One of the simple imagine scenario about userspace's intelligence is that platform can manage tasks as forground and backgroud so it would be better to reclaim background's task pages for end-user's *responsibility* although it has frequent referenced pages. This patch adds new knob "reclaim under proc/<pid>/" so task manager can reclaim any target process anytime, anywhere. It could give another method to platform for using memory efficiently. It can avoid process killing for getting free memory, which was really terrible experience because I lost my best score of game I had ever after I switch the phone call while I enjoyed the game. Reclaim file-backed pages only. echo file > /proc/PID/reclaim Reclaim anonymous pages only. echo anon > /proc/PID/reclaim Reclaim all pages echo all > /proc/PID/reclaim Change-Id: Iabdb7bc2ef3dc4d94e3ea005fbe18f4cd06739ab Signed-off-by: Minchan Kim <minchan@kernel.org> Patch-mainline: linux-mm @ 9 May 2013 16:21:24 [vinmenon@codeaurora.org: trivial merge conflict fixes, and minor tweak of the commit msg] Signed-off-by: Vinayak Menon <vinmenon@codeaurora.org>

In the current solution, the host disables auto BKOPs or stops manual BKOPs in runtime suspend, regardless of the device need for BKOPs. This patch adds a check for device BKOPs status and defers suspend in case when BKOPs need.

| | * | | | | | | mmc: block: Error handling fixes and support of reset_allRitesh Harjani2016-05-31

Adds support to handle multiple cmdq software requests timeout. Currently we schedule error handling work for the first timedout request. We requeue all pending tasks, knock off all tasks from device queue and reset card and controller as part of this, then for all other software requests timeout, if it comes while executing error work, we return BLK_EH_NOT_HANDLED. This fixes BUG_ON in case of multiple requests timesout together. 2. Current code resets CQE, power cycle the card and requeue all the requests in case of any error. 3. mmc_blk_cmdq_err work takes care freeing up all resource allocation like clk and rpm hold, in case of reset_all. 4. Currently we were never clearing error CMDQ_STATE_ERR in case of any error. This patch takes care of this bug.

This acquires claim_host before calling mmc_power_restore. mmc_power_restore should be called with claim_host acquired, since this function is required from non-claim-host context in cmdq error handling.

This is to be mainly used in case of an error from cmdq_irq context. 2. Adds num_cq_slots & dcmd_cq_slot info to mmc_host structure. This can be useful info for mmc host structure like in case of handling of multiple error requests 3. Adds CMDQ_STATE_CQ_DISABLE for cmdq host. In case of an error if halt also fails, CQE error handling code will disable CQ. So block layer needs to know - to not pull any requests in such case.

Workaround was to wait for all the outstanding requests to finish up before queuing the flush request. Now detailed root cause analysis from vendor shows that original issue can happen only if DCMD command is sent to device too quickly (within less than 6 microseconds) after completion of previous small sector (less than 8 sectors) read operations. Hence with this change, we are fine tuning the previous workaround such that it would almost have no impact on the storage benchmark performance numbers.
