2020-05-15virtio-mmio: device probing and initialization.Gerd Hoffmann1-1/+1
Add virtio_mmio_setup_one() to setup virtio mmio devices. Add vp_init_mmio() to initialize device struct. Because virtio-pci and virtio-mmio are quite simliar we reuse the infrastructure we already have for virtio-pci and just setup struct vp_cap for virtio-mmio.

2020-05-14build: use -fcf-protection=none when availableChristian Ehrhardt1-0/+1
Some hardened gcc v9 compilers (such as the one in Ubuntu) default this option which for seabios leads to emulation errors when running in KVM (does not trigger in TCG) on older intel chips of the Penryn generation (~2006-2008). The symptom appears as endbr32/endbr64 interpretation failures and in KVM it looks like: KVM internal error.

2019-08-23Makefile: Build with -Wno-address-of-packed-memberKevin O'Connor1-0/+1
Building with gcc v9 causes lots of warnings about pointers to packed variables. However, SeaBIOS is limited to x86 where unaligned reads/writes are supported by the cpu. So, disable that warning. Signed-off-by: Kevin O'Connor <kevin@koconnor.net> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com>
2019-03-15vga: add atiext driverGerd Hoffmann1-1/+1
Supports qemu emulated ati cards. They have been added in qemu 4.0. Acceleration support (in qemu) is pretty rough still. A simple framebuffer works fine though. Available models: * ati rage 128 pro * ati rv100 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2019-03-14vga: move modelist from bochsvga.c to new svgamodes.cGerd Hoffmann1-1/+1
So other drivers can simply use the same list too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2018-06-22qemu: add qemu ramfb supportGerd Hoffmann1-1/+1
Add support for qemu ramfb. This is a simple boot framebuffer device, with normal ram being used to back the framebuffer and fw_cfg being used to configure the device. Use case (on x86): boot display for vgpu devices (which neither emulate vga nor have a vgabios). Sharing fw_cfg code with seabios turned out to be difficuilt due to various dependencies the code has on infrastructure which only seabios has. So include a copy of the code here, with those dependencies removed and also stripped down because we don't need a non-dma fallback here. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2018-06-22qemu: add bochs-display supportGerd Hoffmann1-1/+1
Use coreboot text mode emulation to also support the qemu bochs-display device. This is a new display device supporting simple linear framebuffers, using the bochs register interface. No support for legacy vga (text modes, planar modes, cga modes, 8bpp palette modes all dropped). The bochs interface is compatible with the qemu stdvga.

2017-09-22add serial console supportGerd Hoffmann1-2/+2
Redirect int10 calls to serial console output. Parse serial input and queue key events. The serial console can work both as primary display and in parallel to another vga display (splitmode). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2017-02-20block: add NVMe boot supportJulian Stecklina1-1/+1
This patch enables SeaBIOS to boot from NVMe. Finding namespaces and basic I/O works. Testing has been done in qemu and so far it works with Grub, syslinux, and the FreeBSD loader. You need a recent Qemu (>= 2.7.0), because older versions have buggy NVMe support. The NVMe code is currently only enabled on Qemu due to lack of testing on real hardware.

2016-02-03pci: Split low-level pci code from higher-level 'struct pci_device' codeKevin O'Connor1-1/+1
Split pci.c into pci.c and pcidevice.c. The low-level code that interacts directly with the PCI devices remains in pci.c, while functions dealing with the higher level pci_device cache move to pcidevice.c. Only pci.c is needed in 16bit mode. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2015-11-19acpi: Don't build SSDT files on every build; store them in gitKevin O'Connor1-2/+2
The SSDT files are rarely modified - recent QEMU versions don't use them at all and adding features to them in SeaBIOS has been deprecated. It no longer makes sense to generate them on every build. The content will remain (for use on old machine types in QEMU) in static files committed to the SeaBIOS git repo. If the contents do need to be generated a new build target (make iasl) is available.

