2025-06-09drivers: gpu: drm: msm: registers: improve reproducibilityRyan Eatmon
The files generated by gen_header.py capture the source path to the input files and the date. While that can be informative, it varies based on where and when the kernel was built as the full path is captured. Since all of the files that this tool is run on is under the drivers directory, this modifies the application to strip all of the path before drivers. Additionally it prints <stripped> instead of the date.

2025-04-18drm/msm/a6xx+: Don't let IB_SIZE overflowRob Clark
IB_SIZE is only b0..b19. Starting with a6xx gen3, additional fields were added above the IB_SIZE. Accidentially setting them can cause badness. Fix this by properly defining the CP_INDIRECT_BUFFER packet and using the generated builder macro to ensure unintended bits are not set. v2: add missing type attribute for IB_BASE v3: fix offset attribute in xml Reported-by: Connor Abbott <cwabbott0@gmail.com> Fixes: a83366ef19ea ("drm/msm/a6xx: add A640/A650 to gpulist") Signed-off-by: Rob Clark <robdclark@chromium.org> Patchwork: https://patchwork.freedesktop.org/patch/643396/

2025-02-26drm/msm/dsi/phy: Use dsi_pll_cmn_clk_cfg1_update() when registering PLLKrzysztof Kozlowski
Newly added dsi_pll_cmn_clk_cfg1_update() wrapper protects concurrent updates to PHY_CMN_CLK_CFG1 register between driver and Common Clock Framework. pll_7nm_register() still used in one place previous readl+writel, which can be simplified with this new wrapper. This is purely for readability and simplification and should have no functional impact, because the code touched here is before clock is registered via CCF, so there is no concurrency issue.

2025-02-15drm/msm/dsi/phy: Do not overwite PHY_CMN_CLK_CFG1 when choosing bitclk sourceKrzysztof Kozlowski
PHY_CMN_CLK_CFG1 register has four fields being used in the driver: DSI clock divider, source of bitclk and two for enabling the DSI PHY PLL clocks. dsi_7nm_set_usecase() sets only the source of bitclk, so should leave all other bits untouched. Use newly introduced dsi_pll_cmn_clk_cfg1_update() to update respective bits without overwriting the rest. While shuffling the code, define and use PHY_CMN_CLK_CFG1 bitfields to make the code more readable and obvious.

2025-02-15drm/msm/dsi/phy: Protect PHY_CMN_CLK_CFG1 against clock driverKrzysztof Kozlowski
PHY_CMN_CLK_CFG1 register is updated by the PHY driver and by a mux clock from Common Clock Framework: devm_clk_hw_register_mux_parent_hws(). There could be a path leading to concurrent and conflicting updates between PHY driver and clock framework, e.g. changing the mux and enabling PLL clocks. Add dedicated spinlock to be sure all PHY_CMN_CLK_CFG1 updates are synchronized. While shuffling the code, define and use PHY_CMN_CLK_CFG1 bitfields to make the code more readable and obvious.

2025-02-15drm/msm/dsi/phy: Protect PHY_CMN_CLK_CFG0 updated from driver sideKrzysztof Kozlowski
PHY_CMN_CLK_CFG0 register is updated by the PHY driver and by two divider clocks from Common Clock Framework: devm_clk_hw_register_divider_parent_hw(). Concurrent access by the clocks side is protected with spinlock, however driver's side in restoring state is not. Restoring state is called from msm_dsi_phy_enable(), so there could be a path leading to concurrent and conflicting updates with clock framework. Add missing lock usage on the PHY driver side, encapsulated in its own function so the code will be still readable. While shuffling the code, define and use PHY_CMN_CLK_CFG0 bitfields to make the code more readable and obvious.

The gen_header.py script is failing for older versions of python3 such as python 3.5. Two issues observed with python 3.5 are ... 1. Python 3 versions prior to 3.6 do not support the f-string format. 2. Early python 3 versions do not support the 'required' argument for the argparse add_subparsers().
