When runtime resume re-enables the clock, this\nmay result in a mismatch between the rail voltage and the clock rate.\n\nFor example, in the DPU bind path, the sequence could be:\n cpu0: dev_sync_state -> rpmhpd_sync_state\n cpu1: dpu_kms_hw_init\ntimeline 0 ------------------------------------------------> t\n\nAfter rpmhpd_sync_state, the voltage performance is no longer guaranteed\nto stay at the highest level. During dpu_kms_hw_init, calling\ndev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to\nfall to MIN_SVS while the core clock is still at its maximum frequency.\nWhen the power is re-enabled, only the clock is enabled, leading to a\nsituation where the MMCX rail is at MIN_SVS but the core clock is at its\nhighest rate. In this state, the rail cannot sustain the clock rate,\nwhich may cause instability or system crash.\n\nRemove the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend\nto ensure the correct vote is restored when DPU resumes.\n\nPatchwork: https://patchwork.freedesktop.org/patch/710077/"}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c"], "versions": [{"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "1181a7028d37e0b1e720a36125a03f5db97e3d27", "status": "affected", "versionType": "git"}, {"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "9830999c9e065c1813ec5435bfe4eab98ee54a87", "status": "affected", "versionType": "git"}, {"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "c5735c7d0eef7a5240f9c1c66e44ba52a1be58d6", "status": "affected", "versionType": "git"}, {"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "0f7dd5839cfabaf9c007fb718ec66e907a473c93", "status": "affected", "versionType": "git"}, {"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "0ccf4f27b4652570b5de3de02a89a86435559de9", "status": "affected", "versionType": "git"}, {"version": "b0530eb1191307e9038d75e5c83973a396137681", "lessThan": "bc1dccc518cc5ab5140fba06c27e7188e0ed342b", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c"], "versions": [{"version": "5.9", "status": "affected"}, {"version": "0", "lessThan": "5.9", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.175", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.141", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.91", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.33", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.10", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "6.1.175"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "6.6.141"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "6.12.91"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "6.18.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.9", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/1181a7028d37e0b1e720a36125a03f5db97e3d27"}, {"url": "https://git.kernel.org/stable/c/9830999c9e065c1813ec5435bfe4eab98ee54a87"}, {"url": "https://git.kernel.org/stable/c/c5735c7d0eef7a5240f9c1c66e44ba52a1be58d6"}, {"url": "https://git.kernel.org/stable/c/0f7dd5839cfabaf9c007fb718ec66e907a473c93"}, {"url": "https://git.kernel.org/stable/c/0ccf4f27b4652570b5de3de02a89a86435559de9"}, {"url": "https://git.kernel.org/stable/c/bc1dccc518cc5ab5140fba06c27e7188e0ed342b"}], "title": "drm/msm/dpu: fix mismatch between power and frequency", "x_generator": {"engine": "bippy-1.2.0"}}}}
