[PATCH RFC 00/19] drm: Add support for bus-format negotiation
by Boris Brezillon 02 Dec '19

02 Dec '19

Hello, This patch series aims at adding support for runtime bus-format negotiation between all elements of the 'encoder -> bridges -> connector/display' section of the pipeline. In order to support that, we need drm bridges to fully take part in the atomic state validation process, which requires addition of a drm_bridge_state + a new drm_bridge_funcs.atomic_check() hook (patches 10 - 12). Once those basic building blocks are in place, we can add new helpers to facilitate bus-format … [View More]negotiation between element of the encoder chain (patches 13 - 14). Patches 1 to 9 are preparatory patches for patches 10 - 14. Patch 1 is needed to allow inclusion of drm_atomic.h from drm_bridge.h, which we need to make drm_bridge/drm_bridge_state inherit from drm_private_obj/drm_private_obj_state. Patches 2 to 9 are about transitioning the bridge chain to a double-linked list, which is needed to allow bridge elements to negotiate with the next and prev element in the pipeline. Most of those patches can be applied independently of the rest of the series, especially patches 2 - 7 which I think fix some misuses of the drm_bridge API. To finish, patches 15 - 17 demonstrate how bus-format negotiation can be done, and patches 18 - 19 were needed for the use case I used to test whole solution. As you've noticed, this is an RFC, so any kind of feedback is welcome (apart from checkpatch reports :P).

[PATCH 00/60] drm/omap: Replace custom display drivers with drm_bridge and drm_panel
by Laurent Pinchart 02 Dec '19

02 Dec '19

Hello, This patch series (nearly, see [1]) completes the rework of the omapdrm driver to move to drm_bridge and drm_panel. What a journey. This work was started more than a year ago, and this last piece is perhaps the one that will generate the most bikeshedding as it touches the DRM core. I'm braced for the impact, but please be gentle :-) Let's start with some context to understand the problem. omapdrm contains custom drivers for external encoders, panels and connectors (collectively … [View More]referred to as display drivers). It combines them to create output pipelines abstracted by a drm_encoder and a drm_connector, with the ability to delegate the encoder and connector operations to the component in the pipeline that implements them. For instance, for an HDMI output pipeline, the hot plug detection and the EDID read can be implemented by two different components, when they are handled by two different devices at the hardware level. DRM/KMS uses drm_bridge and drm_panel to abstract external encoders and panels. The model is however simpler than what omapdrm provides, as bridges were designed to be simple add-ons at the output of a drm_encoder. The ability to chain bridges exists, but a bridge driver hardcodes in its design its position in the pipeline : bridges that expect to terminate the pipeline create a drm_connector, while bridges that expect to be an intermediate component in the pipeline do not create a connector. In addition to not supporting bridges that can be either internal or a termination point in the pipeline depending on the hardware design, implementing the drm_connector inside a bridge driver makes it impossible to support hardware where bridge operations are handled by different hardware components, as explained above. The omapdrm driver has received support for drm_bridge and drm_panel, but these issues prevented completely moving away from the omapdrm custom display drivers. This patch series thus first reworks the drm_bridge infrastructure to support the omapdrm use cases, and then transitions the omapdrm driver. The series starts by 01/60 that adds a new flag to the drm_display_info structure to identify HDMI sinks. This is a feature needed by the OMAP4 and OMAP5 HDMI encoders, and I believe it can be useful to other HDMI encoders as well. 02/60 is then a small drive-by cleanup. The first sizeable change follows with the rename of the dumb-vga-dac driver to simple-bridge (03/60 and 04/60) and support for non-VGA bridges (05/60). This doesn't change the spirit of the driver that still focusses on transparent bridges, but prepares it to support an analog video amplifier. Patches 06/60 then add support for an enable GPIO, and 07/60 support for the OPA362 video amplifier itself. The next two patches address the drm_bridge issues explained above. Patch 08/60 makes it possible to attach to a bridge without having the bridge create a connector. The connector is expected to be created by the display controller driver. Patch 09/60 adds connector-related operations to drm_bridge to make this possible. The approach taken here is slightly intrusive as path 08/60 adds a parameter to tbe bridge .attach() operation, and thus touches all bridge drivers, even if the changes are very simple (as a consequence I haven't CC'ed all the individual bridge maintainers as the CC list was too large). Other options may be possible, what matters most to me is the feature, not so much its implementation. Please note that I envision the parameter to be removed down the road once all bridge drivers will be converted to the new model (but this will likely take time, and both models can co-exist for as long as necessary). The next six patches make use of these new features: patches 10/60 and 11/60 add new bridge drivers for display connectors and for the TI TPD12S015 HDMI level shifter respectively, patch 12/60 supports the new API in the panel bridge driver, and patches 13/60 to 15/60 do the same in the ti-tfp410 driver. The nine patches that follow add support for six new panels, with the related DT bindings (16/60 to 18/60) and the drm_panel drivers (19/60 to 24/60). The code originates from the corresponding omapdrm-specific panel drivers (which explains why only three DT patches are needed as most of the bindings are already present). Patch 25/60 is possibly the most remarkable one in the series, with the drm_bridge operations extension, as it provides a helper for display controller drivers to construct a drm_connector entirerly backed by a chain of bridges. This offsets the complexity of the additional bridge operations by handling it all in a single place. An example usage for omapdrm can be found in patch 43/60. Don't let its diffstat mislead you, usage of the helper would remove lots of code if it wasn't for the fact that the legacy implementation still has to be kept for the DSI panel (see [1]). Down the road this helper and the new operation paradigm should remove code from both display controller and bridge drivers. The rest of the series is omapdrm-focussed, slowly preparing the driver for the switch to drm_bridge drivers using the new helper (43/60), the removal of the omapdrm-specific display drivers (44/60 and 50/60), and lots of simplification and code removal in the other patches. [1] The only notable exception is the omapdrm-specific DSI panel driver that implements a large number of custom operations. This should be addressed separately.

