| * [CPUFREQ] CPUfreq ondemand: update sampling rate without waiting for next ↵MyungJoo Ham2012-03-011-1/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sampling When a new sampling rate is shorter than the current one, (e.g., 1 sec --> 10 ms) regardless how short the new one is, the current ondemand mechanism wait for the previously set timer to be expired. For example, if the user has just expressed that the sampling rate should be 10 ms from now and the previous was 1000 ms, the new rate may become effective 999 ms later, which could be not acceptable for the user if the user has intended to speed up sampling because the system is expected to react to CPU load fluctuation quickly from __now__. In order to address this issue, we need to cancel the previously set timer (schedule_delayed_work) and reset the timer if resetting timer is expected to trigger the delayed_work ealier.

| * [CPUFREQ] Add S3C2416/S3C2450 cpufreq driverHeiko Stübner2012-03-013-0/+565
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The S3C2416/S3C2450 SoCs support two sources for the armclk. The first source is the so called armdiv which divides the msysclk down to provide necessary cpu rates. In this mode the core voltage must be always at 1.3V. The frequency from the armdiv is not allowed to be lower than the hclk frequency. In the second mode the armclk can be sourced directly from the hclk in the so called "dynamic voltags scaling" (dvs) mode. Here the armdiv isn't used at all. Also in this mode the core voltage may be lowered. Existing hardware and tests with it suggest 1.0V as sufficient. When changing the clock source to the armdiv from the hclk, the SoC shows stability issues if the new frequency is higher than the current hclk frequency. Hence the driver always forces the armdiv to the hclk frequency before the source change and lets the cpufreq issue another set_target call for higher frequencies. To mark the hclk frequency as lower as the corresponding armdiv frequency it is set 1MHz below the real frequency. This lets the cpufreq framework change between 133MHz based on hclk and 133MHz based on armdiv at will.

This will prevent adding a latency, although very minor, for _every_ request. Moreover the runtime_get_sync is now also used in set_ios and suspend since the runtime resourses are needed here as well.

We remove it and use a generic approach instead. A new ios_handler is added, the purpose of which e.g. can be to control GPIO pins to a levelshifter. Previously the vdd_handler was also used for making additional changes to the power register bits. This option is superfluous and is therefore removed. Adaptaptions from the old vdd_handler to the new ios_handler is done for mach-ux500 board, which was the only one using the vdd_handler. This patch is based upon a patch from Sebastian Rasmussen.

By some reason the USB driver allocates buffers which requires a scattergather list to contain a lot more than 16 elements to get optimal performance. This change sets the maximum elements to 128. Tests with large reads and large writes (100 MiB) show that the throughput increase is significant for write (10% for this test) but not for read. Tests are run on a Linux host with ext4 FS on the gadget mass storage device. The sg-len still exceeds 16 for the read tests but the performance gain is low or nothing.
