I'm trying to clean out the PCI bugzilla and make sure things don't languish there without attention. The following regressions are still open. 190861 v4.8-rc1 Keyboard & mouse unresponsive after locking screen https://bugzilla.kernel.org/show_bug.cgi?id=190861 Bisected to 006d44e49a25 ("PCI: Add runtime PM support for PCIe ports") Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx> 189361 v4.2 PCIe packet switch enumeration https://bugzilla.kernel.org/show_bug.cgi?id=189361 Awaiting testing on v4.9. Possibly related to d0751b98dfa3 ("PCI: Add dev->has_secondary_link to track downstream PCIe links"), which appeared in v4.2-rc1, or b35b1df5e6c2 ("PCI: Tolerate hierarchies with no Root Port"), which appeared in v4.2-rc8. 117191 v4.3 BAR allocation problems https://bugzilla.kernel.org/show_bug.cgi?id=117191 Meelis reports issues on both sparc and x86. Wonder why we haven't seen more reports of this if it affects x86. 102311 v4.1 ASPM: ASMEDA asm1062 not working https://bugzilla.kernel.org/show_bug.cgi?id=102311 Bisected to 387d37577fdd ("PCI: Don't clear ASPM bits when the FADT declares it's unsupported"), which appeared in v4.1-rc1. https://bugzilla.kernel.org/show_bug.cgi?id=189951 also bisected to 387d37577fdd. https://patchwork.ozlabs.org/patch/690339/ is a proposed patch, but I have some reservations about it. 96261 v4.0-rc1 Non-prefetchable BARs not allowed in prefetchable windows https://bugzilla.kernel.org/show_bug.cgi?id=96261 This may be legal in PCIe hierarchies because memory transactions include explicit lengths. The current behavior causes problems at least on sparc (but this isn't really arch-specific). Yinghai proposed some patches, but Ben objected to them. 85311 v3.17-rc6 PCI dmesg spam when opening lid https://bugzilla.kernel.org/show_bug.cgi?id=85311 Dmesg spam on resume, e.g., "BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment" messages. Partly fixed by 63e22924f5dc ("PCI: Mark shadow copy of VGA ROM as IORESOURCE_PCI_FIXED"). Other messages remain. 81431 v3.16 pci=realloc fails to modify bridge windows https://bugzilla.kernel.org/show_bug.cgi?id=81431 Resource assignment problem in unusual configuration. Bisected to 5b28541552ef ("PCI: Restrict 64-bit prefetchable bridge windows to 64-bit resources"), which appeared in v3.16-rc1. Not sure whether it's feasible to fix this. 42606 v2.6.36 I/O range not assigned https://bugzilla.kernel.org/show_bug.cgi?id=42606 I proposed a quirk to disable _CRS on Supermicro X8DTH-i/6/iF/6F, which is probably sufficient to resolve this bug. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
