[LinuxBIOS] patch: alix1c support for v3
by ron minnich 27 Nov '07

27 Nov '07

This builds. It will not work. But I want this code backed up somewhere, not just on my laptop.I also want other people to see it and add corrections, if needed. The alix1c will use the fake spd array. A lot of support can come across from the v2 port. ron

[LinuxBIOS] r2988 build service
by LinuxBIOS information 27 Nov '07

27 Nov '07

Dear LinuxBIOS readers! This is the automated build check service of LinuxBIOS. The developer "uwe" checked in revision 2988 to the LinuxBIOS source repository and caused the following changes: Change Log: Drop the unfinished, non-working Bitworks IMS board. It never worked in v2 (the v1 port did work AFAIK, though), and it's not really useful as reference for other boards anymore (as we now have a dozen or so 440BX boards which work in v2). This is a specialized, custom board (not sold on the "public market"), so it's probably not useful for pretty much everyone out there anyway. We can easily re-add it later (based on one of the other 440BX boards) should there be interest and/or someone with the hardware to test. Signed-off-by: Uwe Hermann <uwe(a)hermann-uwe.de> Acked-by: Jordan Crouse <jordan.crouse(a)amd.com> Build Log: Compilation of msi:ms9185 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2988&device=ms9185&vendor… Compilation of msi:ms9282 is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2988&device=ms9282&vendor… Compilation of supermicro:h8dmr is still broken See the error log at http://qa.linuxbios.org/log_buildbrd.php?revision=2988&device=h8dmr&vendor=… If something broke during this checkin please be a pain in uwe'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

[LinuxBIOS] v3: make initram work
by Carl-Daniel Hailfinger 27 Nov '07

27 Nov '07

This is my current v3 diff against r518. It has endianness and 64bit bugs, but it makes initram work correctly for a modified qemu target. Other half-related changes are mixed in as well. Look at mainboard/emulation/qemu-x86/Makefile to see the changes needed for initram for all targets. Maybe we should move these changes to arch/x86/Makefile.

[LinuxBIOS] v3: an interesting problem with initram
by ron minnich 27 Nov '07

27 Nov '07

Initram is being set up as follows: 08048074 T spd_read_byte 080480e0 T main 08048145 T __i686.get_pc_thunk.bx 0804814c t helper_calc 08048199 T hcf 080481bd T banner 080481f6 t helper_spd 08048248 t auto_size_dimm 08048451 T sdram_set_spd_registers 08048a32 T sdram_set_registers 08048a89 T sdram_enable 08048c4c T system_preinit 08048c55 T geode_link_speed 08048c80 T pll_reset 08048d4c T pci_speed 08048d62 T cpu_speed 08048d8c T cpu_reg_init 08049000 r spdbytes 08049222 r num_col_addr 08049232 r CASDDR 0804923a r REFRESH_RATE 080492e0 r msr_table 08049320 r delay_control_table 080493c0 d _GLOBAL_OFFSET_TABLE_ 080493cc D post_code 080493d0 D printk 080493d4 A __bss_start 080493d4 A _edata 080493d4 A _end note that spd_read_byte is first. And it's entered first and that's bad, as main is supposed to be entered. I tried the simple thing of reordering the functions in the file, and that did not do it. So, why is spd_read_byte first in the file, and how do we fix it? Because the call from the rom code is going to spd_read_byte, not main, and I'm stuck :-) but wow, it's close! ron
