Add patch 1 to combine two if statements for Etron xHCI host in xhci_pci_quirks(): xhci: Combine two if statements for Etron xHCI host Add patch 5 to prevent the xHCI driver from printing a "Transfer event TRB DMA ptr not part of current TD" error message when an error is detected while processing an one-TRB isoc TD: xhci: Correct handling of one-TRB isoc TD on Etron xHCI host In fact, these problems are unlikely to occur on other host controllers, so adding XHCI_ETRON_HOST quirk flag to invoke these workarounds: xhci: Don't issue Reset Device command to Etron xHCI host xhci: Fix control transfer error on Etron xHCI host xhci: Correct handling of one-TRB isoc TD on Etron xHCI host Apply XHCI_NO_SOFT_RETRY quirk flag to disable Soft Retry: xhci: Don't perform Soft Retry for Etron xHCI host --- Changes in v2: - Modify commit message - Remove XHCI_NO_RESET_DEVICE/XHCI_NO_BREAK_CTRL_TD quirk flag - Add XHCI_ETRON_HOST quirk flag, thanks for the suggestion by Michal - Check device speed before invoking the workaround - Add (xhci: Combine two if statements for Etron xHCI host) - Add (xhci: Correct handling of one-TRB isoc TD on Etron xHCI host) - Link to v1: https://lore.kernel.org/all/20240911051716.6572-4-ki.chiang65@xxxxxxxxx Kuangyi Chiang (5): xhci: Combine two if statements for Etron xHCI host xhci: Don't issue Reset Device command to Etron xHCI host xhci: Fix control transfer error on Etron xHCI host xhci: Don't perform Soft Retry for Etron xHCI host xhci: Correct handling of one-TRB isoc TD on Etron xHCI host drivers/usb/host/xhci-pci.c | 10 ++++----- drivers/usb/host/xhci-ring.c | 40 ++++++++++++++++++++++++++---------- drivers/usb/host/xhci.c | 19 +++++++++++++++++ drivers/usb/host/xhci.h | 3 ++- 4 files changed, 54 insertions(+), 18 deletions(-) -- 2.25.1
