need to fully disable the phantom pipe first) Acked-by: Aurabindo Pillai <[email protected]> Signed-off-by: Alvin Lee <[email protected]> Reviewed-by: Jun Lei <[email protected]> Tested-by: Daniel Wheeler <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
