2021-01-19drm/dp: Revert "drm/dp: Introduce EDID-based quirks"Lyude Paul1-18/+3
This reverts commit 0883ce8146ed6074c76399f4e70dbed788582e12. Originally these quirks were added because of the issues with using the eDP backlight interfaces on certain laptop panels, which made it impossible to properly probe for DPCD backlight support without having a whitelist for panels that we know have working VESA backlight control interfaces over DPCD. As well, it should be noted it was impossible to use the normal sink OUI for recognizing these panels as none of them actually filled out their OUIs, hence needing to resort to checking EDIDs. At the time we weren't really sure why certain panels had issues with DPCD backlight controls, but we eventually figured out that there was a second interface that these problematic laptop panels actually did work with and advertise properly: Intel's proprietary backlight interface for HDR panels. So far the testing we've done hasn't brought any panels to light that advertise this interface and don't support it properly, which means we finally have a real solution to this problem. As a result, we now have no need for the force DPCD backlight quirk, and furthermore this also removes the need for any kind of EDID quirk checking in DRM. So, let's just revert it for now since we were the only driver using this. v3: * Rebase v2: * Fix indenting error picked up by checkpatch in intel_edp_init_connector() Signed-off-by: Lyude Paul <[email protected]> Acked-by: Jani Nikula <[email protected]> Cc: [email protected] Cc: Vasily Khoruzhick <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

git://anongit.freedesktop.org/drm/drm-intel into drm-next Add support for DP-HDMI2.1 PCON From the series cover letter: This patch series attempts to add support for a DP-HDMI2.1 Protocol Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata E5 to DisplayPort_v2.0: https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299 The details are mentioned in: VESA DP-to-HDMI PCON Specification Standalone Document https://groups.vesa.org/wg/DP/document/15651 This series starts with adding support for FRL (Fixed Rate Link) Training between the PCON and HDMI2.1 sink. As per HDMI2.1 specification, a new data-channel or lane is added in FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4 lanes). With these patches, the HDMI2.1 PCON can be configured to achieve FRL training based on the maximum FRL rate supported by the panel, source and the PCON. The approach is to add the support for FRL training between PCON and HDMI2.1 sink and gradually add other blocks for supporting higher resolutions and other HDMI2.1 features, that can be supported by pcon for the sources that do not natively support HDMI2.1. This is done before the DP Link training between the source and PCON is started. In case of FRL training is not achieved, the PCON will work in the regular TMDS mode, without HDMI2.1 feature support. Any interruption in FRL training between the PCON and HDMI2.1 sink is notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD registers are read and FRL training is re-attempted. Currently, we have tested the FRL training and are able to enable 4K display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting panel.

2021-01-05drm: Use a const drm_driver for legacy PCI devicesLaurent Pinchart2-8/+6
Now that the legacy PCI support code doesn't need to write to the drm_driver structure, it can be treated as const through the whole DRM core, unconditionally. This allows declaring the structure as const in all drivers, removing one possible attack vector. Signed-off-by: Laurent Pinchart <[email protected]> Reviewed-by: Daniel Vetter <[email protected]>
2021-01-05drm: Move legacy device list out of drm_driverLaurent Pinchart2-9/+3
The drm_driver structure contains a single field (legacy_dev_list) that is modified by the DRM core, used to store a linked list of legacy DRM devices associated with the driver. In order to make the structure const, move the field out to a global variable. This requires locking access to the global where the local field didn't require serialization, but this only affects legacy drivers, and isn't in any hot path. While at it, compile-out the legacy_dev_list field when DRM_LEGACY isn't defined.

2021-01-05drm: Add default modes for connectors in unknown stateLaurent Pinchart1-1/+7
The DRM CRTC helpers add default modes to connectors in the connected state if no mode can be retrieved from the connector. This behaviour is useful for VGA or DVI outputs that have no connected DDC bus. However, in such cases, the status of the output usually can't be retrieved and is reported as connector_status_unknown. Extend the addition of default modes to connectors in an unknown state to support outputs that can retrieve neither the modes nor the connection status.

2020-12-22drm/dp_helper: Add support for link failure detectionSwati Sharma1-0/+17
There are specific DPCDs defined for detecting link failures between the PCON and HDMI sink and check the link status. In case of link failure, PCON will communicate the same using an IRQ_HPD to source. HDMI sink would have indicated the same to PCON using SCDC interrupt mechanism. While source can always read final HDMI sink's status using I2C over AUX, it is easier and faster to read the PCONs already read HDMI sink status registers. This patch adds the DPCDs required for link failure detection and provide a helper function for printing error count/lane which might help in debugging the link failure issues. v2: Addressed comments from Uma Shankar: -rephrased the commit message, as per the code. -fixed styling issues -added documentation for the helper function.

2020-12-15drm: Introduce an atomic_commit_setup functionMaxime Ripard1-0/+21
Private objects storing a state shared across all CRTCs need to be carefully handled to avoid a use-after-free issue. The proper way to do this to track all the commits using that shared state and wait for the previous commits to be done before going on with the current one to avoid the reordering of commits that could occur. However, this commit setup needs to be done after drm_atomic_helper_setup_commit(), because before the CRTC commit structure hasn't been allocated before, and before the workqueue is scheduled, because we would be potentially reordered already otherwise. That means that drivers currently have to roll their own drm_atomic_helper_commit() function, even though it would be identical if not for the commit setup. Let's introduce a hook to do so that would be called as part of drm_atomic_helper_commit, allowing us to reuse the atomic helpers.

Rename "ring_mirror_list" to "pending_list", to describe what something is, not what it does, how it's used, or how the hardware implements it. This also abstracts the actual hardware implementation, i.e. how the low-level driver communicates with the device it drives, ring, CAM, etc., shouldn't be exposed to DRM. The pending_list keeps jobs submitted, which are out of our control. Usually this means they are pending execution status in hardware, but the latter definition is a more general (inclusive) definition.

2020-12-08drm/scheduler: "node" --> "list"Luben Tuikov1-2/+2
Rename "node" to "list" in struct drm_sched_job, in order to make it consistent with what we see being used throughout gpu_scheduler.h, for instance in struct drm_sched_entity, as well as the rest of DRM and the kernel.

2020-12-05drm: Remove drmm_add_final_kfree() declaration from public headersLaurent Pinchart1-2/+0
The drmm_add_final_kfree() function is declared in the include/drm/drm_managed.h public header, but has become an internal API not exposed to drivers. Drop it from drm_managed.h as it's already declared in drm_internal.h.

2020-11-30drm/prime: split array import functions v4Christian König1-3/+4
Mapping the imported pages of a DMA-buf into an userspace process doesn't work as expected. But we have reoccurring requests on this approach, so split the functions for this and document that dma_buf_mmap() needs to be used instead. v2: split it into two functions v3: rebased on latest changes v4: update commit message a bit Signed-off-by: Christian König <[email protected]> Acked-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/403838/

2020-11-30drm/cma-helper: Implement mmap as GEM CMA object functionsThomas Zimmermann1-7/+3
The new GEM object function drm_gem_cma_mmap() sets the VMA flags and offset as in the old implementation and immediately maps in the buffer's memory pages. Changing CMA helpers to use the GEM object function allows for the removal of the special implementations for mmap and gem_prime_mmap callbacks. The regular functions drm_gem_mmap() and drm_gem_prime_mmap() are now used.

Not technically a problem for ttm, but very likely a driver bug and pretty big time confusing for reviewing code. So warn about it, both at cleanup time (so we catch these for sure) and at pin/unpin time (so we know who's the culprit).
