Linux kernel source tree
5cd894e258
Handles everything that's not related to the FW, the MMU or the scheduler. This is the block dealing with the GPU property retrieval, the GPU block power on/off logic, and some global operations, like global cache flushing. v6: - Add Maxime's and Heiko's acks v5: - Fix GPU_MODEL() kernel doc - Fix test in panthor_gpu_block_power_off() - Add Steve's R-b v4: - Expose CORE_FEATURES through DEV_QUERY v3: - Add acks for the MIT/GPL2 relicensing - Use macros to extract GPU ID info - Make sure we reset clear pending_reqs bits when wait_event_timeout() times out but the corresponding bit is cleared in GPU_INT_RAWSTAT (can happen if the IRQ is masked or HW takes to long to call the IRQ handler) - GPU_MODEL now takes separate arch and product majors to be more readable. - Drop GPU_IRQ_MCU_STATUS_CHANGED from interrupt mask. - Handle GPU_IRQ_PROTM_FAULT correctly (don't output registers that are not updated for protected interrupts). - Minor code tidy ups Cc: Alexey Sheplyakov <asheplyakov@basealt.ru> # MIT+GPL2 relicensing Co-developed-by: Steven Price <steven.price@arm.com> Signed-off-by: Steven Price <steven.price@arm.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Steven Price <steven.price@arm.com> # MIT+GPL2 relicensing,Arm Acked-by: Grant Likely <grant.likely@linaro.org> # MIT+GPL2 relicensing,Linaro Acked-by: Boris Brezillon <boris.brezillon@collabora.com> # MIT+GPL2 relicensing,Collabora Reviewed-by: Steven Price <steven.price@arm.com> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20240229162230.2634044-5-boris.brezillon@collabora.com |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
