[LinuxBIOS] PCI: 00:00.0 cmd <-146
by steve yannalfo 25 May '06

25 May '06

PCI: 00:00.0 subsytem <- 00/00 PCI: 00:00.0 cmd <-146 This is the last message i see booting LB. Everything looks OK to this point. (devices are correct BUS:Device.func) My board is similar to tyan/s2891 amdk8 LTD 0 -> CK804 -> W83627thf I have tried "getpir" to create a new irq_tables.c but it Segmentation faults after Validating. I don't know if my resourcemap.c & mptable.c is correct or where to get the proper info for them. I just copied the files from tyan/s2891. Does anyone have any suggestions? thank you. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Re: [LinuxBIOS] [OLPC-devel] Linux "bootloader" image - build instructions?

Hi Steven, Goodrich,Steven wrote: > In order to get an image I can build/test with: > Where can I find instructions and a component list for the "bootloader" > Linux image (in the ROM)? this question is best asked on the LinuxBIOS list. I think Ron Minnich has the most current ROM image for OLPC. Regards, Carl-Daniel -- http://www.hailfinger.org/

[LinuxBIOS] gcc version
by Russell Whitaker 24 May '06

24 May '06

The other day there was a comment about a gcc-3.3 bug, so ran abuild using gcc-3.4.6 on a i686-pc. Made a diff of the result with the web page's abuild log. Deleted pairs of successes. Result is attachment. Conclusion: 3.4.6 should work ok russ

[LinuxBIOS] Compressing the OLPC VSM?
by Carl-Daniel Hailfinger 24 May '06

24 May '06

Hi, the VSM Ron mailed yesterday to olpc-devel can be compressed very well to under 32 kb. 65536 vsa_test.64k-0001.bin 35587 vsa_test.64k-0001.bin.nrv2b 32143 vsa_test.64k-0001.bin.lzma Is the VSM executed after RAM is there and can we use compression for it? 50% savings are really good.

Re: [LinuxBIOS] selection of compression algorithm
by Lu, Yinghai 24 May '06

Copy_and_run is used by CAR and included in cache_as_ram_auto.c and compiled with gcc. That should be changed to use lzma easily. CONFIG_COMPRESSED_ROM_STREAM is used for pay load. --- stream_init will do the uncompressed. ( stream_init is in ram) CONFIG_COMPRESS is for linuxbios_ram.rom --- copy_and_run will do the uncompress. ( copy_and_run is ROM, and used ram as stack and local variable) You may create one file only that is corresponding to lib/nrv2b.c...

You mean copy_and_run() is compiled with romcc? Can we change that? What's the difference between CONFIG_COMPRESSED_ROM_STREAM and CONFIG_COMPRESS? Can we use lzma compression for both?

[LinuxBIOS] wiki access and commit rights
by Carl-Daniel Hailfinger 24 May '06

24 May '06

Hi, is there any process to get commit rights or are they only reserved for a core team? I'd like to work on integrating lzma compression support in the following weeks. After that, I plan to add support for a few SuperIO chips found on Asus boards. Regards, Carl-Daniel

Re: [LinuxBIOS] co processor support and other

Yes. That is very interesting... 1. Some guys is trying to use HTX connector to add co-processor card. 2. Some guys is using GPU on PCI-E... Current code treat that coproc as one extra HT chain...

( hard coded) What coprocessor is that? A Xilinx FPGA? Are 2891 delivered with those per default? Can LinuxBIOs fuel them with code now? This sounds _very_ interesting.

[LinuxBIOS] co processor support and other
by Lu, Yinghai 22 May '06

22 May '06

Just check in 1. r2308: Option CONFIG_CONSOLE_VGA_ONBOARD_AT_FIRST It decides use onboard VGA or add on vga adapter 2. r2309: reduce clear ECC time from 2.1x to 1.1x. need to enable SERIAL_CPU_INIT 3. r2310: enable ht chain for drc co processor in s2891. Please check that. Steve, I still wonder how do you init the memory on your co processor without the spd rom access. ( hard coded) Thanks Yinghai Lu
