Re: [SeaBIOS] [coreboot] Upgrade the 12 years old LZMA libraries - should we do it?

Do you have any numbers for this? An improved compression ratio and improved speed would be nice indeed, but how does the size of the decompression code change? If the decompression code grows more than the size reduction from better compression, it would be a net loss. A significantly reduced decompression speed would also be a problem. Decompression speed would have to be measured both for stream decompression (i.e. the decompressor gets the compressed data in single-byte or multibyte chunks) as well as full-size decompression (i.e. the decompressor can access all compressed data at once). We also have to make sure that stream decompression still works after the change. > Do you think it should be done, or you are OK with using such an > outdated version? A size benefit for the resulting image is a good reason to switch. Regards, Carl-Daniel

TPM 2.0 with SeaBIOS
by Piotr Kubaj 01 Aug '18

01 Aug '18

Hi, I use SeaBIOS 1.11.2 as payload with 4.8-835-g113f670baa on ASUS KGPE-D16 board. I also have ASUS TPM-L R2.0 module with Infineon SLB9665 chip. TPM is correctly detected by both Linux and FreeBSD. It's also detected by coreboot in debug console. But SeaBIOS doesn't cooperate with it - there's no TPM menu. In serial console, I get: TCGBIOS: Detected a TPM 1.2. rsdp=0x000f1930 rsdt=0xbf4b9030 table(41504354)=0xbf4bf460 TCGBIOS: Starting with TPM_Startup(ST_CLEAR) Return from tpm_simple_cmd(99, 1) = 1e TCGBIOS: TPM malfunctioning (line 874). Return from tpm_simple_cmd(73, 0) = 1e Note that SeaBIOS detects it as TPM 1.2, even though it's TPM 2.0. -- _________________________________________ / I find this corpse guilty of carrying a \ | concealed weapon and I fine it $40. | | | | -- Judge Roy Bean, finding a pistol and | | $40 on a man he'd | | | \ just shot. / ----------------------------------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||

Libvirt lets you specify the desired firmware in the domain XML: https://libvirt.org/formatdomain.html#elementsOSBIOS In this case, it should be <os> <loader>/path/to/your/bios.bin</loader> </os> Thanks Laszlo

The list of runtime SeaBIOS settings is at: https://www.seabios.org/Runtime_config You could try playing with the etc/pci-optionrom-exec setting. See QEMU's -fw_cfg command line option. You'll need to pass in a binary integer zero or binary integer one to control that setting. -Kevin

Marvell 88SE9230 passthrough in KVM takes long time to boot
by Konrad Eisele 29 Jul '18

29 Jul '18

I'm passing through a Marvell 88SE9230 card to a KVM guest under Ubuntu 18.04. The card is a Sata controller with 4 ports. The option rom of the Marvell 88SE9230 card shows on a normal boot a bios screen. When pressing CTRL-m quick enough, you can interrupt the bootprocess and enter a menue wherer you can define raid arrays. When booting seabios inside KVM the bootprocess is very slow. There is a 1 min holdtime where the cpu is about 30%. The screen is black with only the seabios version string shown. I suspect that the passed-through Marvell 88SE9230 cards option roms causes this behaviour. Maybe the scanning for option rom cause the slow bootprocess? In the seabios boot case no bios menue is shown, after around 1 min the boot continues. Is it possible to disable the options rom processing? Is there some documentation about this (How can I configure it for Ubuntu) ? // Greetings Konrad

Use a descriptive subject and include all necessary information like version, log files and the configuration. Note, that there is no guarantee to get an answer or that your problem will be solved. For that to happen, you need to be support from your distribution and use the distribution channels, like the Red Hat bug tracker [1] for Red Hat, to get it fixed. (Not to mention, that your company and you should somehow spend money on free software nevertheless, if you use it, so that the developers can afford a living and work on the project.)

hotplug failure issue on pci-bridge
by Liu, Jing2 19 Jul '18

19 Jul '18

Hi, Recently, we tried some hotplug issues. The case is: when hotplug a device (e.g. iGPU) onto pci-bridge after guest booting up, guest reports "BAR 2: no space for [mem size 0x40000000 64bit pref]" etc. Seabios checks all the devices under the pci-bridge when qemu launching the guest, and only allocates "size=ALIGN(sum, align)" of memory space for pci-bridge mem and pref-mem windows. So if we hotplug a big pci device like Intel GPU which needs 256M mem/pref-mem or bigger, it will fail. If my understanding is right, we may need some other logic of the memory allocation in seabios? Looking forward to the advice. Thanks, Jing

seabios fails to build with current IASL
by Vivia Nikolaidou 12 Jul '18

Hi, Thanks for taking action on this bug that I reported. This is a follow-up from https://mail.coreboot.org/pipermail/seabios/2018-July/012353.html - I just subscribed to the mailing list and I don't have an easy way to reply to that email directly. On Mon, Jul 02, 2018 at 09:10:34AM +0200, Gerd Hoffmann wrote: > > If you don't want use the prebuilt tables I think the sane options are > (a) use a older iasl compiler, or (b) flip ACPI_DSDT to "n" and drop > support for qemu 1.3 + older. Since (a) isn't an option in Debian, I tried going for (b) (did it directly in debian/rules when generating .config, without adding a patch for it). It still failed to compile without the patch that truncates the Table ID in the DefinitionBlock. Removing the prebuilt tables before compilation also didn't work, as they are used quite extensively in acpi.c. I'm not sure I haven't misunderstood something here, but when you say that flipping ACPI_DSDT to "n" would make it not use the prebuilt tables, what exactly do you mean? That said, would the combination of the truncating patch + flipping ACPI_DSDT to "n" be an acceptable solution to fix the build in Debian? Best regards, Vivia
