[PATCH v2] Update EFI_COMPATIBILITY16_TABLE to match 0.98 spec update
by David Woodhouse June 2, 2014

June 2, 2014

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 May 30, 2014

May 30, 2014

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 May 28, 2014

May 28, 2014

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] pci: improve io address space allocation
by Gerd Hoffmann Feb. 2, 2014

Feb. 2, 2014

This patch improves the io address space allocation. It adds a check that the region above 0xc000 which is traditionally used for pci io is actually big enougth. If it isn't it tries the larger window at 0x1000. If that is to small too it errors out. When creating guests with multiple pci-pci bridges (and devices with io regions behind them) the 0xc000 -> 0xffff region quickly becomes too small. While being at it document the io address space layout used by qemu/seabios.

[RFC][PATCH] coreboot: Add support for a "links" file to have aliases in CBFS.
by Kevin O'Connor Jan. 30, 2014

Jan. 30, 2014

The "links" file is a newline separated list where each line is a "link name" followed by a "destination name" separated by a space character. For each line, SeaBIOS will consider each "link name" to be a CBFS file that has the contents found in the CBFS file with "destination name". Signed-off-by: Kevin O'Connor <kevin(a)koconnor.net> --- This patch may be useful for those using intel option roms where the same rom is used on a number of VGA devices with different vendor/device ids. With this patch, one can make a "links" file with the list of devices (eg, "pci8086,0a06.rom") that all point to the same physical rom (eg, "pci8086,0406.rom"). It's possible to implement this aliasing approach in a number of different ways. The approach taken in this patch is a single file with all the link names. This was done based on feedback that there could be 20 or more aliases for a single rom and creating individual CBFS files for each link would be unwieldy. That said, I'm not sure this is the best approach. I'm circulating it for comments. --- src/fw/coreboot.c | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) diff --git a/src/fw/coreboot.c b/src/fw/coreboot.c index df8fca8..270d01a 100644 --- a/src/fw/coreboot.c +++ b/src/fw/coreboot.c @@ -408,6 +408,40 @@ coreboot_cbfs_init(void) fhdr = (void*)ALIGN((u32)cfile->data + cfile->rawsize , be32_to_cpu(hdr->align)); } + + // Process CBFS links file.

The Intel VGA stuff seems to be pretty stable and it's only a few fields that need to be passed back. What about placing the required info in a coreboot table - then SeaBIOS can just pass back the desired fields and not have to have board by board specific logic. BTW, I didn't port over "Alex" as it seems to be totally different from the other boards. -Kevin
