* 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/+8
| | | | | | | | | | | | | | | | | | | | | | | Convert most AGP chipset to use scratch page as default entries. This help avoiding GPU querying 0 address and trigger computer fault. With KMS and memory manager we bind/unbind AGP memory constantly and it seems that some GPU are still doing AGP traffic even after GPU report being idle with the memory segment. Tested (radeon GPU KMS + Xorg + compiz + glxgears + quake3) on : - SIS 1039:0001 & 1039:0003 - Intel 865 8086:2571 Compile tested for other bridges V2 enable scratch page on uninorth V3 fix unbound check in uninorth insert memory (Michel Dänzer) V4 rebase on top of drm-next branch with the lastest intel AGP changeset (stable should use version V3 of the patch) Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Dave Airlie <airlied@redhat.com>

* agp: Switch mask_memory() method to take address argument again, not pageDavid Woodhouse2009-08-031-1/+2
| | | | | | | | | | | In commit 07613ba2 ("agp: switch AGP to use page array instead of unsigned long array") we switched the mask_memory() method to take a 'struct page *' instead of an address. This is painful, because in some cases it has to be an IOMMU-mapped virtual bus address (in fact, shouldn't it _always_ be a dma_addr_t returned from pci_map_xxx(), and we just happen to get lucky most of the time?)

* agp: enable optimized agp_alloc_pages methodsRene Herman2008-08-221-0/+2
| | | | | | | | | | | | | | The pageattr-array patch that you currently have in tip/master only enables it for intel-agp, not the others. The attached enables it for all drivers currently directly using agp_generic_alloc_page() and agp_generic_destroy_page() (ocal driver is amd-k7-agp). The new agp_generic_alloc_pages() interface uses the also new pageattr array interface API. This makes all AGP drivers that up to now used generic_{alloc,destroy}_page() use it.

* fix historic ioremap() abuse in AGPArjan van dev Ven2008-02-191-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Several AGP drivers right now use ioremap_nocache() on kernel ram in order to turn a page of regular memory uncached. There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

* Fix "use after free" / "double free" bug in ati_create_gatt_pages / ↵Jesper Juhl2007-07-271-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ati_free_gatt_pages Hi, Coverity spotted a "use after free" bug in drivers/char/agp/ati-agp.c::ati_create_gatt_pages(). The same one that was in drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages() The problem is this: If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);" fails, then there's a loop in the function to free all entries allocated so far and break out of the allocation loop. That in itself is pretty sane, but then the (now freed) 'tables' is assigned to ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which causes ati_free_gatt_pages(); to be called at the end of the function. The problem with this is that ati_free_gatt_pages() will then loop 'ati_generic_private.num_tables' times and try to free each entry in tables[] - this is bad since tables has already been freed and furthermore it will call kfree(tables) at the end - a double free. This patch removes the freeing loop in ati_create_gatt_pages() and instead relies entirely on the call to ati_free_gatt_pages() to free everything we allocated in case of an error. It also sets ati_generic_private.num_tables to the actual number of entries allocated instead of just using the value passed in from the caller - this ensures that ati_free_gatt_pages() will only attempt to free stuff that was actually allocated. Note: I'm in no way intimate with this code and I have no way to actually test this patch (besides compile test it), so while I've tried to be careful in reading the code and make sure the patch does the right thing an ACK from someone who actually knows the code in-depth would be very much appreciated.

* [AGPGART] Allow drm-populated agp memory typesThomas Hellstrom2007-02-031-0/+1
| | | | | | | | | | | | | | | | | | | | 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/+2
|/ | | | | | | | | | | | | | | | | | | | | 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 Fraser2005-06-071-3/+3
| | | | | | | | | | | | | | | | | | | 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!
