New patch to review for coreboot: 66ebaa9 Respect linker order
by Christian Ruppert 17 Dec '11

17 Dec '11

Christian Ruppert (idl0r(a)qasl.de) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/494 -gerrit commit 66ebaa9f670438b7dd4efa80b65830b362729a9b Author: Christian Ruppert <idl0r(a)qasl.de> Date: Sat Dec 17 21:56:05 2011 +0100 Respect linker order Linking fails when using -Wl,--as-needed and/or esp. when forcing --as-needed through a compiler specs file. A proper compile/link command would look like: $(CC) $(CFLAGS) $(LDFLAGS) -o foo $(OBJS) $(LIBS). So the *FLAGS must be passed *before* the objects while the libraries/dependencies must be passed *after* the objects.

New patch to review for coreboot: b751de8 Persimmon audio codec verb patch.
by Marc Jones 17 Dec '11

17 Dec '11

Marc Jones (marcj303(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/490 -gerrit commit b751de894b1a7126b5182fefb9e048c5ffc45597 Author: Marc Jones <marcj303(a)gmail.com> Date: Wed Dec 14 11:24:00 2011 -0700 Persimmon audio codec verb patch. Verb data is required for the HDA audio codec in the sb800 southbridge. Verb data is not required for mainboards that use G-Series HDMI. It is also a setting the may be boards specific. This fixes issues with Windows audio on Persimmon.

16 Dec '11

Hi all, I'm learnning the coreboot v4 source code. But when I read the file entry32.inc, I don't know where the execution will jmp to after the __protected_start. I need help. BRs, Rock.

Patch set updated for coreboot: 23660d2 Fix multipleVGA cards resource conflict on Windows
by Kerry Sheh 16 Dec '11

Kerry Sheh (shekairui(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/489 -gerrit commit 23660d2e26e4c63b8b2eca3c59d3bf756acadf5d Author: Kerry Sheh <shekairui(a)gmail.com> Date: Fri Dec 16 11:58:47 2011 +0800 Fix multipleVGA cards resource conflict on Windows If both legacy graphic cards decode the IO range 3B0-3DF and MEM range A00000-BFFFF, Windows 7 complain a resource conflict, so only one VGA card can works at the same time. There is a discuss in coreboot mail list before, please reference thread: "how to prevent legacy resource conflictwith multipleVGA cards" Linux using VGA Arbiter module(vgaarb) to resolve this resource conflict, Please see the following linux dmesg log, more information can be found in Linux source dir Documentation/vgaarbiter.txt.

ASUS P5KPL-AM Let's play
by nap 15 Dec '11

15 Dec '11

Let's play and contribute... Comments welcome. The motherboard is a vanilla G31/ICH7 microATX with a LGA775 socket and an accessible socketed DIP8. See: http://www.asus.com/Motherboards/Intel_Socket_775/P5KPLAM/ The CPU is currently a Pentium E5300. I have cloned the coreboot git tree and started to play with Kconfig and read the code, to add the pieces for the support of the ASUS P5KLM-AM board, if possible. I have got the MB/CPU/NB/SB datasheets. My immediate goal is to get some debug complaints from a coreboot image. >From a first browsing of the supported motherboards, I have found the LENOVO T60 laptop as the nearest from a CPU/chipset perspective 945GM/ICH7, but I suppose I will probably need to get pieces from an ATX MB. I have put a renamed copy of the T60 in the motherboards/ASUS folder. My current problems are, starting from the intel/model_f4x: what is a cpu_device_id (seems like a pci id) ? how to get the cpu_device_id(s) to put in cpu_table ? how is derived the cpu/intel/model name from them ? how to properly set the include and microcode list ? how to get the proper microcode ? how to name the 775 socket, maybe LGA775 ? Enough for now. nap
