[PATCH 00/10] XHCI patches for real-hardware
by Kevin O'Connor 13 Jan '14

13 Jan '14

The following is my test series for XHCI. I've gotten it to the point that I can boot from a "super speed" USB flash drive. However, high speed flash drives and low speed keyboard/mouse still don't work for me. Hopefully, when Gerd returns he'll have some insight. The most notable part of this series is the work to make the code auto-detect and handle 64 byte contexts (which the xhci controller on my e350m1 requires). The series is also available at: https://github.com/KevinOConnor/seabios/tree/xhci-testing -Kevin Gerd Hoffmann (1): xhci: allocate scratch pad buffers Kevin O'Connor (9): xhci: Use 64bit writes to ERDP register. xhci: Fix incorrect direction setting on status transmissions. xhci: Set the interval parameter on interrupt pipes. xhci: Verify PAGESIZE register before initializing driver. xhci: Allocate and free the xhci inctx structure on each use. xhci: Move set_address code from xhci_control to xhci_alloc_pipe. xhci: Eliminate 'struct xhci_device'. xhci: Support xhci controllers with 64 byte contexts. xhci: Allow the XHCI USB controller to be enabled for coreboot. src/Kconfig | 2 +- src/hw/usb-xhci.c | 342 +++++++++++++++++++++++++++++------------------------- src/hw/usb-xhci.h | 8 -- src/hw/usb.c | 4 +- src/hw/usb.h | 1 + 5 files changed, 186 insertions(+), 171 deletions(-) -- 1.8.3.1

[PATCH] seabios: call pci_init_device on resume
by Michael S. Tsirkin 13 Jan '14

13 Jan '14

PIIX spec says that most its registers are reset on suspend. However, QEMU didn't reset most of them properly. Now that it started doing that, resume is broken. Fix it up by probing system devices on bus 0 and re-initializing them. Signed-off-by: Michael S.

I've pushed this to the xhci-testing branch at: https://github.com/KevinOConnor/seabios/tree/xhci-testing -Kevin Kevin O'Connor (4): Add call32_params() helper function.

Opal SSC (encrypted) hard drives unsupported, despite TPM support?
by GNUtoo＠no-log.org 30 Dec '13

30 Dec '13

The http://www.coreboot.org/Benefits page says under "possible advantages": * TPMs... with no detail. (note that the three dots are literally on the webpage, not my paraphrasing). Support for TPMs /could/ mean support for self-encrypted (Opal) hard drives, but there are other kinds of TPMs (e.g. fingerprint reading) so it's unclear what actually works on coreboot. Someone in #coreboot hinted (without confidence) that only software encryption is possible under coreboot. Is that true?
