Bjorn Helgaas 9088614323 PCI: Avoid broken MSI on SB600 USB devices ... [ Upstream commit 63cd736f44 ] Some ATI SB600 USB adapters advertise MSI, but if INTx is disabled by setting PCI_COMMAND_INTX_DISABLE, MSI doesn't work either. The PCI/PCIe specs do not require software to set PCI_COMMAND_INTX_DISABLE when enabling MSI, but Linux has done that for many years. Mick reported that 306c54d0ed ("usb: hcd: Try MSI interrupts on PCI devices") broke these devices. Prior to 306c54d0ed, they used INTx. Starting with 306c54d0ed, they use MSI, and and the fact that Linux sets PCI_COMMAND_INTX_DISABLE means both INTx and MSI are disabled on these devices. Avoid this SB600 defect by disabling MSI so we use INTx as before. Fixes: 306c54d0ed ("usb: hcd: Try MSI interrupts on PCI devices") Link: https://lore.kernel.org/r/20220321183446.1108325-1-helgaas@kernel.org Link: https://bugzilla.kernel.org/show_bug.cgi?id=215690 Link: https://lore.kernel.org/all/PxIByDyBRcsbpcmVhGSNDFAoUcMmb78ctXCkw6fbpx25TGlCHvA6SJjjFkNr1FfQZMntYPTNyvEnblxzAZ8a6jP9ddLpKeCN6Chi_2FuexU=@protonmail.com/ Link: https://lore.kernel.org/r/20220314101448.90074-1-andriy.shevchenko@linux.intel.com BugLink: https://lore.kernel.org/all/20200702143045.23429-1-andriy.shevchenko@linux.intel.com/ Reported-by: Mick Lorain <micklorain@protonmail.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-04-08 14:40:23 +02:00
