      [PATCH] AGP performance fixes · 88d51967
      Alan Hourihane 提交于
      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.

      [PATCH] agp: restore APBASE after setting APSIZE · b0825488
      Matthew Garrett 提交于
      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.

      [PATCH] AGP fix for Xen VMM · 07eee78e
      Keir Fraser 提交于
      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-rc2 · 1da177e4
      Linus Torvalds 提交于
      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!
