[PATCH v2] Update EFI_COMPATIBILITY16_TABLE to match 0.98 spec update
by David Woodhouse 02 Jun '14

02 Jun '14

We expect to use the space between the top of option ROMs and the bottom of our own BIOS code as a stack. OVMF was previously marking the whole region from 0xC0000 to 0xFFFFF read-only before invoking our Legacy16Boot method. Read-only stack considered harmful. Version 0.98 of the CSM spec adds the UmaAddress and UmaSize fields, which allow the CSM to specify a memory region that needs to be writable. There exists CONFIG_MALLOC_UPPERMEMORY which we could turn off to use the 9-segment, but that isn't particularly useful for the CSM case either because that memory isn't ours to play with until the final Legacy16Boot call. There's a LowPmmMemory given to use by UEFI to play with, but that's right in the *middle* of low memory and using that for persistent allocations would be painful. So just require CONFIG_MALLOC_UPPERMEMORY when building a CSM. Signed-off-by: David Woodhouse <David.Woodhouse(a)intel.com> --- v2: Require CONFIG_MALLOC_UPPERMEMORY.

[PATCH 0/3] Run pvscsi driver entirely in 32bit mode.
by Kevin O'Connor 30 May '14

30 May '14

As with the recent change to AHCI, if the pvscsi driver needs to jump into 32bit mode to access a register, then it's better to run the pvscsi driver entirely in 32bit mode. Evgeny, can you take a look at this and give it a test? Also, what command line do you use for testing? I tried testing locally by adding: -device pvscsi,id=pvscsi0 -device scsi-disk,bus=pvscsi0.0,drive=drive0 -drive id=drive0,if=none,file=dos-drivec-new to my qemu command line (both qemu v1.6 and qemu v1.7), but it doesn't work for me even before my changes. It hangs in pvscsi_wait_intr_cmpl(). -Kevin Kevin O'Connor (3): pvscsi: Don't store reference to struct pci_device. pvscsi: Always run entirely in 32bit mode. pvscsi: Remove use of LOWFLAT and GLOBALFLAT macros.

[RFC PATCH] Add support for Intel Quark UART.
by David Woodhouse 28 May '14

28 May '14

This provides basic debug output on the Quark system, assuming that *something* (i.e. coreboot or UEFI) has set it up in advance for us. Signed-off-by: David Woodhouse <David.Woodhouse(a)intel.com> --- I looked briefly at making this part of the CONFIG_DEBUG_SERIAL code, and making that generic enough to handle I/O access *or* MMIO access depending on what's present... but in fact that's probably overkill. This isn't really limited to Quark; it would work with any 16550 device wired up as MMIO32. But we can expand it as required, I think. No point in starting off with the same functionality as the 5000-odd lines of the Linux kernel's 8250_pci.c. What do I need to do if called in 32-bit segmented mode?

[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.

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?
