From: Sui Jingfeng <suijingfeng at loongson.cn> [why] The vga_is_firmware_default() defined in drivers/pci/vgaarb.c is arch-dependent, it's a dummy on non-x86 architectures currently. This made VGAARB lost an important condition for the arbitration. It could still be wrong even if we remove the #ifdef and #endif guards. because the PCI bar will move (resource re-allocation). [how]

Changes in v2: - Compute size based on ramin_rsvd_size This patch enlarges the PCI GART aperture to 512 MB, or the space covered by a DMA object filling half RAMIN. The current 64MB aperture is too small and should be enlarged. The optimal amound may be card/system-dependent, so a more sophisticated approach may be preferable. Could anyone with an nv04 test whether this doesn't break there?

On my test machine, in set_time_scale(), the following code: ts->mul_frac = div_frac(MILLISECS(1000), tps32); crashes with a division by zero error if tps32 == 1000000000d. Unfortunately, tps32 is often that value. Does anyone know why this happens? I''ve resolved it temporarily by checking for tps32 == 1000000000 and changing the value slightly (101000010d works fine on my test

Modify the cpufreq ondemand governor so that it can get idle and total ticks from the Xen hypervisor. Linux and Xen have different ideas of what an idle tick is, so the Xen values for both have to be returned in the same platform hypercall.

This patch enlarges the PCI GART aperture to 512 MB. The current 64MB aperture is too small and should be enlarged. The optimal amound may be card/system-dependent, so a more sophisticated approach may be preferable. In particular, if RAMIN is less than 1MB, a 512MB aperture won't fit.

Might want to clarify that there is no loss of functionality here. Something like: "There is no loss of functionality here. GPUs will continue to

Hi Folks, I need some large chunk of physical memory, so I allocate it early using alloc_bootmem_low_pages and use it later (akin to bigphysarea patch). The trouble I am having is the following. Suppose the virtual address for the memory area is 0xc14d6000. After xen_create_contiguous_region call, I do a virt_to_bus and the bus address comes out to be 0x18000000. So far so good. However,

I was also playing with the signed/unsigned char thing, and it solved my problem too. Although I don't understand why this could make a difference? -----Original Message----- From: Andrew Gatt [mailto:andrew.gatt@cmatic.co.uk] Sent: vrijdag 5 november 2004 11:24 To: saruman@pandora.be Cc: flac-dev@xiph.org Subject: RE: [Flac-dev] RE: basic encoder help >I'm currently facing the same

Modify the cpufreq ondemand governor so that it can get idle and total ticks from the Xen hypervisor. Linux and Xen have different ideas of what an idle tick is, so the Xen values for both have to be returned in the same platform hypercall. Otherwise, use basically the same scheme as native Linux.

Hello ! Does anybody know how to build and use cpufreq support that should be in 3.2 since -unstable time ?

Anyone had any success with or hints for a system based on the Asus P5B-VM DO board, or the Intel Q965 (with its associated Intel GMA 3000 VGA chip) in general? I had to put pci=nommconf in order to get the installer (CentOS 4.5) and the installed system to boot, but I can't get the graphics to work. Following the instructions at the Intel website

Hi, I recently subscribed to xen-users asking about a powernow-k8 problem, but in the meantime I am not sure if the users-list was the right place for it. So I decided to repeat my question here ;-) My current config is attached. --- snip --- Hi, I recently installed Xen on my AMD64 for my first time and so far, everything seems to work pretty fine. :-) I tried to enable cpu frequency

Testing by Red Hat show that changeset:0034d9389130 causes regressions on Intel machines that don''t use APIC ID lifting but that do have a strange ACPI to APIC numbering.