Replace it with ability to add extra version information at build time via "make EXTRAVERSION=xyz". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2015-10-15e820: Rename memmap.c to e820map.c and use consistent "e820_" prefixKevin O'Connor1-1/+1
Rename memmap.c to e820map.c as the code in that file only deals with maintaining the e820 map. Move all the e820 definitions to new file e820map.h and use a consistent "e820_" prefix on all exported functions. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

2015-07-01virtio: run drivers in 32bit modeGerd Hoffmann1-1/+1
virtio version 1.0 registers can (and actually do in the qemu implementation) live in mmio space. So we must run the blk and scsi virtio drivers in 32bit mode, otherwise we can't access them. This also allows to drop a bunch of GET_LOWFLAT calls from the virtio code in the following patches. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-06-03build: Support "make VERSION=xyz" to override the default build versionKevin O'Connor1-2/+2
Add a build option to explicitly set the version information compiled into the seabios and seavgabios binaries. This may assist in reproducible builds or to better link builds to distribution packages. If the new "VERSION=" parameter is not provided then the default build version remains unchanged. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2015-06-01Add multiboot support.Vladimir Serbinenko1-1/+1
I've been successfully using SeaBIOS as secondary bootloader. In more details I have GRUB2-as-payload in flash together with coreboot. SeaBIOS binary is on the HDD and loaded by GRUB when needed. This has an unfortunate consequence that I have to keep vga oprom in flash even if usually I boot without it. This patches makes bios.bin.elf multiboot executable with files passed as modules. Example: menuentry "SeaBIOS (mb)" --unrestricted { root=ahci0,2 multiboot /bios.bin.elf module /vgabios_x230.rom name=pci8086,0166.rom } the parameter name= specifies under which name SeaBIOS will see it.

2015-05-21Support for BIOS interrupt handlerStefan Berger1-1/+1
This patch implements the TCG BIOS interrupt handler 1ah. It is for example used by trusted grub. This patch adds an implementation of SHA1 (following NIST specs., IETF RFC 3147 and Wikipedia) for speeding up measurements of code. Trusted Grub for example makes use of this interface and measures (calculates SHA1) of the Linux kernel and initrd. Those files can be rather large and hunting their bytes through the TIS interface as part of the int handler commands invoked by trusted grub does take quite some time due to the many vmexits the interface is creating (one per byte). There is also a threshold for the size of data to hash (100k) below which the TPM is used and above the internal faster SHA1 algorithm is used. This patch for example enables trusted grub to interact with the TPM and take additional measurements.

2015-05-21Implementation of the TCG BIOS extensionsStefan Berger1-2/+3
This patch implements the main part of the TCG BIOS extensions. It provides the following functionality: - initialization of the TCPA ACPI table used for logging of measurements - initialization of the TPM by sending a sequence of commands to it - proper setup of the TPM before the BIOS hands over control to the bootloader - support for S3 resume; BIOS sends TPM_Startup(ST_STATE) to TPM - enable configuration of SeaBIOS to be built with TCGBIOS extensions All TCG BIOS extensions are activated with CONFIG_TCGBIOS. Structures that are needed in subsequent patches are also included in tcgbios.h at this point. The effect of this patch is that it initialized the TPM upon VM start and S3 resume.

2014-12-29sdcard: Initial support for SD cards on PCI SDHCI controllers on QEMUKevin O'Connor1-1/+1
This adds basic read/write support for SD cards emulated by QEMU. This code is not expected to work on real hardware, because the current controller and card initialization is not robust. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

2014-06-05build: use -m16 where available instead of asm(".code16gcc")David Woodhouse1-1/+3
GCC 4.9 and clang 3.5 support the -m16 option on the command line which supersedes the hackish ".code16gcc" assembler directive. Use it where possible. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2014-06-05build: Avoid absolute paths during "whole-program" compiling.Kevin O'Connor1-2/+2
The build currently does a textual include of all files in order to use the -fwhole-compile optimization. Update it to use relative file paths instead of absolute file paths. This makes the section names in the resulting binary more readable. It also makes the build easier on some Windows hosts. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
