ashmem: Anonymous shared memory subsystem

2011-12-21T21:38:28+00:00

The anonymous shared memory (ashmem) subsystem provides a
Unix-y,file-based shared memory interface to user-space. It
works like anonymous memory (e.g. mmapping fd=0) except if
you share the file descriptor via the usual means, you will
share the mapping. The shared memory can be accessed via both
mmap or file I/O. The backing store is a simple shmem file.

Additionally, ashmem introduces the concept of page pinning.
Pinned pages (the default) behave like any anonymous memory.
Unpinned pages are available to the kernel for eviction during
VM pressure. When repinning the pages, the return value
instructs user-space as to any eviction. In this manner,
user-space processes may implement caching and similar
resource management that efficiently integrates with kernel
memory management.

ashmem: Don't install fault handler for private mmaps.

Ashmem is used to create named private heaps. If this heap is backed
by a tmpfs file it will allocate two pages for every page touched.
In 2.6.27, the extra page would later be freed, but 2.6.29 does not
scan anonymous pages when running without swap so the memory is not
freed while the file is referenced. This change changes the behavior
of private ashmem mmaps to match /dev/zero instead tmpfs.

ashmem: don't require a page aligned size

This makes ashmem more similar to shmem and mmap, by
not requiring the specified size to be page aligned,
instead rounding it internally as needed.

[jstultz: Improved commit subject and included patch description
from rlove. Also moved ashmem files to staging dir, and reworked
code to avoid touching mm/shmem.c while we're in staging.]

staging: android: add pmem driver

2011-12-16T22:08:17+00:00

This adds the Android pmem driver to the staging tree.

[At this point in time, it is dependent on the ARM platform, due to some
build issues that require it. - gregkh]

staging: android: switch: switch class and GPIO drivers.

2011-12-16T21:38:14+00:00

This adds the Android switch driver code to the staging tree.

[Note, this code was located in drivers/switch/ in the Android kernel
releases, but as that api wasn't generally accepted, and the interface
is working toward changing to the newly proposed extcon inteface, this
driver was placed here until the extcon code is merged into mainline and
the Android userspace code is converted over to using it. - gregkh]

Revert "Staging: android: mark subsystem as broken"

2011-11-30T11:32:24+00:00

This reverts commit 2cdf99ce2b9418c9d7c5f907195cfac421375520.

It now builds, so this can be reverted.

Revert "Staging: android: delete android drivers"

2011-11-30T11:18:14+00:00

This reverts commit b0a0ccfad85b3657fe999805df65f5cfe634ab8a.

Turns out I was wrong, we want these in the tree.

Note, I've disabled the drivers from the build at the moment, so other
patches can be applied to fix some build issues due to internal api
changes since the code was removed from the tree.

Staging: android: delete android drivers

2009-12-11T20:23:21+00:00

These drivers are no longer being developed and the original authors
seem to have abandonded them and hence, do not want them in the mainline
kernel tree.

So sad :(

Staging: android: mark subsystem as broken

2009-10-30T21:47:44+00:00

It's causing lots of build errors, so just mark it as broken.  It is
scheduled to be removed in 2.6.33 anyway.

specific Android drivers even if you say N to CONFIG_ANDROID
