      drm/ttm: Allocate the page pool manager in the heap. · 5870a4d9
      Francisco Jerez authored
      
      
      Repeated ttm_page_alloc_init/fini fails noisily because the pool
      manager kobj isn't zeroed out between uses (we could do just that but
      statically allocated kobjects are generally considered a bad thing).
      Move it to kzalloc'ed memory.
      
      Note that this patch drops the refcounting behavior of the pool
      allocator init/fini functions: it would have led to a race condition
      in its current form, and anyway it was never exploited.
      
      This fixes a regression with reloading kms modules at runtime, since
      page allocator was introduced.

      drm/ttm: remove io_ field from TTM V6 · 0c321c79
      Jerome Glisse authored
      
      
      All TTM driver have been converted to new io_mem_reserve/free
      interface which allow driver to choose and return proper io
      base, offset to core TTM for ioremapping if necessary. This
      patch remove what is now deadcode.
      
      V2 adapt to match with change in first patch of the patchset
      V3 update after io_mem_reserve/io_mem_free callback balancing
      V4 adjust to minor cleanup
      V5 remove the needs ioremap flag
      V6 keep the ioremapping facility in TTM
      
      [airlied- squashed driver removals in here also]

      drm/ttm: ttm_fault callback to allow driver to handle bo placement V6 · 82c5da6b
      Jerome Glisse authored
      
      
      On fault the driver is given the opportunity to perform any operation
      it sees fit in order to place the buffer into a CPU visible area of
      memory. This patch doesn't break TTM users, nouveau, vmwgfx and radeon
      should keep working properly. Future patch will take advantage of this
      infrastructure and remove the old path from TTM once driver are
      converted.
      
      V2 return VM_FAULT_NOPAGE if callback return -EBUSY or -ERESTARTSYS
      V3 balance io_mem_reserve and io_mem_free call, fault_reserve_notify
         is responsible to perform any necessary task for mapping to succeed
      V4 minor cleanup, atomic_t -> bool as member is protected by reserve
         mecanism from concurent access
      V5 the callback is now responsible for iomapping the bo and providing
         a virtual address this simplify TTM and will allow to get rid of
         TTM_MEMTYPE_FLAG_NEEDS_IOREMAP
      V6 use the bus addr data to decide to ioremap or this isn't needed
         but we don't necesarily need to ioremap in the callback but still
         allow driver to use static mapping

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.
