[LinuxBIOS] r3038 build service
by LinuxBIOS information 08 Jan '08

08 Jan '08

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "hailfinger" checked in revision 3038 to the LinuxBIOS source repository and caused the following changes: Change Log: This patch is an attempt at introducing 4k CAR size granularity for the generic x86 CAR code. For the old supported CAR sizes, the newly generated code is equivalent, so it should be a no-brainer. Add a copyright header to the code, the header is derived from the one found in the same piece of code in v3. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006(a)gmx.net> Acked-by: Marc Jones <marc.jones(a)amd.com> Build Log: Compilation of amd:serengeti_cheetah_fam10 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=3038&device=serengeti_che… Compilation of tyan:s2735 has been broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=3038&device=s2735&vendor=… If something broke during this checkin please be a pain in hailfinger's neck until the issue is fixed. If this issue is not fixed within 24h the revision should be backed out. Best regards, LinuxBIOS automatic build system

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS.

Normalize used locale to "C" before parsing output. Signed-off-by: Patrick Georgi <patrick(a)georgi-clan.de> Acked-by: Stefan Reinauer <stepan(a)coresystems.de> Build Log: Compilation of amd:serengeti_cheetah_fam10 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=3037&device=serengeti_che… If something broke during this checkin please be a pain in oxygene's neck until the issue is fixed. If this issue is not fixed within 24h the revision should be backed out. Best regards, LinuxBIOS automatic build system

Well, I had thought PCI SIG had stopped this nonsense, but the PCIe spec is still "members only". Is there a .pdf *somewhere* that one can look at? thanks ron

I'm seeing the following during early initialization. Does anyone have a suggestion for what to investigate? I've moved to a new board (first proto). This has BSP to AP on BSP link 1 and AP to BSP on AP link 2. (0,1) link=02 (1,0) link=01 02 nodes initialized. core0 started: 01 01 02 03SBLink=01 NC node|link=01 NC node|link=12 busn=40 fidvid_ap_stage1: time out while reading from BSP on 02 fidvid_ap_stage2: time out while reading from BSP on 02 fidvid_ap_stage3: time out while reading from BSP on 02 Thanks, Steve fyi: custom board with two Opterons and Broadcom chipset.

Hi, all, In PCI, the IDSEL pin defines the device number. But in PCIe, there is no such pin, how is the device number defined? Best Regards 丰立波 Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010-62801406
