[PATCH] tcgbios: Fix details in log entries
by Stefan Berger 30 Jun '21

30 Jun '21

Fix two details of the logs: - Set the field 'SpecErrata' to 2 as required by specs. - Write the separator into the log entry's event field.

[PATCH 0/2] tcgbios: Use the proper hashes for the TPM 2 PCR banks
by Stefan Berger 30 Jun '21

30 Jun '21

This PR adds the implementations for sha{256, 384, 512} and makes use of the hash implementation when extending the PCRs of the respective banks rather than always using the sha1 and zero-padding it for the PCR banks of a TPM 2.

Re: INT 14H
by Paul Edwards 28 Jun '21

Hi Peter. Thanks for your reply. > Sure. Implement a driver for that redirection which behaves as an > int14h handler and place the address of its entry point at address > 0000:0080. (14h*4) > The method works with any BIOS. I would like it to work with any OS that uses INT 14H (regardless of how many of those exist), rather than any BIOS. For now I am happy if it only works with SeaBIOS, and I will simply buy a PC that allows me to flash SeaBIOS onto it. Other manufacturers can do other things with INT 14H, redirecting it to some other device, such as HAM radio. > If suitable for your hardware you could do all of it in an option ROM. I'm not familiar with this terminology. Is this something that goes into SeaBIOS? I'm expecting it to be something that is set up (and even configured by the end user in the BIOS) before my OS is even loaded. Thanks. Paul.

INT 14H
by Paul Edwards 28 Jun '21

28 Jun '21

Hi. INT 14H is designed to read/write to a serial port. I would like my software (OS) that uses this interface to, on a machine that doesn't have a serial port, be directed to some other device, like bluetooth to my phone or Wifi to my router. Is this possible? Thanks. Paul.

[PATCH v4 0/2] fix PS/2 keyboard initialization failures
by Volker Rümelin 09 Jun '21

09 Jun '21

Hi, I wrote a few patches for qemu [1] and patch 10/11 exposes a bug in seabios. Sometimes the PS/2 keyboard initialization fails and seabios doesn't detect the keyboard. This patch fixes the PS/2 keyboard initialization. I wouldn't be surprised if my patch also fixes PS/2 keyboard initialization problems on bare metal. A few bug reports look very similar to what I see on my computer with qemu. With best regards, Volker v2: Kevin suggested to call check_irqs() in run_thread(). v3: Add a new patch to fix the asm constraints in run_thread(). The changes are required for the next patch. Kevin suggested to call check_irqs() after the new thread ran in run_thread(). Fixed an error in the commit message. Call check_irqs() after switch_next() in yield(). v4: Drop the patch to fix the asm constraints in run_thread(). Rename cur to edx in the asm constraints in run_thread() to make it clear that edx is clobbered after the asm statement.

[PATCH v3] Increate BUILD_MIN_BIOSTABLE for large roms
by Gerd Hoffmann 04 Jun '21

04 Jun '21

BUILD_MIN_BIOSTABLE reserves space in the f-segment. Some data structures -- for example disk drives known to seabios -- must be stored there, so the space available here limits the number of devices seabios is able to manage. This patch sets BUILD_MIN_BIOSTABLE to 8k for bios images being 256k or larger in size. 32bit code is moved off in that case, so we have more room in the f-segment then.

[PATCH 0/1] stacks: disable NMIs during state restore on call32_post()
by Heitor Alves de Siqueira 01 Jun '21

01 Jun '21

Hi all, We've had reports of users hitting KVM emulation failures in certain workloads and were able to track down a missing NMI_DISABLE_BIT in call32_post() when accessing CMOS ports. This patch disables NMIs on state restore, following other accesses to CMOS_PORT_INDEX throughout the seabios code.
