2014-03-20cpufreq:LAB:ondemand: Enable usage of ONDEMAND specific methods at LAB governorLukasz Majewski1-1/+39
Two methods from ondemand, namely store_sampling_rate() and od_check_cpu() are now utilized in LAB governor. Moreover the od_cpu_dbs_info_s structure shall be regarded as a common one. Therefore in LAB only its declaration is necessary. Change-Id: I3408b2f8cfdb292cd69568c931da46d8f957099c Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>

2014-03-20cpufreq:LAB:core: Redesign of LAB code to work on top of ONDEMAND governorLukasz Majewski2-140/+231
The code for LAB has been redesigned to be able to work on top of Ondemand governor. Previous version of LAB - the one which used the polynomial approximation has been replaced with more readable approach. The LAB control approach is now read from device tree. User is allowed to specify following operations (based on load and number of idle CPUs): - Force a particular frequency - Explicitly enable boost for a specific kind of load - Use ondemand governor By using ondemand one can be sure that for non critical frequencies correct value will be chosen. LAB, which works on top of it, can clamp the freq (an thereof power management) or explicitly enable boost.

2014-03-20cpufreq:LAB:ondemand: REMOVE from LAB governor code duplicated at ondemandLukasz Majewski3-78/+17
LAB is very similar to ondemand governor in its structure. Both use the same code for: - governor init and exit - demand based switching timer code - governor specific ops In this way the LAB can be stacked on top of ondemand governor and hence it is possible to reuse its logic when needed.

2014-03-20usb: misc: usb3503: Remove 100ms sleep on reset, conform to data sheetJulius Werner1-4/+2
The usb3503 driver sleeps a flat 100ms when resetting the chip, with a comment about waiting for the reference clock. This seems to be a board-specific detail that should not hold up boot across all platforms. This patch reduces the sleep to the 4ms initialization delay that the chip itself actually requires (as per its data sheet). If certain boards require more time to set up the reference clock, they should change this through local patches or add a proper, configurable synchronization mechanism.

This patch restores correct value of cs_dbs_info pointer for conservative governor at CPUFREQ_GOV_STOP event.

2014-03-20cpufreq: ondemand: Change the calculation of target frequencyStratos Karafotis3-42/+8
The ondemand governor calculates load in terms of frequency and increases it only if load_freq is greater than up_threshold multiplied by the current or average frequency. This appears to produce oscillations of frequency between min and max because, for example, a relatively small load can easily saturate minimum frequency and lead the CPU to the max. Then, it will decrease back to the min due to small load_freq. Change the calculation method of load and target frequency on the basis of the following two observations: - Load computation should not depend on the current or average measured frequency. For example, absolute load of 80% at 100MHz is not necessarily equivalent to 8% at 1000MHz in the next sampling interval. - It should be possible to increase the target frequency to any value present in the frequency table proportional to the absolute load, rather than to the max only, so that: Target frequency = C * load where we take C = policy->cpuinfo.max_freq / 100. Tested on Intel i7-3770 CPU @ 3.40GHz and on Quad core 1500MHz Krait. Phoronix benchmark of Linux Kernel Compilation 3.1 test shows an increase ~1.5% in performance. cpufreq_stats (time_in_state) shows that middle frequencies are used more, with this patch. Highest and lowest frequencies were used less by ~9%. [rjw: We have run multiple other tests on kernels with this change applied and in the vast majority of cases it turns out that the resulting performance improvement also leads to reduced consumption of energy. The change is additionally justified by the overall simplification of the code in question.] Change-Id: I26399d5d61616ee9157baa7eb8b337bacab5b892 Signed-off-by: Stratos Karafotis <stratosk@semaphore.gr> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.

2014-03-20clk: propagate parent change up one levelTomasz Stanislawski1-0/+6
This patch adds support for propagation of setup of clock's parent one level up. This feature is helpful when a driver changes topology of its clocks using clk_set_parent(). The problem occurs when on one platform/SoC driver's clock is located at MUX output but on the other platform/SoC there is a gated proxy clock between the MUX and driver's clock. In such a case, driver's code has to be modified to use one clock for enabling and the other clock for setup of a parent. The code updates are avoided by propagating setup of a parent up one level. Additionally, this patch adds CLK_SET_PARENT_PARENT (sorry for naming) flag to inform clk-core that clk_set_parent() should be propagated.

2014-03-20usb: gadget: f_fs: add aio supportRobert Baldyga1-26/+239
This patch adds asynchronous I/O support for FunctionFS endpoint files. It adds ffs_epfile_aio_write() and ffs_epfile_aio_read() functions responsible for preparing AIO operations. It also modifies ffs_epfile_io() function, adding aio handling code. Instead of extending list of parameters of this function, there is new struct ffs_io_data which contains all information needed to perform I/O operation. Pointer to this struct replaces "buf" and "len" parameters of ffs_epfile_io() function. Allocated buffer is freed immediately only after sync operation, because in async IO it's freed in complete funcion. For each async operation an USB request is allocated, because it allows to have more than one request queued on single endpoint. According to changes in ffs_epfile_io() function, functions ffs_epfile_write() and ffs_epfile_read() are updated to use new API. For asynchronous I/O operations there is new request complete function named ffs_epfile_async_io_complete(), which completes AIO operation, and frees used memory.

2014-03-20usb: gadget: f_fs: add poll for endpoint 0Robert Baldyga1-0/+42
This patch adds poll function for file representing ep0. Ability of read from or write to ep0 file is related with actual state of ffs: - When desctiptors or strings are not written yet, POLLOUT flag is set. - If there is any event to read, POLLIN flag is set. - If setup request was read, POLLIN and POLLOUT flag is set, to allow send response (by performing I/O operation consistent with setup request direction) or set stall (by performing I/O operation opposite setup request direction).

2014-03-20usb: gadget: f_fs: fix setup request handlingRobert Baldyga2-2/+1
This patch fixes __ffs_ep0_queue_wait() function, which now returns number of bytes transferred in USB request or error code in case of failure. This is needed by ffs_ep0_read() function, when read data is copied to userspace. It also cleans up code by removing usused variable ep0req_status.

2014-03-20usb: gadget: functionfs: replace FFS_SETUP_STATUS with an inline functionMichal Nazarewicz2-10/+19
The FFS_SETUP_STATUS macro could be trivialy replaced with an static inline function but more importantly its name was tad confusing. The name suggested it was a simple accessor macro but it actually did change the state of the ffs_data structure perfomring a FFS_SETUP_CANCELLED -> FFS_NO_SETUP transition. The name of the function -- ffs_setup_state_clear_cancelled -- should better describe what the function actually does.
