* agp: Support 64-bit APBASEBjorn Helgaas2014-01-061-2/+2
| | | | | | | | | | | | Per the AGP 3.0 spec, APBASE is a standard PCI BAR and may be either 32 bits or 64 bits wide. Many drivers read APBASE directly, but they only handled 32-bit BARs. The PCI core reads APBASE at enumeration-time. Use pci_bus_address() instead of reading it again in the driver. This works correctly for both 32-bit and 64-bit BARs.

* Drivers: char: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-2/+1
| | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* agp: use scratch page on memory remove and at GATT creation V4Jerome Glisse2010-04-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Convert most AGP chipset to use scratch page as default entries. This help avoiding GPU querying 0 address and trigger computer fault.

* AGP fix race condition between unmapping and freeing pagesDave Airlie2007-10-151-11/+16
| | | | | | | | | | | | | With Andi's clflush fixup, we were getting hangs on server exit, flushing the mappings after freeing each page helped. This showed up a race condition where the pages after being freed could be reused before the agp mappings had been flushed. Flushing after each single page is a bad thing for future drm work, so make the page destroy a two pass unmapping all the pages, flushing the mappings, and then destroying the pages.

* [AGPGART] Allow drm-populated agp memory typesThomas Hellstrom2007-02-031-0/+2
| | | | | | | | | | | | | | | | | | | | This patch allows drm to populate an agpgart structure with pages of its own. It's needed for the new drm memory manager which dynamically flips pages in and out of AGP. The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is currently the only one supporting the new memory manager. Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver. AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected to do that, as well as taking care of cache- and tlb flushing when needed. It's not possible to request these types from user space using agpgart ioctls. The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

* | [PATCH] fix missing includesTim Schmielau2005-10-301-0/+1
|/ | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] AGP fix for Xen VMMKeir Fraser2005-06-071-2/+2
| | | | | | | | | | | | | | | | | | | 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.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+414
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!
