2024-03-06Revert "drm/udl: Add ARGB8888 as a format"Douglas Anderson1-1/+0
This reverts commit 95bf25bb9ed5dedb7fb39f76489f7d6843ab0475. Apparently there was a previous discussion about emulation of formats and it was decided XRGB8888 was the only format to support for legacy userspace [1]. Remove ARGB8888. Userspace needs to be fixed to accept XRGB8888.

2024-03-06drm/i915/dp: Fix connector DSC HW state readoutImre Deak5-7/+29
The DSC HW state of DP connectors is read out during driver loading and system resume in intel_modeset_update_connector_atomic_state(). This function is called for all connectors though and so the state of DSI connectors will also get updated incorrectly, triggering a WARN there wrt. the DSC decompression AUX device. Fix the above by moving the DSC state readout to a new DP connector specific sync_state() hook. This is anyway the logical place to update the connector object's state vs. the connector's atomic state.

2024-03-06drm/i915/selftests: Fix dependency of some timeouts on HZJanusz Krzysztofik1-2/+4
Third argument of i915_request_wait() accepts a timeout value in jiffies. Most users pass either a simple HZ based expression, or a result of msecs_to_jiffies(), or MAX_SCHEDULE_TIMEOUT, or a very small number not exceeding 4 if applicable as that value. However, there is one user -- intel_selftest_wait_for_rq() -- that passes a WAIT_FOR_RESET_TIME symbol, defined as a large constant value that most probably represents a desired timeout in ms. While that usage results in the intended value of timeout on usual x86_64 kernel configurations, it is not portable across different architectures and custom kernel configs. Rename the symbol to clearly indicate intended units and convert it to jiffies before use.

2024-03-05drm/udl: Add ARGB8888 as a formatDouglas Anderson1-0/+1
Even though the UDL driver converts to RGB565 internally (see pixel32_to_be16() in udl_transfer.c), it advertises XRGB8888 for compatibility. Let's add ARGB8888 to that list. This makes UDL devices work on ChromeOS again after commit c91acda3a380 ("drm/gem: Check for valid formats"). Prior to that commit things were "working" because we'd silently treat the ARGB8888 that ChromeOS wanted as XRGB8888.

2024-03-05drm/i915: Don't explode when the dig port we don't have an AUX CHVille Syrjälä1-3/+14
The icl+ power well code currently assumes that every AUX power well maps to an encoder which is using said power well. That is by no menas guaranteed as we: - only register encoders for ports declared in the VBT - combo PHY HDMI-only encoder no longer get an AUX CH since commit 9856308c94ca ("drm/i915: Only populate aux_ch if really needed") However we have places such as intel_power_domains_sanitize_state() that blindly traverse all the possible power wells. So these bits of code may very well encounbter an aux power well with no associated encoder. In this particular case the BIOS seems to have left one AUX power well enabled even though we're dealing with a HDMI only encoder on a combo PHY. We then proceed to turn off said power well and explode when we can't find a matching encoder. As a short term fix we should be able to just skip the PHY related parts of the power well programming since we know this situation can only happen with combo PHYs. Another option might be to go back to always picking an AUX CH for all encoders. However I'm a bit wary about that since we might in theory end up conflicting with the VBT AUX CH assignment. Also that wouldn't help with encoders not declared in the VBT, should we ever need to poke the corresponding power wells. Longer term we need to figure out what the actual relationship is between the PHY vs. AUX CH vs. AUX power well. Currently this is entirely unclear.

While at it also reduce the BUG_ON() into WARN_ON(). Then instead of a random bit pattern use 0 as default value for the number of dw skipped, this way it's not mandatory any more to patch the conditional execution.

If drm_kms_helper_poll=n the output poll work will only get scheduled from drm_helper_probe_single_connector_modes() to handle a delayed hotplug event. Since polling is disabled the work in this case should just call drm_kms_helper_hotplug_event() w/o detecting the state of connectors and rescheduling the work. After commit d33a54e3991d after a delayed hotplug event above the connectors did get re-detected in the poll work and the work got re-scheduled periodically (since poll_running is also false if drm_kms_helper_poll=n), in effect ignoring the drm_kms_helper_poll=n kernel param.

