* add get_keystroke_full() helperGerd Hoffmann2019-05-171-0/+1
| | | | | | | | | | | | | Switch get_raw_keystroke() to return ax instead of ah, so it returns both scan code and ascii code of the key pressed. Add get_keystroke_full() function which passes up ax to the caller. The get_keystroke() function continues to return the scancode only like it did before. It is a thin wrapper around get_keystroke_full() now though. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
* bootsplash: Added support for 16/24/32bpp in one functionJoseph Pacheco-Corwin2019-02-041-1/+1
| | | | | | | | | | | | | | | | | | | Specifically added support for 16 and 32bpp files, in addition to 24bpp. The function bmp_show() in bmp.c has had the hardcoded check for 24bpp replaced with a general bpp check that uses a % to check for remainder, and returns 1 if the remainder is >0. The previous method for adjusting the BMP data (raw_data_format_adjust_24bpp) relied on a preset 3*bytes_per_line_src, this has been changed and the multiplication is now performed in the function's arguments. This change still allows someone else to reuse the same function for 1/2/4bpp support if necessary. The file util.h has been modified to reflect this decision. The changes to raw_data_format_adjust() is based on an abandoned patch by Gert Menke (submitted March 14, 2017), credit to them for that change and the addition of *bpp to bmp_get_info().

* resume: Don't attempt to use generic reboot mechanisms on QEMUKevin O'Connor2017-03-131-1/+1
| | | | | | | | | | | | | | | | On QEMU it's necessary to manually reset the BIOS memory region between 0xc0000-0x100000 on a reboot. After this manual memory reset is completed, it's not valid to use the generic reset mechanisms. Rename qemu_prep_reset() to qemu_reboot() and change the function to immediately reboot after the code memcpy. This fixes a bug that could cause code corruption on reboots - calling the udelay() function (as invoked by i8042_reboot and/or pci_reboot) was not valid after the BIOS was memcpy'd.

* smp: restore MSRs on S3 resumePaolo Bonzini2016-07-071-0/+1
| | | | | | | | | | | | | | | | | Currently the MTRRs and MSR_IA32_FEATURE_CONTROL are not restored on S3 resume. Because these have to be applied to all processors, SMP setup has to be added to S3 resume. There are two differences between the boot and resume paths. First, romfile_* is not usable in the resume paths so we separate out the remaining common code to a new smp_scan function. Second, smp_msr has to be walked on the BSP as well, so we extract that out of handle_smp and into a new function smp_write_msrs. Then, resume can call smp_write_msrs on the BSP followed by smp_scan to initialize the APs.

* post: Always set HaveRunPost prior to setting any other global variableKevin O'Connor2016-01-121-0/+1
| | | | | | | | | | | The HaveRunPost flag controls whether post or reboot handling is entered on a reset signal. The flag needs to be set before any other global variable because an external reboot signal could occur at any time. (If any global variable is modified prior to setting HaveRunPost then the code might enter post with global variables in a dirty state.) Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* tpm: Add a menu for TPM configurationStefan Berger2015-12-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an new menu entry to the main menu. This menu item enables the user to enter a TPM control menu which allows control of those aspects of the TPM's state that can only be controlled while in the firmware and while physical presence can be asserted. If the machine has a TPM, the boot menu will look as follows, with the new menu item accessible by pressing the 't' key. Select boot device: 1. ata0-1: QEMU HARDDISK ATA-7 Hard-Disk (6144 MiBytes) 2. Legacy option rom 3. iPXE (PCI 00:03.0) t. TPM Menu Upon pressing t the TPM submenu will be shown: The Trusted Platform Module (TPM) is a hardware device in this machine. It can help verify the integrity of system software. The current state of the TPM is: Enabled and active Ownership has not been taken A user can take ownership of the TPM Available options are: d. Disable the TPM v. Deactivate the TPM p. Prevent installation of an owner If no change is desired or if this menu was reached by mistake, press ESC to reboot the machine. The TPM menu only shows those options that are currently accessible considering the state of the TPM. The patch adds several functions for sending those messages to the TPM required for supporting those menu items. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

| | | | | | | | | | 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.

* Add multiboot support.Vladimir Serbinenko2015-06-011-0/+3
| | | | | | | | | | | | | | | | | | | | 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 Berger2015-05-211-0/+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.

* If an int 1587 call is made from an option rom, stay in bigreal mode.Kevin O'Connor2014-05-061-0/+1
| | | | | | | | | | | Modify the int 1587 handler to check if the POST phase is still running. If it is, use bigreal mode segment limits so that the caller remains in bigreal mode when the 1587 handler completes. This helps with SeaVGABIOS' use of "direct" framebuffer accesses (an option rom may attempt to display text during its option rom execution which can cause SeaVGABIOS to make the int 1587 calls).

* resume: restore piix pm config registers after resumeMarcel Apfelbaum2014-01-151-0/+1
| | | | | | | | | | | | | | | | 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.
