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. Bug: 111694435 Test: procmem -h -u 1 Test: procmem -h -i -u -w 1 Change-Id: Ifb9c4bd2ff18bb73d82c492cb1862a065ed630b4 Signed-off-by: Sandeep Patil <sspatil@google.com>
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.

2018-08-15Convert mkuserimg_mke2fs.sh to pythonTianjie Xu
The mkuserimg_mke2fs.sh was a shell script, which expects all the arguments in order. This cl changes the script to python which leverages python's argumentparser and unittest modules. The script usage is unchanged; and this tool will be packed into the otatools.zip in the follow up cls. Then we'll change the caller site gradually; and remove the old shell script after that.

Switch inferno.py to use --pid option in app_profiler.py. Because the previous way of converting pid to program name doesn't work well on system_server process. Add tests in test.py.
