2024-07-12drm/omap: Restrict compile testing to PAGE_SIZE less than 64KBNathan Chancellor1-1/+1
Prior to commit dc6fcaaba5a5 ("drm/omap: Allow build with COMPILE_TEST=y"), it was only possible to build the omapdrm driver with a 4KB page size. After that change, when the PAGE_SIZE is 64KB or larger, clang points out that the driver has some assumptions around the page size implicitly by passing PAGE_SIZE to a parameter with a type of u16: drivers/gpu/drm/omapdrm/omap_gem.c:758:7: error: implicit conversion from 'unsigned long' to 'u16' (aka 'unsigned short') changes value from 65536 to 0 [-Werror,-Wconstant-conversion] 757 | block = tiler_reserve_2d(fmt, omap_obj->width, omap_obj->height, | ~~~~~~~~~~~~~~~~ 758 | PAGE_SIZE); | ^~~~~~~~~ arch/powerpc/include/asm/page.h:25:34: note: expanded from macro 'PAGE_SIZE' 25 | #define PAGE_SIZE (ASM_CONST(1) << PAGE_SHIFT) | ~~~~~~~~~~~~~^~~~~~~~~~~~~ drivers/gpu/drm/omapdrm/omap_gem.c:1504:44: error: implicit conversion from 'unsigned long' to 'u16' (aka 'unsigned short') changes value from 65536 to 0 [-Werror,-Wconstant-conversion] 1504 | block = tiler_reserve_2d(fmts[i], w, h, PAGE_SIZE); | ~~~~~~~~~~~~~~~~ ^~~~~~~~~ arch/powerpc/include/asm/page.h:25:34: note: expanded from macro 'PAGE_SIZE' 25 | #define PAGE_SIZE (ASM_CONST(1) << PAGE_SHIFT) | ~~~~~~~~~~~~~^~~~~~~~~~~~~ 2 errors generated. As there is a lot of use of a u16 type throughout this driver and it will only ever be run on hardware that has a 4KB page size, just restrict compile testing to when the page size is less than 64KB (as no other issues have been discussed and it keeps compile testing relatively more available).

This is wrong and was caused by the quite confusing PCI devres API in which some, but not all, functions become managed that way. The function pci_iomap_range() is never managed.

2024-07-11drm/xe: Use write-back caching mode for system memory on DGFXThomas Hellström2-20/+30
The caching mode for buffer objects with VRAM as a possible placement was forced to write-combined, regardless of placement. However, write-combined system memory is expensive to allocate and even though it is pooled, the pool is expensive to shrink, since it involves global CPU TLB flushes. Moreover write-combined system memory from TTM is only reliably available on x86 and DGFX doesn't have an x86 restriction. So regardless of the cpu caching mode selected for a bo, internally use write-back caching mode for system memory on DGFX. Coherency is maintained, but user-space clients may perceive a difference in cpu access speeds. v2: - Update RB- and Ack tags. - Rephrase wording in xe_drm.h (Matt Roper) v3: - Really rephrase wording.

2024-07-11drm/fb-helper: Don't schedule_work() to flush frame buffer during panic()Qiuxu Zhuo1-0/+11
Sometimes the system [1] hangs on x86 I/O machine checks. However, the expected behavior is to reboot the system, as the machine check handler ultimately triggers a panic(), initiating a reboot in the last step. The root cause is that sometimes the panic() is blocked when drm_fb_helper_damage() invoking schedule_work() to flush the frame buffer. This occurs during the process of flushing all messages to the frame buffer driver as shown in the following call trace: Machine check occurs [2]: panic() console_flush_on_panic() console_flush_all() console_emit_next_record() con->write() vt_console_print() hide_cursor() vc->vc_sw->con_cursor() fbcon_cursor() ops->cursor() bit_cursor() soft_cursor() info->fbops->fb_imageblit() drm_fbdev_generic_defio_imageblit() drm_fb_helper_damage_area() drm_fb_helper_damage() schedule_work() // <--- blocked here ... emergency_restart() // wasn't invoked, so no reboot. During panic(), except the panic CPU, all the other CPUs are stopped. In schedule_work(), the panic CPU requires the lock of worker_pool to queue the work on that pool, while the lock may have been token by some other stopped CPU. So schedule_work() is blocked. Additionally, during a panic(), since there is no opportunity to execute any scheduled work, it's safe to fix this issue by skipping schedule_work() on 'oops_in_progress' in drm_fb_helper_damage(). [1] Enable the kernel option CONFIG_FRAMEBUFFER_CONSOLE, CONFIG_DRM_FBDEV_EMULATION, and boot with the 'console=tty0' kernel command line parameter. [2] Set 'panic_timeout' to a non-zero value before calling panic().

2024-07-10drm/amdgpu: timely save bad pages to eeprom after gpu ras reset is completedYiPeng Chai2-1/+23
The problem case is as follows: 1. GPU A triggers a gpu ras reset, and GPU A drives GPU B to also perform a gpu ras reset. 2. After gpu B ras reset started, gpu B queried a DE data. Since the DE data was queried in the ras reset thread instead of the page retirement thread, bad page retirement work would not be triggered. Then even if all gpu resets are completed, the bad pages will be cached in RAM until GPU B's bad page retirement work is triggered again and then saved to eeprom. This patch can save the bad pages to eeprom in time after gpu ras reset is completed. v2: 1. Add the above description to code comments. 2. Reuse existing function.

2024-07-10drm/amd/pm: Ignore initial value in smu response registerDanijel Slivka3-5/+40
Why: If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver load or driver unload, subsequent amdgpu driver load will fail at smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean environment is 0x1 and if value differs from expected, amdgpu driver load will fail. How to fix: Ignore the initial value in smu response register before the first smu message is sent,if smc in SMU_FW_INIT state, just proceed further to send the message. If register holds an unexpected value after smu message was sent set, smc_state to SMU_FW_HANG state and no further smu messages will be sent. v2: Set SMU_FW_INIT state at the start of smu hw_init/resume. Check smc_fw_state before sending smu message if in hang state skip sending message. Set SMU_FW_HANG only in case unexpected value is detected Signed-off-by: Danijel Slivka <[email protected]> Reviewed-by: Kenneth Feng <[email protected]> Reviewed-by: Lijo Lazar <[email protected]> Reviewed-by: Asad Kamal <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
