[RFC] consoles, serial ports and all that for v2 and v3 payloads
by Patrick Georgi 25 Jan '08

25 Jan '08

Hi, as promised a short proposal on how to give the payload a chance to make use of the console(s) established by coreboot. There's an ACK for my serial patch, but I'll wait for responses on this one, as the patch is a first step for this strategy. The proposal is about a setup which would implement both console management (Torsten wrote about int0x10) and resource tables (eg. serial ports at 0x400) for crucial devices. This way a payload could have a console on COM1 and get its data via PPP or ZMODEM on COM2. With only a console setup, it wouldn't know about COM2, with only a serial ports table, it wouldn't know where to find the user... The proposal is layered in two types of records: The first type is an I/O-device record, like the serial port record I wrote. These can be extended with additional information as neccessary (and independent from other device types!), which might include IRQs or enumeration (in case we ever support more than one serial port in cb itself, for example). These record are specified and designed on an as-needed basis, so we don't fall in the trap of over-engineering. Multiple devices are specified with one record (of the same type) per device, with some identifier (int) to tell them apart (added when we first use this strategy). By only adding data to the record's end, they're implicitely backward compatible, as the growing size is taken care of with the size attribute that is standard to all records. Payloads can figure out which information exists based on size as well, by ignoring any field that exceeds the size. The second type is a console type. It consists of tag and size (like every record), and an integer (enum) type that specifies the device type (eg. serial=0, vga=1, ...). Later, this record can be extended to also carry a device number (if there are multiple serial ports) and maybe priorities or markers that consoles should be used in parallel (serial + vgatext). Multiple consoles would again be done by adding one record for each console. Again, these additions will be made when there's an actual use case, thereby reducing the problem space right now. I'd like to go on with that, and will do so in a few days. Please don't wait until I have a patch ready for all that stuff, before telling me it's crap ;-) So... Comments? :-) Regards, Patrick Georgi

r560 - in coreboot-v3: northbridge/amd/geodelx util/x86emu
by svn＠coreboot.org 24 Jan '08

24 Jan '08

Author: rminnich Date: 2008-01-24 22:54:22 +0100 (Thu, 24 Jan 2008) New Revision: 560 Added: coreboot-v3/northbridge/amd/geodelx/vsmsetup.c Modified: coreboot-v3/northbridge/amd/geodelx/Makefile coreboot-v3/util/x86emu/vm86.c Log: This is a first cut at the implementation of VSM support. What has do be done, long term, is to remove almost all of the vsmsetup.c file and use functions in the vm86.c file. The barrier to achieving that goal is the specialized nature of the vga bios support code vs. the vsm bios support code. There are a few issues to resolve but what I'd like to do is get VSA working first, then work out how to merge the rest of the code. I have already done some merging at this point. This code does not yet work. But the board does not work either, and I want to get the code into the repo in case my hard drive dies. Makefile: add vmsetup.o vsmsetup.c: Add this file from v2. Fix copyright and includes. Remove almost all assembly code in favor of code in vm86.c. In future, almost all code will be removed and the vm86.c code used instead. vm86.c: make some assembly symbols .globl so that vsmsetup.c can use them. Signed-off-by: Ronald G.

Embedding VSA in a LAR
by Carl-Daniel Hailfinger 24 Jan '08

24 Jan '08

Besides the obvious stuff (storing the VSA as a file in the LAR) there are two points to solve which are rather interesting: - Entry point specification - Load address specification Both are not trivial because we get both specifications above from an ELF header. The VSA is not an ELF file, so we have to specify entry point and load address by hand. The following patch allows us to specify LAR entries like "entry=33:blobs/vsa" which then have entry point addr 33. This can be extended to a loadaddr= parameter.

Re: [LinuxBIOS] Patch file for ld/fedora 8 issue as promised...
by Marc Karasek 23 Jan '08

23 Jan '08

Here is the patch with the ld option check as well. I had to make a few changes to Ron's original patch. One of the problems was that CFLAGS was being set as a := in the Makefile and was overwriting the += that was in Makefile.settings. So I added DISTRO_CFLAGS and DISTRO_LFLAGS for the two additonal flags. The reason for two was that the build-id option is only used during linking and generated warnings if used on a compile line and was not being pulled in for the linker lines. These defines were added to the appropriate places in the Makefile via the Config.lb file. /********************* Marc Karasek MTS Sun Microsystems mailto:marc.karasek@sun.com ph:770.360.6415 *********************/ ron minnich wrote: > On Jan 3, 2008 10:33 AM, Marc Karasek <Marc.Karasek(a)sun.com> wrote: > > >> I could add the check to this patch (using awk to check ld) to add the >> -Wl option to the EXTRA_CFLAGS. >> > > cool!

[LinuxBIOS] [PATCH] Fix FireWire on GA M57 SLI-S4
by Torsten Duwe 23 Jan '08

23 Jan '08

Now I have a FireWire disk to play with. Adding an interrupt description vastly improves its performance under LinuxBIOS ;-) Potential ACKers please verify 01:0a.0 is not assigned any APIC pin so far. Comment and sign-off in the attachment. This file is quite messy. Torsten
