[RFC 0/3] drm/amd/display: Introduce KUnit to Display Mode Library
by Maíra Canal 22 Jun '22

22 Jun '22

This RFC is a preview of the work being developed by Isabella Basso [1], Maíra Canal [2], and Tales Lelo [3], as part of their Google Summer of Code projects [4], and Magali Lemes [5], as part of her capstone project. Our main goal is to bring unit testing to the AMDPGU driver; in particular, we'll focus on the Display Mode Library (DML) for DCN2.0 and some of the DCE functions. The modern AMD Linux kernel graphics driver is the single largest driver in the mainline Linux codebase [6]. As AMD releases new GPU models, the size of AMDGPU drivers is only becoming even larger. Assuring the drivers' quality and reliability becomes a complex task without systematic testing, especially for graphic drivers - which usually involve tons of complex calculations. Also, keeping bugs away becomes an increasingly hard task with the introduction of new code. Moreover, developers might want to refactor old code without fear of the introduction of new issues. In that sense, it is possible to argue for the benefits of implementing unit testing at the AMDGPU drivers. This implementation will help developers to recognize bugs before they are merged into the mainline and also makes it possible for future code refactors of the AMDGPU driver. When analyzing the AMDGPU driver, a particular part of the driver highlights itself as a good candidate for the implementation of unit tests: the Display Mode Library (DML), as it is focused on mathematical operations. For the implementation of the tests, we decided to go with the Kernel Unit Testing Framework (KUnit). KUnit makes it possible to run test suites on kernel boot or load the tests as a module. It reports all test case results through a TAP (Test Anything Protocol) in the kernel log. Moreover, KUnit unifies the test structure and provides tools to simplify the testing for developers and CI systems. That said, we developed a little snippet on what we intend to develop in our summer. We planned the basic structure on how the tests will be introduced into the codebase and, on the concern of the CI systems, developed a structure where the unit tests can be introduced as modules and run on IGT (the IGT patch will be introduced soon). The way the modules are implemented might seem a little unusual for KUnit developers. We need to call the KUnit init function inside the AMDGPU stack, otherwise, the test won't compile as a module. So, the solution to this problem was based on the unit tests for the Thunderbolt driver, which uses KUnit and also tests a physical driver. As kunit_test_suites() defines itself as an init_module(), it conflicts with the existing one at amdgpu_drv. So, if we use kunit_test_suites(), we won't be able to compile the tests as modules and, therefore, won't be able to use IGT to run the tests. This problem with kunit_test_suites() was already discussed in the KUnit mailing list, as can be seen in [7]. The first patch configures the basic structure of the KUnit Tests, setting the proper Makefile, Kconfig, and init function. It also contains a simple test involving DML logging, which is the pretext for building the testing structure. The second patch adds KUnit tests to bw_fixed functions. This patch represents what we intend to do on the rest of the DML modules: systematic testing of the public functions of the DML, especially mathematically complicated functions. Also, it shows how simple it is to add new tests to the DML with the structure we built. Any feedback or ideas for the project are welcome!

[PATCH V2 0/2] Add Xilinx DSI-Tx subsystem DRM driver
by Venkateshwar Rao Gannavarapu 22 Jun '22

22 Jun '22

MIPI DSI TX subsystem allows you to quickly create systems based on the MIPI protocol. It interfaces between the video processing subsystems and MIPI-based displays. An internal high-speed physical layer design, D-PHY, is provided to allow direct connection to display peripherals. The subsystem consists of the following sub-blocks: - MIPI D-PHY - MIPI DSI TX Controller - AXI Crossbar Please refer pg238 [1]. The DSI TX Controller receives stream of image data through an input stream interface. At design time, this subsystem can be configured to number of lanes and pixel format. This patch series adds the dt-binding and DRM driver for Xilinx DSI-Tx soft IP. Changes in V2: - Rebased on 5.19 kernel - Moved mode_set functionality to atomic_enable as its deprecrated - Mask fixes - Replaced panel calls with bridge API's - Added mandatory atomic operations - Removed unnecessary logging - Added ARCH_ZYNQMP dependency in Kconfig - Fixed YAML warnings - Cleanup Venkateshwar Rao Gannavarapu (2): dt-bindings: display: xlnx: Add DSI 2.0 Tx subsystem documentation drm: xlnx: dsi: Add Xilinx MIPI DSI-Tx subsystem driver .../bindings/display/xlnx/xlnx,dsi-tx.yaml | 101 +++++ drivers/gpu/drm/xlnx/Kconfig | 12 + drivers/gpu/drm/xlnx/Makefile | 1 + drivers/gpu/drm/xlnx/xlnx_dsi.c | 429 +++++++++++++++++++++ 4 files changed, 543 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/xlnx/xlnx,dsi-tx.yaml create mode 100644 drivers/gpu/drm/xlnx/xlnx_dsi.c -- 1.8.3.1

[PATCH v2] drm/msm/dp: reset drm_dev to NULL at dp_display_unbind()
by Kuogee Hsieh 22 Jun '22

22 Jun '22

During msm initialize phase, dp_display_unbind() will be called to undo initializations had been done by dp_display_bind() previously if there is error happen at msm_drm_bind. Under this kind of circumstance, drm_device may not be populated completed which causes system crash at drm_dev_dbg(). This patch reset drm_dev to NULL so that following drm_dev_dbg() will not refer to any internal fields of drm_device to prevent system from crashing.

Using generic fbdev helpers breaks hibernation
by Alex Deucher 22 Jun '22

22 Jun '22

Maybe someone more familiar with the generic drm fbdev helpers can help me understand why they don't work with hibernation, at least with AMD GPUs. We converted amdgpu to use the generic helpers instead of rolling our own in this patch[1], but it seems to have broken hibernation[2]. amdgpu has always set mode_config.prefer_shadow = 1, but that seems to be the cause of the hibernation breakage with the generic helpers. I've been staring at the code for a while now but I can't see why this fails. Any pointers? Thanks, Alex [1] - https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… [2] - https://bugzilla.kernel.org/show_bug.cgi?id=216119