Starting in DP v1.2, the hardware documents require the use of peripheral flush mode for SDP packets such as PPS OR VSC SDP packets. In-line with this guidance, lets program the DP controller to use peripheral flush mode starting DP v1.2 Changes in v4: - Clear up that DP_MAINLINK_CTRL_FLUSH_MODE register requires the use of bits [24:23] - Modify macros DP_MAINLINK_FLUSH_MODE_UPDATE_SDP and DP_MAINLINK_FLUSH_MODE_SDP_PERIPH_UPDATE to explicitly set their values in the bits of DP_MAINLINK_CTRL_FLUSH_MODE_MASK Changes in v3: - Clear up that the DP_MAINLINK_FLUSH_MODE_SDE_PERIPH_UPDATE macro is setting bits [24:23] to a value of 3 Changes in v2: - Use the original dp_catalog_hw_revision() function to correctly check the DP HW version Signed-off-by: Paloma Arellano <[email protected]> Reviewed-by: Dmitry Baryshkov <[email protected]> Patchwork: https://patchwork.freedesktop.org/patch/579621/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Baryshkov <[email protected]>

2024-03-04drm/msm/dp: add VSC SDP support for YUV420 over DPPaloma Arellano7-0/+195
Add support to pack and send the VSC SDP packet for DP. This therefore allows the transmision of format information to the sinks which is needed for YUV420 support over DP. Changes in v5: - Slightly modify use of drm_dp_vsc_sdp_pack() - Remove dp_catalog NULL checks - Modify dp_utils_pack_sdp_header() to more clearly pack the header buffer - Move dp_utils_pack_sdp_header() inside of dp_catalog_panel_send_vsc_sdp to clearly show the relationship between the header buffer and the vsc_sdp struct - Due to the last point, remove the dp_utils_pack_vsc_sdp() function and only call drm_dp_vsc_sdp_pack() in dp_panel_setup_vsc_sdp_yuv_420() Changes in v4: - Remove struct msm_dp_sdp_with_parity - Use dp_utils_pack_sdp_header() to pack the SDP header and parity bytes into a buffer - Use this buffer when writing the VSC SDP data in dp_catalog_panel_send_vsc_sdp() - Write to all of the MMSS_DP_GENERIC0 registers instead of just the ones with non-zero values Changes in v3: - Create a new struct, msm_dp_sdp_with_parity, which holds the packing information for VSC SDP - Use drm_dp_vsc_sdp_pack() to pack the data into the new msm_dp_sdp_with_parity struct instead of specifically packing for YUV420 format - Modify dp_catalog_panel_send_vsc_sdp() to send the VSC SDP data using the new msm_dp_sdp_with_parity struct Changes in v2: - Rename GENERIC0_SDPSIZE macro to GENERIC0_SDPSIZE_VALID - Remove dp_sdp from the dp_catalog struct since this data is being allocated at the point used - Create a new function in dp_utils to pack the VSC SDP data into a buffer - Create a new function that packs the SDP header bytes into a buffer. This function is made generic so that it can be utilized by dp_audio header bytes into a buffer - Create a new function in dp_utils that takes the packed buffer and writes to the DP_GENERIC0_* registers - Split the dp_catalog_panel_config_vsc_sdp() function into two to disable/enable sending VSC SDP packets - Check the DP HW version using the original useage of dp_catalog_hw_revision() and correct the version checking logic - Rename dp_panel_setup_vsc_sdp() to dp_panel_setup_vsc_sdp_yuv_420() to explicitly state that currently VSC SDP is only being set up to support YUV420 modes Signed-off-by: Paloma Arellano <[email protected]> Reviewed-by: Dmitry Baryshkov <[email protected]> Patchwork: https://patchwork.freedesktop.org/patch/579636/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Baryshkov <[email protected]>
2024-03-04drm/msm/dp: move parity calculation to dp_utilsPaloma Arellano4-87/+112
Parity calculation is necessary for VSC SDP implementation. Therefore create new files dp_utils.c and dp_utils.h and move the parity calculating functions here. This ensures that they are usable by SDP programming in both dp_catalog.c and dp_audio.c Changes in v3: - Change ordering of the header byte macros Changes in v2: - Create new files dp_utils.c and dp_utils.h - Move the parity calculation to these new files instead of having them in dp_catalog.c and dp_catalog.h Signed-off-by: Paloma Arellano <[email protected]> Reviewed-by: Dmitry Baryshkov <[email protected]> Patchwork: https://patchwork.freedesktop.org/patch/579617/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Baryshkov <[email protected]>
