#76: LinuxBIOS messages should be accessible in dmesg ----------------------------+----------------------------------------------- Reporter: stepan | Owner: rminnich Type: enhancement | Status: new Priority: major | Milestone: Setting up LinuxBIOS v3 Component: coreboot | Version: v3 Resolution: | Keywords: Dependencies: | Patchstatus: there is no patch ----------------------------+----------------------------------------------- Comment (by anonymous): No. The code in r590 only creates infrastructure within coreboot. Someone on the uboot mailing list stated that you have to change the linux kernel to know where to look for the buffer (and potentially check the format, not sure). This (at least a pointer to the log) should be passed in the coreboot table. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/76#comment:3> coreboot <http://www.coreboot.org/>

PCI irq routing
by Nikolay Petukhov 01 Apr '08

01 Apr '08

Hi, all. Now coreboot perform irq routing for some boards. 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-5…] for the right setup irq. 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.part depends of type chipset and set PIRQx linies in interrupt router. Now this part supports only CS5530/5536 interrupt routers. Irq routing functionality is include through macro PIRQ_ROUTE in Config.lb. Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on TeleVideo TC7020 http://www.coreboot.org/pipermail/coreboot/2007-December/027973.html. -- Nikolay

Issue tracker -- list issues by component
by Uwe Hermann 01 Apr '08

01 Apr '08

Hi, I've added a new "report" to trac which allows you to view issues sorted by component: http://tracker.coreboot.org/trac/coreboot/report/10 I've also re-assigned a few issues to their proper component as good as I could, but some may still need to be re-arranged. There are now components for pretty much all relevant parts of the coreboot "family", including filo, grub2, coreinfo, libpayload, coreboot (v2 or v3), mkelfimage, flashrom, superiotool, wiki/website/tracker, toolchain etc. If you think a component is missing, please let me know so I can add it. Thanks, Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org
