2024-04-26drm/amd/display: Fix division by zero in setup_dsc_configJose Fernandez
When slice_height is 0, the division by slice_height in the calculation of the number of slices will cause a division by zero driver crash. This leaves the kernel in a state that requires a reboot. This patch adds a check to avoid the division by zero. The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor connected via Thunderbolt. The amdgpu driver crashed with this exception when I rebooted the system with the monitor connected. kernel: ? die (arch/x86/kernel/dumpstack.c:421 arch/x86/kernel/dumpstack.c:434 arch/x86/kernel/dumpstack.c:447) kernel: ? do_trap (arch/x86/kernel/traps.c:113 arch/x86/kernel/traps.c:154) kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu kernel: ? do_error_trap (./arch/x86/include/asm/traps.h:58 arch/x86/kernel/traps.c:175) kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu kernel: ? exc_divide_error (arch/x86/kernel/traps.c:194 (discriminator 2)) kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu kernel: ? asm_exc_divide_error (./arch/x86/include/asm/idtentry.h:548) kernel: ? setup_dsc_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1053) amdgpu kernel: dc_dsc_compute_config (drivers/gpu/drm/amd/amdgpu/../display/dc/dsc/dc_dsc.c:1109) amdgpu After applying this patch, the driver no longer crashes when the monitor is connected and the system is rebooted.

2024-04-26drm/amdgpu: Fix snprintf buffer size in smu_v14_0_init_microcodeSrinivasan Shanmugam
This commit addresses buffer overflow in the smu_v14_0_init_microcode function. The issue was about the snprintf function writing more bytes into the fw_name buffer than it can hold. The line of code is: snprintf(fw_name, sizeof(fw_name), "amdgpu/%s.bin", ucode_prefix); Here, snprintf is used to write a formatted string into fw_name. The format is "amdgpu/%s.bin", where %s is a placeholder for the string ucode_prefix. The sizeof(fw_name) argument tells snprintf the maximum number of bytes it can write into fw_name, including the null-terminating character. In the original code, fw_name is an array of 30 characters. The string "amdgpu/%s.bin" could be up to 41 bytes long, which exceeds the 30 bytes allocated for fw_name. This is because %s could be replaced by ucode_prefix, which can be up to 29 characters long. Adding the 12 characters from "amdgpu/" and ".bin", the total length could be 41 characters. To address this, the size of ucode_prefix has been reduced to 15 characters. This ensures that the maximum length of the string written into fw_name does not exceed its capacity. smu_13/14 etc. don't follow legacy scheme ie., amdgpu_ucode_legacy_naming Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu14/smu_v14_0.c: In function ‘smu_v14_0_init_microcode’: drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu14/smu_v14_0.c:80:52: warning: ‘%s’ directive output may be truncated writing up to 29 bytes into a region of size 23 [-Wformat-truncation=] 80 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s.bin", ucode_prefix); | ^~ ~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu14/smu_v14_0.c:80:9: note: ‘snprintf’ output between 12 and 41 bytes into a destination of size 30 80 | snprintf(fw_name, sizeof(fw_name), "amdgpu/%s.bin", ucode_prefix); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fixes: fe6cd9152464 ("drm/amd/swsmu: add smu14 ip support") Cc: Li Ma <li.ma@amd.com> Cc: Likun Gao <Likun.Gao@amd.com> Cc: Lijo Lazar <lijo.lazar@amd.com> Cc: Kenneth Feng <kenneth.feng@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Suggested-by: Lijo Lazar <lijo.lazar@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2024-04-26drm/amd/pm: Restore config space after resetLijo Lazar
During mode-2 reset, pci config space registers are affected at device side. However, certain platforms have switches which assign virtual BAR addresses and returns the same even after device is reset. This affects pci_restore_state() as it doesn't issue another config write, if the value read is same as the saved value. Add a workaround to write saved config space values from driver side. Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence restrict the workaround only to those.

2024-04-25drm/{i915, xe}: Implement fbdev emulation as in-kernel clientThomas Zimmermann
Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to intel_fbdev_setup() after i915 has registered its DRM device. Just like similar code in other drivers, i915 fbdev emulation now acts like a regular DRM client. Do the same for xe. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_client_dev_unregister() releases all in-kernel clients automatically. No further action is required within i915. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. Do the same for xe and remove its call to intel_fbdev_fini(). v8: - setup client in intel_display_driver_register (Jouni) - mention xe in commit message v7: - update xe driver - reword commit message v6: - use 'i915' for i915 device (Jouni) - remove unnecessary code for non-atomic mode setting (Jouni, Ville) - fix function name in commit message (Jouni) v3: - as before, silently ignore devices without displays v2: - let drm_client_register() handle initial hotplug - fix driver name in error message (Jani) - fix non-fbdev build (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409081029.17843-7-tzimmermann@suse.de Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2024-04-25drm/{i915,xe}: Implement fbdev client callbacksThomas Zimmermann
Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Fox xe, remove xe_display_last_close(), which restored the fbdev display. As with i915, the DRM core's drm_lastclose() performs this operation automatically. v8: - mention xe in commit message v7: - update xe driver v6: - return errors from client callbacks (Jouni) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409081029.17843-6-tzimmermann@suse.de Signed-off-by: Jani Nikula <jani.nikula@intel.com>
