A similar issue was fixed before\nin commit 6694482a70e9 (\"drm/msm: Avoid unclocked GMU register access in\n6xx gpu_busy\"): msm_devfreq_init() does call devfreq_suspend_device(), but\nunlike msm_devfreq_suspend(), it doesn't set the df->suspended flag\naccordingly. This means the df->suspended flag does not match the actual\ndevfreq state after initialization and msm_devfreq_get_dev_status() will\nend up accessing GMU registers, causing the crash.\n\nFix this by setting df->suspended correctly during initialization.\n\nPatchwork: https://patchwork.freedesktop.org/patch/650772/", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "6694482a70e9536efbf2ac233cbf0c302d6e2dae", "status": "affected", "versionType": "git", "lessThan": "ae2015b0dbc0eea7aaf022194371f451f784d994" }, { "version": "6694482a70e9536efbf2ac233cbf0c302d6e2dae", "status": "affected", "versionType": "git", "lessThan": "7946a10f8da75abc494e4bb80243e153e93e459a" }, { "version": "6694482a70e9536efbf2ac233cbf0c302d6e2dae", "status": "affected", "versionType": "git", "lessThan": "1847ea44e3bdf7da8ff4158bc01b43a2e46394bd" }, { "version": "6694482a70e9536efbf2ac233cbf0c302d6e2dae", "status": "affected", "versionType": "git", "lessThan": "a6f673cc9488fd722c601fe020601dba14db21b2" }, { "version": "6694482a70e9536efbf2ac233cbf0c302d6e2dae", "status": "affected", "versionType": "git", "lessThan": "b71717735be48d7743a34897e9e44a0b53e30c0e" }, { "version": "1f6c087dd6a915f1c3471f0f0f696847fc8c592f", "status": "affected", "versionType": "git" }, { "version": "9c8b3f05fb18fba12f3fca80a378c9b8f3d04cd6", "status": "affected", "versionType": "git" }, { "version": "5.18.18", "status": "affected", "versionType": "semver", "lessThan": "5.19" }, { "version": "5.19.2", "status": "affected", "versionType": "semver", "lessThan": "5.20" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "6.0", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "6.0" }, { "version": "6.1.143", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.96", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.36", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.15.5", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.15.*" }, { "version": "6.16", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