In addition to not supporting bridges that can be either internal or a termination point in the pipeline depending on the hardware design, implementing the drm_connector inside a bridge driver makes it impossible to support hardware where bridge operations are handled by different hardware components, as explained above. The omapdrm driver has received support for drm_bridge and drm_panel, but these issues prevented completely moving away from the omapdrm custom display drivers. This patch series thus first reworks the drm_bridge infrastructure to support the omapdrm use cases, and then transitions the omapdrm driver. The series starts with a small drive-by cleanup (01/50), followed by a new helper (02/50) that leverages data from drm_connector.c to convert a connector type to a string. Patch 03/50 then adds a new flag to the drm_display_info structure to identify HDMI sinks. This is a feature needed by the OMAP4 and OMAP5 HDMI encoders, and I believe it can be useful to other HDMI encoders as well. The next two patches address the drm_bridge issues explained above. Patch 04/50 adds connector-related operations to drm_bridge, and patch 05/50 makes it possible to attach to a bridge without having the bridge create a connector. The connector is expected to be created by the display controller driver. The approach taken here is slightly intrusive as path 05/50 adds a parameter to the bridge .attach() operation, and thus touches all bridge drivers, even if the changes are very simple (as a consequence I haven't CC'ed all the individual bridge maintainers as the CC list was too large). Other options may be possible, what matters most to me is the feature, not so much its implementation. Please note that compared to v1 this version uses a flag bitmask instead of a boolean on Andrzej's request, as he expects the parameter to be useful for other purposes. The first sizeable change follows with the rename of the dumb-vga-dac driver to simple-bridge (06/50 and 07/50) and support for non-VGA bridges (08/50). This doesn't change the spirit of the driver that still focusses on transparent bridges, but prepares it to support an analog video amplifier. Patches 09/50 then add support for an enable GPIO, and 10/50 support for the OPA362 video amplifier itself. The next six patches make use of these new features: patches 11/50 and 12/50 add new bridge drivers for display connectors and for the TI TPD12S015 HDMI level shifter respectively, patch 13/50 supports the new API in the panel bridge driver, and patches 15/50 to 16/50 do the same in the ti-tfp410 driver. Patch 17/50 is possibly the most remarkable one in the series, with the drm_bridge operations extension, as it provides a helper for display controller drivers to construct a drm_connector entirerly backed by a chain of bridges. This offsets the complexity of the additional bridge operations by handling it all in a single place. An example usage for omapdrm can be found in patch 34/50. Don't let its diffstat mislead you, usage of the helper would remove lots of code if it wasn't for the fact that the legacy implementation still has to be kept for the DSI panel (see [1]). Down the road this helper and the new operation paradigm should remove code from both display controller and bridge drivers. The rest of the series is omapdrm-focussed, slowly preparing the driver for the switch to drm_bridge drivers using the new helper (34/50), the removal of the omapdrm-specific display drivers (35/50), and lots of simplification and code removal in the other patches. Compared to v1, many review comments have been taken into account, please see individual patches for details. Please note that some issues are still being discussed and have thus not been addressed yet. This includes HPD handling and removal of the drm_connector argument from the drm_bridge .get_edid() operation. The patches can be found at git://linuxtv.org/pinchartl/media.git omapdrm/bridge/devel [1] The only notable exception is the omapdrm-specific DSI panel driver that implements a large number of custom operations. This should be addressed separately.

