* ath9k: move ath9k_hw_setpower() to main.cLuis R. Rodriguez2009-10-07

* ath9k: avoid usage of ath9k_hw_setpower() on hw.cLuis R. Rodriguez2009-10-07
| | | | | | | | | | ath9k_hw_setpower() is a core driver helper with locking protection. Locking protection should be left to the driver core, not the hw code. Hardware code no longer contends for locking when it needs to wake up the chip or put it to sleep. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* ath9k: move ps helpers onto core driver when reseting tsfLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | | | When the TSF is reset power save state is disabled and then restored. The helpers to disable power save and restore it use a lock provided by the driver core. Move the callers of the helpers outside of the hw code. We reset the TSF when mac80211 tells us and on the beacon.c helper ath9k_hw_beaconinit() when it is made explicitly required. Add a helper on beacon.c which will deal with ps awake/restore if we need to reset the TSF upon ath9k_hw_beaconinit(). Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* ath9k: move driver core helpers to main.cLuis R. Rodriguez2009-10-07
| | | | | | | | | | | | | | | | | | Keep on btcoex.c only hardware access helpers, move the driver core specific code to main.c. To accomplish this we had to split ath_init_btcoex_info() into two parts, the driver core part -- ath_init_btcoex_timer() and the hw specific part -- ath9k_hw_init_btcoex_hw_info(). This highlights how ath_gen_timer is part of the driver core, not hw related, so stuff that into ath_btcoex struct. The ath9k_hw_btcoex_init() code is now put inline on ath_init_softc() through a switch to it easier to follow, since we did that we can now call ath_tx_get_qnum() from the main.c instead of btcoex.c Signed-off-by: Luis R.

The intent is to lower power consumption to ride-out transient electrical and thermal emergencies, rather than powering off the server. On platforms that can save more power/performance via P-states, the platform will first exhaust P-states before forcing idle. However, the relative benefit of P-states vs. idle states is platform dependent, and thus this driver need not know or care about it. This driver does not use the kernel's CPU hot-plug mechanism because after the transient emergency is over, the system must be returned to its normal state, and hotplug would permanently break both cpusets and binding. So to force idle, the driver creates a power saving thread. The scheduler will migrate the thread to the preferred CPU. The thread has max priority and has SCHED_RR policy, so it can occupy one CPU. To save power, the thread will invoke the deep C-state entry instructions. To avoid starvation, the thread will sleep 5% of the time time for every second (current RT scheduler has threshold to avoid starvation, but if other CPUs are idle, the CPU can borrow CPU timer from other, which makes the mechanism not work here) Vaidyanathan Srinivasan has proposed scheduler enhancements to allow injecting idle time into the system. This driver doesn't depend on those enhancements, but could cut over to them when they are available. Peter Z. does not favor upstreaming this driver until the those scheduler enhancements are in place. However, we favor upstreaming this driver now because it is useful now, and can be enhanced over time.

Moreover the _PRS acpi method says the irq is not shareable. In addition to this, in some cases, an additional write to the IO port has to be performed in order to properly decode the event received from the device. This generates another interrupt which may overlap with the previous one. In the future this is going to be important for properly decoding events.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having separate drivers for SPIC showed to be useless, only type3 has a slightly different behaviour than the others and there seem to be no real conflict between them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If i2c device probing fails, then there is no driver to dereference after calling i2c_new_device(). Stop assuming that probing will always succeed, to avoid NULL pointer dereferences. We have an easier access to the driver anyway.

| * | | | i2c: Hide probe errors caused by ACPI resource conflictsJean Delvare2009-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an ACPI resource conflict is detected, error messages are already printed by ACPI. There's no point in causing the driver core to print more error messages, so return one of the error codes for which no message is printed.
