2005-11-08[PATCH] AGP performance fixesAlan Hourihane
AGP allocation/deallocation is suffering major performance issues due to the nature of global_flush_tlb() being called on every change_page_attr() call. For small allocations this isn't really seen, but when you start allocating 50000 pages of AGP space, for say, texture memory, then things can take seconds to complete. In some cases the situation is doubled or even quadrupled in the time due to SMP, or a deallocation, then a new reallocation. I've had a case of upto 20 seconds wait time to deallocate and reallocate AGP space. This patch fixes the problem by making it the caller's responsibility to call global_flush_tlb(), and so removes it from every instance of mapping a page into AGP space until the time that all change_page_attr() changes are done.

2005-10-24[AGPGART] Set .owner field of struct pci_driver.Dave Jones
From: Laurent Riffard <laurent.riffard@free.fr> This updates .owner field of struct pci_driver. This allows SYSFS to create the symlink from the driver to the module which provides it. $ tree /sys/bus/pci/drivers/agpgart-via/ /sys/bus/pci/drivers/agpgart-via/ |-- 0000:00:00.0 -> ../../../../devices/pci0000:00/0000:00:00.0 |-- bind |-- module -> ../../../../module/via_agp |-- new_id `-- unbind Signed-off-by: Laurent Riffard <laurent.riffard@free.fr> Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org>
2005-07-29[PATCH] agp: restore APBASE after setting APSIZEMatthew Garrett
When leaving S3 state, the AGP bridge may not have all PCI configuration registers set in the same way as they were at boot. This should be fixed by pci_restore_state - however, the APBASE register cannot be set to conflict with the APSIZE register. If APSIZE is larger than it was before suspend, pci_restore_state will not restore APBASE correctly. The attached patch adds an extra item to the agp_bridge_data structure and uses it to store the value of APBASE. On resume, this is then written after APSIZE has been set. This patch only touches the path used for Intel chipsets without integrated graphics, and may need to be extended to work with the others. Without this patch, I get the symptoms described in bug 4921 - APBASE ends up overlapping various PCI devices, and as a result they fail to work after resume.

2005-06-07[PATCH] AGP fix for Xen VMMKeir Fraser
When Linux is running on the Xen virtual machine monitor, physical addresses are virtualised and cannot be directly referenced by the AGP GART. This patch fixes the GART driver for Xen by adding a layer of abstraction between physical addresses and 'GART addresses'. Architecture-specific functions are also defined for allocating and freeing the GATT. Xen requires this to ensure that table really is contiguous from the point of view of the GART. These extra interface functions are defined as 'no-ops' for all existing architectures that use the GART driver.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
