Change in coreboot[master]: lp/drivers/usb: Add quirk for QEMU XHCI root hub
by Duncan Laurie (Code Review) 01 May '20

01 May '20

Duncan Laurie has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/39839 ) Change subject: lp/drivers/usb: Add quirk for QEMU XHCI root hub ...................................................................... lp/drivers/usb: Add quirk for QEMU XHCI root hub The QEMU XHCI driver does not implement the Port Change Detect bit in the USBSTS register. As a result no devices are attached without looking at each port individually. Detect this as a quirk based on the QEMU XHCI controller PCI ID, and apply it to the root hub quirk list so it can get used by the generic hub driver to skip this check. With this change an attached USB mass storage device is detected and able to boot when supplied to qemu: -drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img -device qemu-xhci,id-xhci -device usb-storage,bus=xhci.0,drive=usbmsc Change-Id: I6689cb1dbb24c93d45f5c5ef040b713925d07588 Signed-off-by: Duncan Laurie <dlaurie(a)google.com> --- M payloads/libpayload/drivers/usb/generic_hub.c M payloads/libpayload/drivers/usb/quirks.c M payloads/libpayload/drivers/usb/xhci.c M payloads/libpayload/include/usb/usb.h 4 files changed, 35 insertions(+), 2 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/39/39839/1 diff --git a/payloads/libpayload/drivers/usb/generic_hub.c b/payloads/libpayload/drivers/usb/generic_hub.c index 9d444ee..7263400 100644 --- a/payloads/libpayload/drivers/usb/generic_hub.c +++ b/payloads/libpayload/drivers/usb/generic_hub.c @@ -218,9 +218,11 @@ if (!hub) return; - if (hub->ops->hub_status_changed && - hub->ops->hub_status_changed(dev) != 1) + if (!(dev->quirks & USB_QUIRK_HUB_NO_USBSTS_PCD) && + hub->ops->hub_status_changed && + hub->ops->hub_status_changed(dev) != 1) { return; + } int port; for (port = 1; port <= hub->num_ports; ++port) { diff --git a/payloads/libpayload/drivers/usb/quirks.c b/payloads/libpayload/drivers/usb/quirks.c index 0a35149..556ce9e 100644 --- a/payloads/libpayload/drivers/usb/quirks.c +++ b/payloads/libpayload/drivers/usb/quirks.c @@ -59,6 +59,31 @@ */ }; +#if CONFIG(LP_USB_PCI) +usb_quirks_t pci_quirks[] = { + /* QEMU XHCI root hub does not implement port change detect */ + { 0x1b36, 0x000d, USB_QUIRK_HUB_NO_USBSTS_PCD, 0 }, +}; + +u32 pci_quirk_check(pcidev_t controller) +{ + int i; + u16 vendor = pci_read_config16(controller, REG_VENDOR_ID); + u16 device = pci_read_config16(controller, REG_DEVICE_ID); + + for (i = 0; i < ARRAY_SIZE(pci_quirks); i++) { + if ((pci_quirks[i].vendor == vendor) && + (pci_quirks[i].device == device)) { + printf("PCI quirks enabled: %08x\n", + pci_quirks[i].quirks); + return pci_quirks[i].quirks; + } + } + + return USB_QUIRK_NONE; +} +#endif + u32 usb_quirk_check(u16 vendor, u16 device) { int i; diff --git a/payloads/libpayload/drivers/usb/xhci.c b/payloads/libpayload/drivers/usb/xhci.c index 659861f..55ca89f 100644 --- a/payloads/libpayload/drivers/usb/xhci.c +++ b/payloads/libpayload/drivers/usb/xhci.c @@ -316,9 +316,13 @@ controller = xhci_init((unsigned long)reg_addr); if (controller) { + xhci_t *xhci = controller->instance; controller->pcidev = addr; xhci_switch_ppt_ports(addr); + + /* Set up any quirks for controller root hub */ + xhci->roothub->quirks = pci_quirk_check(addr); } return controller; diff --git a/payloads/libpayload/include/usb/usb.h b/payloads/libpayload/include/usb/usb.h index 5d27f7c..328e883 100644 --- a/payloads/libpayload/include/usb/usb.h +++ b/payloads/libpayload/include/usb/usb.h @@ -318,6 +318,7 @@ int usb_attach_device(hci_t *controller, int hubaddress, int port, usb_speed speed); +u32 pci_quirk_check(pcidev_t controller); u32 usb_quirk_check(u16 vendor, u16 device); int usb_interface_check(u16 vendor, u16 device); @@ -330,6 +331,7 @@ #define USB_QUIRK_MSC_FORCE_TRANS_CBI_I (1 << 6) #define USB_QUIRK_MSC_NO_TEST_UNIT_READY (1 << 7) #define USB_QUIRK_MSC_SHORT_INQUIRY (1 << 8) +#define USB_QUIRK_HUB_NO_USBSTS_PCD (1 << 9) #define USB_QUIRK_TEST (1 << 31) #define USB_QUIRK_NONE 0 -- To view, visit https://review.coreboot.org/c/coreboot/+/39839 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I6689cb1dbb24c93d45f5c5ef040b713925d07588 Gerrit-Change-Number: 39839 Gerrit-PatchSet: 1 Gerrit-Owner: Duncan Laurie <dlaurie(a)chromium.org> Gerrit-MessageType: newchange

Change in coreboot[master]: mb/ocp/tiogapass: Update UPD IIO bifurcation at run-time

For detail please reference Facebook Server Intel Motherboard v4.0, Sec. 10.1.2 Riser card types. With the engineering build FSP, it can only configure IIO for one socket so my local test needs to remove all socket1 elements from tp_iio_bifur_table.

Change in coreboot[master]: mb/tiogapass: exclude the consequences of reconfig GPIO in FSP-M
by Maxim Polyakov (Code Review) 01 May '20

Maxim Polyakov has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/40730 ) Change subject: mb/tiogapass: exclude the consequences of reconfig GPIO in FSP-M ...................................................................... mb/tiogapass: exclude the consequences of reconfig GPIO in FSP-M FSP-M can reconfigure the GPIO controller inside Lewisburg PCH. Since FSP-M is provided as a binary file, we will not be able to change the contents inside of this file. We should be sure that after romstage the pads will be configured according to the configuration from gpio.h only. This patch reconfigures the GPIO to ramstage.
