* Revert "config: Add toggle for bootdevice information"Gerd Hoffmann2019-11-181-7/+0
| | | | This reverts commit cb56f61c109985ad71078b1fb2e65bd4d6ed1a59.
* config: Add toggle for bootdevice informationSam Eiderman2019-11-061-0/+7
| | | | | | | | | | | | | | | Add the "BOOTDEVICES" toggle to remove boot device information received through fw_cfg. We will use this toggle in QEMU to reduce the size of the 128k SeaBIOS rom, which is only used in old compat versions, where this boot device information does not exist.

* add serial console supportGerd Hoffmann2017-09-221-0/+5
| | | | | | | | | 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>
* NVMe: Allow NVMe to be enabled on real hardwareKevin O'Connor2017-05-101-1/+1
| | | | | | | A couple of users have reported success with the NVMe driver on real hardware, so allow it to be enabled outside of QEMU. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* block: add NVMe boot supportJulian Stecklina2017-02-201-0/+6
| | | | | | | | | | | | 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>

* Add minimal support for machines without hardware interruptsKevin O'Connor2015-08-241-1/+12
| | | | | | | | | | Some Chromebooks (with Baytrail CPUs) apparently do not support routing of legacy interrupts. This patch adds minimal support for running SeaBIOS in such an environment. Even with this patch, it is known that old operating systems and even some recent bootloaders will not function without real hardware interrupts. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | Don't require coreboot to use CONFIG_FLASH_FLOPPY - with the latest QEMU, it's possible to place a floppy image into fw_cfg using the qemu command line (eg, "-fw_cfg name=floppyimg/MyFloppy,file=file.img"). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* timer: Add CONFIG_TSC_TIMER build option to disable the CPU TSC timerKevin O'Connor2015-07-231-2/+8
| | | | | | | | | | Allow users to remove the CPU timestamp counter support at compile time. The PMTIMER is frequently used instead of the TSC and this compile time option allows one to strip a few bytes from the final binary. This change also defaults the internal timer to use the PIT based timer until the PMTIMER or TSC is detected. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Add multiboot support.Vladimir Serbinenko2015-06-011-0/+7
| | | | | | | | | | | | | | | | | | | | 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.

* Implementation of the TCG BIOS extensionsStefan Berger2015-05-211-0/+7
| | | | | | | | | | | | | | | | | | | | 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'Connor2014-12-291-0/+6
| | | | | | | | 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>
* Implement call32 mechanism using SMIs.Kevin O'Connor2014-10-151-0/+4
| | | | | | | | | | | | | Add support for jumping into 32bit mode using a System Management Mode (SMM) handler. When available, this allows SeaBIOS to transition to 32bit mode even when called in vm86 mode. It will also prevent the clobbering of the segment registers. Currently, the SMM mode is only supported in QEMU when running in TCG mode. Also, QEMU v2.1 (or later) is needed for it to work when in vm86 mode. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Replace CONFIG_THREAD_OPTIONROMS with a runtime config setting.Kevin O'Connor2014-04-071-11/+0
| | | | | | | | | | | | | | Replace the CONFIG_THREAD_OPTIONROMS option with the CBFS (or fw_cfg) file "etc/threads". This allows for the "threads during optionrom" capability to be enabled/disabled without requiring SeaBIOS to be recompiled. A value of "2" in this file will enable threads to run during option rom execution. This change also allows for all threads to be disabled via the same runtime config file. Setting the file to a value of "0" will cause SeaBIOS to perform all hardware initialization serially. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* xhci: Allow the XHCI USB controller to be enabled for coreboot.Kevin O'Connor2014-01-291-1/+1
| | | | | | | Initial tests look promising and at least two different real-world chipsets show limited functionality with the support enabled. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* coreboot: Support alternative locations for CBFS.Kevin O'Connor2014-01-221-1/+11
| | | | | | | | | The Google builds of SeaBIOS place the CBFS data in a non-standard location. Add a config parameter to support non-standard locations. This is based on a patch from Stefan Reinauer <reinauer@chromium.org> in the Chromium seabios repo (commit 60534ec785). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | | | | | | | | | | | Load files through romfile loader and use for acpi tables. We need the RSDP pointer to hang the rest of the tables off it, to detect that we simply scan all memory in FSEG. Add an option to disable this feature (useful for old QEMU versions).

| | | | | | | | | | | | | | Testing was done on windows images (win 2008/2012) taken from esx with vmware tools installed and boot disk configured to use pvscsi. Also I've used linux (ubuntu 12.04) where pvscsi drivers are installed by default and booted it using qemu cmd similar to this: ./x86_64-softmmu/qemu-system-x86_64 -snapshot -device pvscsi,id=pvscsi0 \ -device scsi-disk,bus=pvscsi0.0,drive=drive0 \ -drive id=drive0,if=none,file=ubuntu-12.04.qcow2 \ -bios roms/seabios/out/bios.bin Signed-off-by: Evgeny Budilovsky <evgeny.budilovsky@ravellosystems.com>

