2016-07-01fw/msr_feature_control: add support to set MSR_IA32_FEATURE_CONTROLrel-1.9.3Haozhong Zhang2-11/+21
OS usually expects BIOS to set certain bits in MSR_IA32_FEATURE_CONTROL for some features (e.g. VMX and LMCE). QEMU provides a fw_cfg file "etc/msr_feature_control" to advise bits that should be set in MSR_IA32_FEATURE_CONTROL. If this file exists, SeaBIOS will set the advised bits in that MSR.

2016-06-01fw/pci: Add support for mapping Intel IGD via QEMUAlex Williamson1-0/+48
QEMU provides two fw_cfg files to support IGD. The first holds the OpRegion data which holds the Video BIOS Table (VBT). This needs to be copied into reserved memory and the address stored in the ASL Storage register of the device at 0xFC offset in PCI config space. The OpRegion is generally 8KB. This file is named "etc/igd-opregion". The second file tells us the required size of the stolen memory space for the device. This space requires 1MB alignment and is generally either 1MB to 8MB depending on hardware config, but may be hundreds of MB for user specified stolen memory. The base address of the reserved memory allocated for this is written back to the Base Data of Stolen Memory register (BDSM) at PCI config offset 0x5C on the device. This file is named "etc/igd-bdsm-size". QEMU documents these fw_cfg entries in docs/igd-assign.txt.

2016-02-24build: fix .text section address alignmentKevin O'Connor1-4/+10

2016-01-15fw/pci: do not automatically allocate IO region for PCIe bridgesMarcel Apfelbaum1-4/+5
PCIe downstream ports (Root Ports and switches Downstream Ports) appear to firmware as PCI-PCI bridges and a 4K IO space is allocated for them even if there is no device behind them requesting IO space, all that for hotplug purpose. However, PCIe devices can work without IO, so there is no need to allocate IO space for hotplug. Acked-by: Michael S.

2016-01-15coreboot: Check for unaligned cbfs headerKevin O'Connor1-0/+4
If the CBFS header is invalid and points to 0xffffffff it could cause SeaBIOS to read past the 4GB boundary and cause an exception.

2016-01-15scsi: Do not call printf() from scsi_is_ready()Kevin O'Connor1-1/+1
The scsi_is_ready() function may be called from a thread, and it is not valid to call printf() from a thread. Convert printf() to dprintf() to avoid this possibility. This does mean that cdrom detection (from cdrom_boot() ) may not give notification of slow cdrom drives to a user. However, the extra medium detection time is unlikely to be large anyway.

2016-01-15xhci: Wait for port enable even for USB3 devicesKevin O'Connor1-22/+21
Some USB3 controllers (and/or devices) need additional time after the device is detected to place the port in an enabled state. Wait for the controller to report enabled before proceeding.

2015-10-23build: Allow official tarball builds to be considered "clean"Kevin O'Connor1-2/+8
If building from an official tarball and EXTRAVERSION info is provided, then consider the build to be "clean" (don't include hostname/build timestamp). This is done on the expectation that EXTRAVERSION will have enough information to allow developers to find the builder and build environment should a defect be reported, and therefore the hostname/timestamp is not necessary.

2015-10-15stacks: Use macro wrappers for call32() and stack_hop_back()Kevin O'Connor8-44/+41
The C code only uses _cfuncX_ prefixes for parameters to the call32(), stack_hop_back(), and call32_params() functions. It's simpler to use macro wrappers around those functions which provide the required prefix. This also changes the parameter order of stack_hop() and stack_hop_back() to use the more natural (func, params) ordering. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2015-10-15build: Generate "reproducible" version strings on "clean" buildsKevin O'Connor1-4/+6
