[LinuxBIOS] [RFC] i82801 generic patch
by Corey Osgood 30 Dec '07

30 Dec '07

The attached patch is a unified version of the current ports of the i82801 series currently in LinuxBIOS. Since most of the ports are nearly identical, I've taken for each file and chosen the cleanest or best version of the code, then checked over the datasheets to *some* of the series, including the aa, ba, ca, and db, to make sure that it would work. I've also made some changes here and there, mostly cleanup and clarification. The only things left to look at are the huge difference between this version's lpc init and the i82801er's, finding a better way to select which chip is present on the board, and gpl headers in all files. Anyways, comments, suggestions, even flames are welcome ;) Testing on other chips can be done at this point as well, this is tested and working on one model, the i82801aa. -Corey

[LinuxBIOS] [PATCH] IDE legacy port access + UDMA/33 for 440BX boards
by Uwe Hermann 17 Dec '07

17 Dec '07

See patch. At the very least the IDE legacy port access must be enabled to be able to use FILO. The rest is optional, but I see no reason to not enable it per default.

[LinuxBIOS] [BUILDROM] Add support for the AMD SimNow (TM) simulator (try 2)
by Jordan Crouse 13 Dec '07

13 Dec '07

Here is the refreshed patch for the SimNow support against current RCS. Something is triggering my bat sense that the tree isn't exactly in a right state, but I can't remember what it is. Please test the tree with and without the patch to make sure that its sane. Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc.

[LinuxBIOS] [PATCH] TeleVideo TC7020 support
by Kenji Noguchi 09 Dec '07

09 Dec '07

Hi Attached is a patch for TeleVideo TC7020 support. It should work fine with r2993. Please kindly review. Large part of the patch is just a duplicate of BCOM Winnet100 patch hence many files retain copyright holder as Juergen Beisert. My TC7020 runs Debian's unmodified kernel 2.6.18, and mount /var /home /root and /tmp on /dev/shm/{var,home,root,tmp} so that the Compact Flash drive remains read-only. No worries of wear and tear, and clean shutdown. I will see how MythTV performs on this box. DirectFB already runs nicely. Does anyone know if GX1 MPEG decoder is supported by video4linux? Regards, Kenji Noguchi p.s. Sorry Uwe that I missed your email asking for the status.

[LinuxBIOS] [PATCH] many trivial patches
by Myles Watson 09 Dec '07

09 Dec '07

This adds the same line (uses CONFIG_PRECOMPRESSED_PAYLOAD) to every Options.lb file that already had a "uses CONFIG_COMPRESSED_PAYLOAD_LZMA" line in it. I figure that only adding it to the files that already have support for LZMA payloads makes sure I don't break anything. Myles Signed-off-by: Myles Watson <myles(a)pel.cs.byu.edu>

[LinuxBIOS] alix1c patch for irq.
by ron minnich 08 Dec '07

08 Dec '07

With this patch, I think the IRQ situation is basically fixed, though Ingmar may not agree once he tests it. i would like to try to standardize on these cards for V3 porting. They are cheap, the vendor support is great (AMD and PC Engines), and they are easy to debug. I'd like to see if those of you working on v3 could take a look at this card. V3 is going to go lots faster if we are on common hardware. ron
