2025-01-13accel/amdxdna: Remove casting mailbox payload pointerLizhi Hou
The mailbox payload pointer is void __iomem *. Casting it to u32 * is incorrect and causes sparse warning. cast removes address space '__iomem' of expression Fixes: b87f920b9344 ("accel/amdxdna: Support hardware mailbox") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202501130921.ktqwsMLH-lkp@intel.com/ Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Reviewed-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250113182617.1256094-1-lizhi.hou@amd.com
2024-11-22accel/amdxdna: Add error handlingLizhi Hou
When there is a hardware error, the NPU firmware notifies the host through a mailbox message. The message includes details of the error, such as the tile and column indexes where the error occurred. The driver starts a thread to handle the NPU error message. The thread stops the clients which are using the column where error occurred. Then the driver resets that column.
