This patchset implements XHCI on sbsa-ref board to replace EHCI. As sbsa-ref does not have DRAM below 4G, it cannot utilize EHCI that only has 32-bit DMA capablity. Now this board has XHCI as an available usb controller with 64-bit DMA capablity.
History: v2 -> v3: - remained the original USB hierarchy in DSDT - changed two usb ports from type A to type C - refactored patchset v1 -> v2: - rebased on master as v1 did not applied - moved pcd setting in dec file into the first commit Yuquan Wang (1): Platform/SbsaQemu: add XHCI support and replace EHCI Silicon/Qemu/SbsaQemu/SbsaQemu.dec | 4 +- Platform/Qemu/SbsaQemu/SbsaQemu.dsc | 6 +-- .../Qemu/SbsaQemu/AcpiTables/AcpiTables.inf | 4 +- .../SbsaQemuPlatformDxe.inf | 2 + .../SbsaQemuPlatformDxe/SbsaQemuPlatformDxe.c | 41 +++++++++++++++---- Silicon/Qemu/SbsaQemu/AcpiTables/Dsdt.asl | 15 +++---- 6 files changed, 49 insertions(+), 23 deletions(-) -- 2.34.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