[PATCH v1 0/16] drm: panel related updates
by Sam Ravnborg 02 Dec '19

02 Dec '19

The first 9 patches replaces direct use of the drm_panel function pointers with their drm_panel_* counterparts. The function pointers are only supposed to be used by the drm_panel infrastructure and direct use are discouraged. ili9322 is updated to handle bus_flags in get_modes like everyone else. This is in preparation for a later patch series where controller becomes an arugument to get_modes() and not like today where drm_panel is attached to a controller. The remaining patches move … [View More]functionality to the drm_panel core that today are repeated in many drivers. As preparation for this the inline functions are moved to drm_panel.c and kernel-doc is made inline. panel-simple is updated to benefit from the additional infrastructure and is an example for the simplifications that can be done. The patchset has been tested on my embedded target, and build tested. Feedback welcome! The "fix opencoded" patches are all independent and can be applied out of order. They were kept here to keep panel related patches in one series.

[DPU PATCH v3 0/5] List of patches for DP drivers on SnapDragon
by Chandan Uddaraju 02 Dec '19

02 Dec '19

These patches are to enable DisplayPort driver on SanpDragon. These patches have dependency on clock driver changes that provide DP clock support. Changes in V2: Core Dp driver: -- Update copyright markings on all relevant files. -- Change pr_err() to DRM_ERROR() -- Use APIs directly instead of function pointers. -- Use drm_display_mode structure to store link parameters in the driver. -- Use macros for register definitions instead of hardcoded values in dp_catalog.… [View More]c file. -- Replace writel_relaxed/readl_relaxed with writel/readl and remove memory barriers. -- Remove unnecessary NULL checks. -- Use drm helper functions for dpcd read/write. -- Use DRM_DEBUG_DP for debug msgs. DP PLL driver: -- Update copyright markings on all relevant files. -- Use DRM_DEBUG_DP for debug msgs. Changes in V3: Core Dp Driver: -- Removed changes in dpu_io_util.[ch] -- Added locking around "is_connected" flag and removed atomic_set() -- Removed the argument validation checks in all the static functions except initialization functions and few API calls across msm/dp files -- Removed hardcoded values for register reads/writes -- Removed vreg related generic structures. -- Added return values where ever necessary. -- Updated dp_ctrl_on function. -- Calling the ctrl specific catalog functions directly instead of function pointers. -- Added seperate change that adds standard value in drm_dp_helper file. -- Added separate change in this list that is used to initialize displayport in DPU driver. -- Added change to use drm_dp_get_adjust_request_voltage() function.
