2018-10-23libpagemap: pm_map: skip pages that are neither present nor swapped.Sandeep Patil
The pm_map_workingset() code needlessly iterates through all the pages in the map regardless of whether they are actually present or not. Fix that by skipping the page if its not swapped AND not present.

2018-08-22libpagemap: procmem: Add option to sort by USS.Sandeep Patil
In same case, especially working set, USS may be much more actionable for a process than PSS. Add option to sort by USS in all cases for the same.

2018-08-22libpagemap: procmem: Reset working set everytime if page_idle is used.Sandeep Patil
Idle page tracking works a bit differently than that of clear_refs. A write of 1 to page_idle/bitmap tell the kernel to determine if the page is "idle" and is not accessed *anytime* in the past. This way, we end up catching any new allocations that may have been done since the last time working set was reset too. Bug: 111694435 Test: procmem -h -W 1 && procmem -h -w 1 Test: procmem -h -i -W 1 Test: procmem -h -i -w 1 Test: procmem -h -i -w <pid>; alloc memory in <pid>; procmem -h -i -w <pid> Observe that newly allocated and set memory is no accounted in the working set.

2018-08-22libpagemap: Add APIs to mark and read idle pages of a process.Sandeep Patil
pm_kernel_init_page_idle() - Initialize idle page tracking. pm_kernel_has_page_idle() - Returns 1 if idle page tracking has been successfully initialized. pm_kernel_get_page_idle() - Gets the idle status of the page frame. pm_kernel_mark_page_idle() - Marks one or many page frames idle. pm_kernel_page_is_accessed() - Returns 1 if page is accessed. pm_map_mark_idle() - Marks mapped pages from a pagemap idle. Added '-i' usage flag to procmem that tells procmem to use idle page tracking. The flag is ignored in the absense of '-w' or '-W' options. Bug: 111694435 Test: procmem -i -h 1 Test: procmem -h -W 1 && procmem -h -w 1 Test: procmem -h -i -W 1 && procmem -h -i -w 1 Change-Id: Ib9cb679427798426c9477500552e9aa83a40fd48 Signed-off-by: Sandeep Patil <sspatil@google.com>

2018-08-16libpagemap: make pm_kernel_* APIs consistently return negative errors.Sandeep Patil
pm_kernel_* APIs return errnos as error values, which works because almost all callers check if the return value is 'true' or 'false'. Most other APIs in libpagemap return negative errors however. Fix pm_kernel_* APIs to be consistent with other library functions.

2017-09-07Mark the module as VNDK or VNDK-SP in Android.bpJustin Yun
As a VNDK/VNDK-SP module, Android.bp must have 'vndk' tag as well as 'vendor_available: true'. For a VNDK module, the 'vndk' tag has 'enabled: true'. It will be installed system/lib(64)/vndk as a vendor variant. For a VNDK-SP module, the 'vndk' tag has 'support_system_process: true' as well as 'enabled: true'. It will be installed system/lib(64)/vndk-sp as a vendor variant.

2015-11-30procrank: add proportional swap accountingThierry Strudel
Shared pages are reported in each of the sharing process swapped pages. Compute a proportional swap usage to get a meaningful value of what each process has in swap. Report also process unique pages swapped out. In case ZRAM is used compute the compression ration and report the actual RAM use of the swapped pages.

2014-05-14libpagemap: handle zero length memory regionsColin Cross
/proc/pid/maps may report a zero-length memory region for a 4kB PROT_GROWSDOWN region because it subtracts 4kB for the guard page. Return 0 instead of -1 when this occurs, and set range_out to NULL and len to 0. All existing callers of pm_process_pagemap_range will not dereference range_out if len is 0.
