* Makefile: Build with -Wno-address-of-packed-memberKevin O'Connor2019-08-231-0/+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>
* vga: add atiext driverGerd Hoffmann2019-03-151-1/+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>
* vga: move modelist from bochsvga.c to new svgamodes.cGerd Hoffmann2019-03-141-1/+1
| | | | | | So other drivers can simply use the same list too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
* qemu: add qemu ramfb supportGerd Hoffmann2018-06-221-1/+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>
* qemu: add bochs-display supportGerd Hoffmann2018-06-221-1/+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.

* add serial console supportGerd Hoffmann2017-09-221-2/+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>

* block: add NVMe boot supportJulian Stecklina2017-02-201-1/+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. Signed-off-by: Julian Stecklina <jsteckli@amazon.de>

* pci: Split low-level pci code from higher-level 'struct pci_device' codeKevin O'Connor2016-02-031-1/+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>
* acpi: Don't build SSDT files on every build; store them in gitKevin O'Connor2015-11-191-2/+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. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | | 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>

* virtio: run drivers in 32bit modeGerd Hoffmann2015-07-011-1/+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.

* build: Support "make VERSION=xyz" to override the default build versionKevin O'Connor2015-06-031-2/+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.

* Add multiboot support.Vladimir Serbinenko2015-06-011-1/+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.

* Support for BIOS interrupt handlerStefan Berger2015-05-211-1/+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.

* Implementation of the TCG BIOS extensionsStefan Berger2015-05-211-2/+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.

* sdcard: Initial support for SD cards on PCI SDHCI controllers on QEMUKevin O'Connor2014-12-291-1/+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>

* build: Avoid absolute paths during "whole-program" compiling.Kevin O'Connor2014-06-051-2/+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.

* build: Don't trash the .config file when src/Kconfig changes.Kevin O'Connor2013-12-231-1/+1
| | | | | | | | | | | | Revision 5325e91e introduced a change to force the rebuild of the .config file when the src/Kconfig (or vgasrc/Kconfig) file changes. However, this was causing a complete rebuild of the user's .config file which would throw away the user's current settings. On a rebuild, use the kbuild olddefconfig rule instead of defconfig to attempt to keep the user's current settings. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* vgabios: Support allocating an extra stack for vgabios calls and default on.Kevin O'Connor2013-12-041-1/+1
| | | | | | | | | | | | | Add code to allocate an extra stack for the main vgabios int 0x10 entry point. The allocation is done via the PMM spec and uses a PCI v3 permanent low memory region request. This request will work with SeaBIOS - it is unknown how many other main BIOS implementations support this PMM call. The extra stack is useful for old DOS programs that call the VGABIOS and expect it to work with very small amounts of stack space. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* Run ahci code entirely in 32bit mode.Kevin O'Connor2013-10-141-2/+2
