[PATCH 1/3] debug: Add runtime option to not report the debug serial port to the OS.
by Kevin O'Connor 20 Jan '14

20 Jan '14

DOS resets the serial ports reported by the BIOS. This can mess up debugging and timing when the serial baud rate changes on the debug port. The new "etc/advertise-serial-debug-port" option allows one to suppress the debug serial port from the normal list of serial ports the BIOS reports to DOS.

[PATCH] build: Update kconfig to version in Linux 3.13.
by Kevin O'Connor 20 Jan '14

20 Jan '14

Update kconfig (from Linux v3.11-rc6) to the latest version (Linux v3.13). This copyies kconfig from Linux with only the changes necessary to work with the SeaBIOS build (the equivalent of the earlier SeaBIOS 0da7bfdf commit) and the changes necessary to always emit symbols (SeaBIOS b623e7c5 commit).

[PATCH] init_virtio_scsi(): reset the HBA before freeing its virtio ring
by Laszlo Ersek 17 Jan '14

17 Jan '14

When init_virtio_scsi() finds no SCSI targets connected to the HBA, it frees the virtio ring. Other code in SeaBIOS proceeds to overwrite the area. However, the ring is in use by qemu at that point -- not only did we report the (ACK|DRIVER|DRIVER_OK) status earlier, we even communicated over the ring. Of course SeaBIOS doesn't "kick" the HBA ever again, hence qemu has no reason to look at the ring. However, when qemu uses KVM acceleration, and ioeventfd is enabled for the HBA, then a vmstate change to "running" (including stop->cont monitor commands and incoming migration) "forces" a kick (see qemu commit 25db9ebe). Qemu then tries to interpret whatever unrelated guest data is in the HBA's original ring area, as virtio protocol. Qemu exits upon seeing the garbage. init_virtio_scsi() should reset the HBA before allowing the virtio ring memory to be reused. Device reset causes the hypervisor to drop its references. This change is justified / underpinned by pure virtio-spec compliance as well.

[PATCH] seabios: restore piix pm config registers after resume
by Marcel Apfelbaum 15 Jan '14

15 Jan '14

On resume, the OS queries the power management event that caused it. In order to complete this task, it executes some reads to the piix pm io space. This all happens before the OS has a chance to restore the PCI config space for devices, so it is bios's responsibility to make sure the pm IO space is configured correctly. (During suspend, the piix pm configuration space is lost). Note: For 'ordinary' pci devices the config space is saved by the OS on sleep and restored on resume. Signed-off-by: Marcel Apfelbaum <marcel.a(a)redhat.com> --- This patch is based on Michael S. Tsirkin's patch: [SeaBIOS] [PATCH] seabios: call pci_init_device on resume If Michael agrees with it, I'll add him to signed-off section. Notes: - Without this patch the OS gets stuck because it tries repeatedly to read/write to pm io space, but the memory region is not enabled, so -1 is returned. - After resume the OS does not actually use the pm base address configured by the bios to get the IO ports, but uses the value from the ACPI FADT table actually. However, as a side effect of the configuration, the pm-io space is enabled by Qemu and the OS can continue the the boot sequence. - Bioses used for hardware like coreboot have the same init sequence for piix, see enable_pm from src/southbridge/intel/i82371eb/early_pm.c. src/fw/pciinit.c | 22 ++++++++++++++++++++-- src/hw/pci.c | 31 ++++++++++++++++++++----------- src/hw/pci.h | 1 + src/resume.c | 8 ++++++++ src/util.h | 1 + 5 files changed, 50 insertions(+), 13 deletions(-) diff --git a/src/fw/pciinit.c b/src/fw/pciinit.c index a24b8ff..252328f 100644 --- a/src/fw/pciinit.c +++ b/src/fw/pciinit.c @@ -230,8 +230,7 @@ static void apple_macio_setup(struct pci_device *pci, void *arg) pci_set_io_region_addr(pci, 0, 0x80800000, 0);
