ashmem: Anonymous shared memory subsystem

2011-12-21T21:38:28Z

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. Signed-off-by: Robert Love 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. Signed-off-by: Arve Hjønnevåg ashmem: Add common prefix to name reported in /proc/pid/maps Signed-off-by: Arve Hjønnevåg 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. Signed-off-by: Marco Nelissen [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.] CC: Brian Swetland CC: Colin Cross CC: Arve Hjønnevåg CC: Dima Zavin CC: Robert Love Signed-off-by: John Stultz Signed-off-by: Greg Kroah-Hartman

staging: android: add pmem driver

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] Signed-off-by: Rebecca Schultz Signed-off-by: Rebecca Schultz Zavin Signed-off-by: Dima Zavin Signed-off-by: Jamie Gennis Cc: Brian Swetland Cc: Arve Hjønnevåg Cc: Colin Cross Signed-off-by: Greg Kroah-Hartman

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

2011-12-16T21:38:14Z

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] Signed-off-by: Arve Hjønnevåg Signed-off-by: Mike Lockwood Cc: MyungJoo Ham Cc: Kyungmin Park Cc: Donggeun Kim Cc: Arnd Bergmann Cc: MyungJoo Ham Cc: Linus Walleij Cc: Dmitry Torokhov Cc: NeilBrown Cc: Morten CHRISTIANSEN Cc: Mark Brown Cc: John Stultz Signed-off-by: Greg Kroah-Hartman

Revert "Staging: android: delete android drivers"

2011-11-30T11:18:14Z

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.

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 :( Cc: Brian Swetland Signed-off-by: Greg Kroah-Hartman
