2009-03-01Some changes required to get yabel working on v2 (and they generally makeStefan Reinauer
sense, too). Have one u64 instead of three. In order to use the old bios emulator, you have to do nothing. (Default, if CONFIG_PCI_ROM_RUN is enabled) In order to use yabel in your target, you need to add the following lines to your config: uses CONFIG_PCI_OPTION_ROM_RUN_YABEL default CONFIG_PCI_OPTION_ROM_RUN_YABEL=1 In order to use vm86 in your target, you need to add the following lines to your config: uses CONFIG_PCI_OPTION_ROM_RUN_VM86 default CONFIG_PCI_OPTION_ROM_RUN_VM86=1 Note: vm86 only works on platforms with _RAMBASE in the lower megabyte.

2008-07-23This patch fixes the kernel EBDA mislocation problem. Thank you, Yinghai.Roman Kononov
The change in tables.c protects the legacy x86 BIOS data segment (0x400-0x4ff) from being used for storing coreboot tables. Some bytes from the segment are used by the kernel and should not be garbled. The change in coreboot_table.c is not strictly necessary. It removes some redundancy and confusion.

2008-03-29Now coreboot performs IRQ routing for some boards.Nikolay Petukhov
You can see this by executing commands like this: grep -r pci_assign_irqs coreboot/src/* This basically AMD/LX based boards: pcengines/alix1c, digitallogic/msm800sev, artecgroup/dbe61, amd/norwich, amd/db800. Also for AMD/GX1 based boards need a patch [http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch] for the right IRQ setup. AMD/GX1 based boards is: advantech/pcm-5820, asi/mb_5blmp, axus/tc320, bcom/winnet100, eaglelion/5bcm, iei/nova4899r, iei/juki-511p. I have two ideas. 1. Delete duplicate code from AMD/LX based boards. 2. Add IRQ routing for AMD/GX1 boards in coreboot. The pirq.patch for IRQ routing logically consist from of two parts: First part of pirq.patch independent from type chipsets and assign IRQ for ever PCI device. It part based on AMD/LX write_pirq_routing_table() function. Second part of pirq.patch depends of type chipset and set PIRQx lines in interrupt router. This part supports only CS5530/5536 interrupt routers. IRQ routing functionality is included through PIRQ_ROUTE in Config.lb. Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on TeleVideo TC7020, see http://www.coreboot.org/pipermail/coreboot/2007-December/027973.html.

Linuxbios boots an Opteron motherboard with 1GB memory. Linuxbios directly loads a recent linux kernel. The memory layout is like this: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved) BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable) BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable) BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved) BIOS-e820: 00000000000f0400 - 0000000040000000 (usable) The f0000-f0400 region contains IRQ and ACPI tables. At some point the kernel builds a resource table containing all physical address ranges and type of hardware the addresses are mapped to. The table is accessible via /proc/iomem: # cat /proc/iomem 00000000-00000e17 : reserved 00000e18-0009ffff : System RAM 000a0000-000bffff : Video RAM area 000c0000-000cbfff : Video ROM 000f0000-000fffff : System ROM e0000000-efffffff : PCI Bus #03 e0000000-efffffff : 0000:03:00.0 f0000000-f3ffffff : GART f4000000-f60fffff : PCI Bus #03 f4000000-f4ffffff : 0000:03:00.0 f5000000-f5ffffff : 0000:03:00.0 f6000000-f601ffff : 0000:03:00.0 f6100000-f6100fff : 0000:00:01.0 f6101000-f6101fff : 0000:00:02.0 f6101000-f6101fff : ohci_hcd f6102000-f6102fff : 0000:00:04.0 f6103000-f6103fff : 0000:00:07.0 f6103000-f6103fff : sata_nv f6104000-f6104fff : 0000:00:08.0 f6104000-f6104fff : sata_nv f6105000-f6105fff : 0000:00:0a.0 f6106000-f61060ff : 0000:00:02.1 f6200000-f620ffff : 0000:40:01.0 As you can see, the 00000000000f0400-0000000040000000 region is not listed. It is not listed because the kernel unconditionally adds "000f0000-000fffff : System ROM" first (look for "request_resource(&iomem_resource, &system_rom_resource)"), and then the attempt to add f0400-40000000 range fails because of overlapping. The kernel does not care that the range is not listed there. Kexec does. It uses the /proc/iomem file to instruct the kexec system call how to place the segments of a new kernel in the physical memory. Kexec fails to start a new kernel because it cannot locate enough physical memory. This must be fixed either in linux or linuxbios. Assuming that linuxbios is to be fixed, I cooked a patch which provides this memory layout: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved) BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable) BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000040000000 (usable) The /proc/iomem contains: # cat /proc/iomem 00000000-00000e17 : reserved 00000e18-0009ffff : System RAM 000a0000-000bffff : Video RAM area 000c0000-000cbfff : Video ROM 000f0000-000fffff : System ROM 00100000-3fffffff : System RAM 00100000-00203c61 : Kernel code 00203c62-00248c3f : Kernel data e0000000-efffffff : PCI Bus #03 e0000000-efffffff : 0000:03:00.0 f0000000-f3ffffff : GART f4000000-f60fffff : PCI Bus #03 f4000000-f4ffffff : 0000:03:00.0 f5000000-f5ffffff : 0000:03:00.0 f6000000-f601ffff : 0000:03:00.0 f6100000-f6100fff : 0000:00:01.0 f6101000-f6101fff : 0000:00:02.0 f6101000-f6101fff : ohci_hcd f6102000-f6102fff : 0000:00:04.0 f6103000-f6103fff : 0000:00:07.0 f6103000-f6103fff : sata_nv f6104000-f6104fff : 0000:00:08.0 f6104000-f6104fff : sata_nv f6105000-f6105fff : 0000:00:0a.0 f6106000-f61060ff : 0000:00:02.1 f6200000-f620ffff : 0000:40:01.0 Kexec is happier with the patch.

Default is 255. This allows mainboard configs for working across various groups of boards that differ a device that may not loaded. If you search for a device that is not loaded and max buses is 255 then there can be up to a 8 second delay to search the entire PCI space. Board configs that know thier max bus can limit this search space. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2273 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
