This patch series includes several patches that I made in the process, some are very loosely related. The driver developed by Connor supports console via USB3 debug capability. The capability is designed to operate mostly independently of normal XHCI driver, so this patch series allows dom0 to drive standard USB3 controller part, while Xen uses DbC for console output. Changes since RFC: - move the driver to xue.c, remove non-Xen parts, remove now unneeded abstraction - adjust for Xen code style - build for x86 only - drop patch hidding the device from dom0 Changes since v1: - drop ehci patch - already applied - adjust for review comments from Jan (see changelogs in individual patches) Changes since v2: - add runtime option to share (or not) the controller with dom0 or other domains - add RX support - several smaller changes according to review comments Cc: Andrew Cooper Cc: George Dunlap Cc: Jan Beulich Cc: Julien Grall Cc: Stefano Stabellini Cc: Wei Liu Cc: "Roger Pau Monné" Cc: Paul Durrant Cc: Kevin Tian Cc: Connor Davis Connor Davis (1): drivers/char: Add support for USB3 DbC debugger Marek Marczykowski-Górecki (9): drivers/char: reset XHCI ports when initializing dbc drivers/char: add support for selecting specific xhci console: support multiple serial console simultaneously IOMMU: add common API for device reserved memory IOMMU/VT-d: wire common device reserved memory API IOMMU/AMD: wire common device reserved memory API drivers/char: mark DMA buffers as reserved for the XHCI drivers/char: allow driving the rest of XHCI by a domain while Xen uses DbC driver/char: add RX support to the XHCI driver docs/misc/xen-command-line.pandoc | 19 +- xen/arch/x86/include/asm/fixmap.h | 4 +- xen/arch/x86/setup.c | 1 +- xen/drivers/char/Kconfig | 20 +- xen/drivers/char/Makefile | 1 +- xen/drivers/char/console.c | 97 +- xen/drivers/char/xhci-dbc.c | 1367 +++++++++++++++++++++++- xen/drivers/passthrough/amd/iommu_acpi.c | 21 +- xen/drivers/passthrough/iommu.c | 45 +- xen/drivers/passthrough/vtd/dmar.c | 201 +-- xen/include/xen/iommu.h | 13 +- xen/include/xen/serial.h | 6 +- 12 files changed, 1690 insertions(+), 105 deletions(-) create mode 100644 xen/drivers/char/xhci-dbc.c base-commit: 4df2e99d731402da48afb19dc970ccab5a0814d6 -- git-series 0.9.1
