The vmalloc_32 function together with the memset to clear
the new pages are replaced with a vmalloc_user.
A pre-2.6.18 compat vmalloc_user is added.
Please replace any breakage on machines with > 1GB of memory.

TTM pages were not cleared when allocated and handed to user space.
Sensitive information may leak.

Shared memory areas were not cleared when they are allocated and
handed to user space. Sensitive information may leak.

Avoid calling reclaim_buffers_locked if we don't have a
hardware lock.
Improve reclaim_buffers_locked deadlock error formatting.

Bye bye 2.4 you served us well..

Make sure the callers do a pgprot_noncached() on
vma->vm_page_prot.

Some drivers are returning OOM when it is not in response to a memory
shortage.

This reverts cc22cd8bde39f3e4be8ca9f726a773b0270ebdbc commit.
I put this patch incorrectly in .. will fix now

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.
Tested (compilation only) to make sure the files are compiling without
any warning/error due to new changes

I need the following patch to fix compilation of
latest drm/linux-core on my ppc64 machine.
/home/mb/develop/git/drm/linux-core/savage_bci.c: In function ‘savage_driver_firstopen’:
/home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: ‘DRM_MTRR_WC’ undeclared (first use in this function)
/home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: (Each undeclared identifier is reported only once
/home/mb/develop/git/drm/linux-core/savage_bci.c:587: error: for each function it appears in.)
/home/mb/develop/git/drm/linux-core/savage_bci.c: In function ‘savage_driver_lastclose’:
/home/mb/develop/git/drm/linux-core/savage_bci.c:664: error: ‘DRM_MTRR_WC’ undeclared (first use in this function)
I looked at in-kernel drmP.h and it actually
has the same fix in it.

since the support for memory caches has gone from 2.6.20.
|
|
The current version didn't build on BSD, where the new functionality isn't used
yet anyway. Whoever changes that will hopefully be able to make the OSes share
this file as well.

Build fixes for powerpc.

This will come in very handy for tiled buffers on intel hardware.
Also add some padding to interface structures to allow future binary backwards
compatible changes.
|
|
|
|
This makes an allocated block actually align itself and returns any
wasted space to the manager.
Also add some functions to grow and shrink the managed area.
This will be used in the future to manage the buffer object swap cache.

otherwise data will be missing, which becomes apparent when the kernel evicts
batch buffers which are likely to be written into in the evicted state,
and then rebound to the AGP aperture.
This means we cannot rely on the AGP module to flush the
cache for us.

driver we're on.
Avoid global cache flushes before inserting pages.
In general, they are never mapped, and not accessed through the kernel map, so
a cache flush should not be necessary. The exception is pages that are bound
cached. We might need a cache flush for those.
|
|
that is now handled by the memory accounting.
|
|
|
|
Use byte unit for /proc printout of memory usage for small sizes to be
able to detect memory allocation bugs more easily.

The mm_lock function is used when leaving vt. It evicts _all_ buffers.
Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to
get the same offset when / if they are rebound.
