Does linux kernel parse linuxbios table?
by Liu Tao 14 Jan '05

14 Jan '05

Hello Eric, I searched the linux kernel mail archive and found your patch for x86 boot linuxbios support, but I didn't find the linuxbios table parse code in linux-2.6.8.1, does linux kernel still parse the linuxbios table now? Regards, Liu Tao

No, Top to down will more worse. 1. I thank Northbridge PCI_DEV(0, 0x18, 0)... should be initial before CPU.... 2. In tree apic cluster is after pci_domain.....

It seems after if after cpu init do the onboard vga init, it will work. The CPU init only do the init ECC and clear that after 1M. ... Werid! And it is not wiped out after power off.

I would change dev_initalize to following void dev_initialize(void) { struct device *dev; printk_info("Initializing devices...\n"); #if CONFIG_CONSOLE_VGA == 1 for (dev = all_devices; dev; dev = dev->next) { if (dev->enabled && !dev->initialized && dev->ops && dev->ops->init) { if( dev->on_mainboard && (dev->rom_address!=0)) continue; printk_debug("%s init\n", dev_path(dev)); dev->initialized = 1; dev->ops->init(dev); } } #endif for (dev = all_devices; dev; dev = dev->next) { if (dev->enabled && !dev->initialized && dev->ops && dev->ops->init) { printk_debug("%s init\n", dev_path(dev)); dev->initialized = 1; dev->ops->init(dev); } } printk_info("Devices initialized\n"); } -----Original Message----- From: YhLu Sent: Thursday, January 13, 2005 6:51 PM To: Li-Ta Lo Cc: Sagiv Yefet; LinuxBIOS Subject: RE: Running with VGA It seems after if after cpu init do the onboard vga init, it will work.

Re: problem with booting SMP linux kernel
by Gin 13 Jan '05

I've adjusted my MP table to use the correct IRQs. But the IDE interrupt is still lost. There is some message from linux kernel that I didn't understand. Is there something wrong with my timer settings? ================================================================ ..MP-BIOS bug: 8254 timer not connected to IO-APIC ...trying to set up timer (IRQ0) through the 8259A ... ..... (found pin 0) ... failed. ...trying to set up timer as Virtual Wire IRQ... works. =============================================================== This is the last line where the kernel stops. ================================================================= hda:<4>hda: dma_timer_expiry: dma status == 0x24 ================================================================= Does anyone have an idea? gin

No, no problem. Same addon card (ati rage xl) (pci) on S2895 works well.

It seems that onboard ATI rage xl font mem can not be loaded correctly by option rom in emulator. After load the kernel (2.6.5) with atyfb enabled. The font mem can be recovered even restart the MB. I guess the ati rage xl could be judge sth to decide if it need to reload the font mem.

That resource is dummy so it should not be process by the resource allocator. Anyway, probably we should give up (ab)using the allocator. I made another version to use dev->rom_address in pci_rom_probe().

I have done some interesting test. I plug one display adapter to the MB, and let linuxbios excute onboard vga option rom at first, and then option rom in addon card. Then power down and I unplug the add on card At last boot the system, after linuxbios, it works well. The option rom in Adapter init the Font Mem and it can last some time even power off the MB....Funny..... YH
