* | | | | | | mm: add WasActive page flagBob Liu2016-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Zcache could be ineffective if the compressed memory pool is full with compressed inactive file pages and most of them will be never used again. So we pick up pages from active file list only, those pages would probably be accessed again. Compress them in memory can reduce the latency significantly compared with rereading from disk. When a file page is shrunk from active file list to inactive file list, PageActive flag is also cleared. So adding an extra WasActive page flag for zcache to know whether the file page was shrunk from the active list.

Added changes below to support dual platform driver for dual WiFi. Refactor the common api and data structure to avoid namespace collision compilation error. Refactor sdio and pcie bus specific kernel api and removed conditional compilation config flag. The platform driver at run time identifies the wlan bus type from the PHY device pointer passed by the wlan driver through vos api and cnss platform driver redirects the cnss api according the bus type. Remove conditional compilation flag from cnss common api and update cnss makefile for dual platform driver compilation with single config flag.

IOW the governor fails to see the net cpu demand of all related threads in a given window if the threads's execution were to be split across CPUs. That could result in sub-optimal frequency chosen in comparison to the ideal frequency at which the aggregate work (taken up by related threads) needs to be run. This patch aggregates cpu execution stats in a window for all related threads in a group. This helps present cpu busy time to governor as if all related threads were part of the same thread and thus help select the right frequency required by related threads. This aggregation is done per-cluster.

Add some checks to the io-pgtable-fast code to detect when an address that might be stale in the TLB is being re-used. This can be accomplished by writing a "stale TLB" flag value to the reserved bits of the PTE during unmap and then removing the flag value when the TLBs are invalidated (by sweeping the entire page table). That way, whenever we map we can know that there might be a stale TLB in the location being mapped into if it contains the "stale TLB" flag value.

This might happen in places where an IOMMU's clocks might not be known. A good example of this would be a test library that needs to be able to do TLB invalidation from atomic context. It would need to enable clocks up front (outside of atomic context) and leave them on for the duration of the test. Add some ops for enabling and disabling configuration clocks.

Therefore it's reasonable to get rid of current cpu_cycle_max_scale_factor and ask cycle counter read callback function to return scaled counter value when it's needed in such a case that cycle counter doesn't increase every cycle. Thus multiply NSEC_PER_SEC / HZ_PER_KHZ to CPU cycle counter delta as we calculate frequency in khz and remove cpu_cycle_max_scale_factor. This allows us to simplify frequency estimation and cycle counter API. Change-Id: Ie7a628d4bc77c9b6c769f6099ce8d75740262a14 Signed-off-by: Joonwoo Park <joonwoop@codeaurora.org>

PMCOBALT supports refreshed BTM peripheral register interface and the driver uses compatible property qpnp-adc-tm-hc to distinguish using the refreshed peripheral. The external client interface with the driver remains the same. Updates include handling the interrupt when the thresholds are crossed,programming the threholds and configuring the hardware based on the refreshed design. BTM peripheral needs the VADC_HC peripheral to compute the gain/offset that are used to reverse compute the threhold values to ADC code. Some of the reverse computation API's such as calculating thermistor thresholds require the gain and offset values before computing the ADC code to be programmed. This requires modification to the existing calibration API in the VADC_HC driver to calculate the reference calibration points and store these values for clients to use in the reverse computation Change-Id: I989cfa4f40e7f1671f04dfa9d4c3fe2ccbbc44ab Signed-off-by: Siddartha Mohanadoss <smohanad@codeaurora.org>

This leads to confusion of what charging enabled really means. POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED was introduced to indicate enabling the charge path, and in this case POWER_SUPPLY_PROP_CHARGING_ENABLED is used to indicate enabling the input path. Since these are similarly named it leads to even more confusion. In an attempt to fix this confusion we introduce a new power supply property POWER_SUPPLY_PROP_INPUT_SUSPEND which indicates suspending the input path of the power supply. POWER_SUPPLY_PROP_CHARGING_ENABLED takes its original definition of enabling the charge path. Then POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED will be retired from use.