* usb: add xhci supportGerd Hoffmann2013-09-191-0/+6
| | | | | | | | | | | | $subject says all. Support for usb3 streams is not implemented yet, otherwise it is fully functional. Tested all usb devices supported by qemu (keyboard, storage, usb hubs), except for usb attached scsi in usb3 mode (which needs streams). Tested on qemu only, tagged with QEMU_HARDWARE because of that. Testing with physical hardware to be done. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
* Add config option to support memory allocations in 9-segment.Kevin O'Connor2013-08-101-0/+9
| | | | | | | | | | | Internal "low memory" allocations are currently placed in the UMB region (0xc0000-0xf0000). However, there have been reports of some real machines that do not support DMA to this area of memory. So, add a compile time config option (off by default) to support placing all internal low-memory allocations at the end of the 640K real-memory area (0x90000-0xa0000). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Default unused UMB areas to be read-only.Kevin O'Connor2013-07-211-0/+12
| | | | | | | | | | | | It looks like MSDOS 6 wants the UMB area to be read-only in order for it to use it. FreeDOS doesn't care, but it always maps a page from high mem when it does use the area. So, add an option to control whether unused UMB ram is marked read-only and default it to read-only as that seems to be more compatible. This also fixes an off-by-one bug in the shadow range checking code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* acpi: make default DSDT optionalMichael S. Tsirkin2013-03-221-0/+10
| | | | | | | | | | | | | | Since commit f7e4dd6c18ccfbaf6cd2f5eaaed2b77cabc8a406 QEMU loads its own copy of DSDT, so let's not build in PIIX. This makes building in the DSDT an option, default to on (built-in). If no one complains for a while, we'll be able to switch it off and then maybe remove altogether.

* Support using the "extra stack" for all 16bit irq entry points.Kevin O'Connor2013-03-031-0/+9
| | | | | | | | | | | Using the internal stack reduces the amount of space that SeaBIOS uses on the caller's stack. This is known to help some very old operating systems (like DOS 1.0). However, there is a possibility that this will break any operating systems that calls a legacy 16bit irq in 16bit protected mode (no OSes have yet to be identified as doing this), so make the ability config dependent.

* Consistently use CONFIG_COREBOOT, CONFIG_QEMU, and runningOnXen().Kevin O'Connor2013-02-121-4/+4
| | | | | | | | | | | | | | | | | | | | | CONFIG_QEMU means compile to start from QEMU (and possibly Xen/KVM/Bochs) and definitely running under QEMU (or Xen/KVM/Bochs). CONFIG_COREBOOT means compile for coreboot and definitely running under coreboot. Places that used CONFIG_COREBOOT to mean "running on real hardware" have been changed to use !CONFIG_QEMU. CONFIG_QEMU_HARDWARE enables support for some virtual hardware devices even if QEMU didn't start SeaBIOS. usingXen() is replaced by runningOnXen(). runningOnQEMU() is added to hardware devices that are only safe to access when we are sure we are running under QEMU (or Xen/KVM/Bochs). Neither the coreboot nor the csm code currently enable runningOnQEMU, but future patches may. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* add acpi pmtimer supportGerd Hoffmann2012-09-101-0/+6
| | | | | | | | | | | | This patch makes seabios use the acpi pmtimer instead of tsc for timekeeping.

* lsi53c895a boot supportGerd Hoffmann2012-07-211-0/+6
| | | | | | | | | | | | | This patch adds support for the lsi53c895a scsi host adapter, allowing seabios to boot from scsi disks and cdroms connected to the lsi scsi hba emulated by qemu. This driver was written by looking at the expectations of qemu's lsi emulation. I have no idea idea how close this is to work on real hardware, and I somehow doubt anyone cares given the age of physical lsi scsi cards. It depends on !COREBOOT for that reason.

* usb attached scsi boot supportGerd Hoffmann2012-07-211-1/+7
| | | | | | | | | | | | | | | | This patch adds support for booting from UAS (usb attached scsi) devices. For now only usb 2.0 support is there. On usb 3.0 the UAS protocol uses streams, so changes will be required to make usb 3.0 devices fly once we have a xhci host controller driver. So far the driver has been tested on qemu-emulated virtual hardware only. In theory should just work on bare metal too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* Remove SMBIOS generation on coreboot hack.Kevin O'Connor2012-06-091-3/+1
| | | | | | | | | | Early versions of coreboot did not create an SMBIOS table (which Linux needs in order to use the ACPI tables), so SeaBIOS had a hack to generate an SMBIOS table. However, recent versions of coreboot can generate an SMBIOS table, so there is no longer a reason to support this hack. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
