5
6OMAP2 does not use OPP tables at the moment for DVFS. Currently,
7we depend on opp table initialization to give us the freq_table,
8which makes sense for OMAP3+. for OMAP2, we should be using
9clk_init_cpufreq_table - so if the opp based frequency table
10initilization fails, fall back to clk_init_cpufreq_table to give
11us the table.

5
6Use cpufreq_frequency_table_target for finding the proper target
7instead of seeing if the frequency requested is divisible alone.
8if we have a frequency table, we should restrict ourselves to
9selecting the "approved" frequencies alone and only in the case
10where the frequency table is not available should we attempt at
11closest roundable clock frequency.

6Since we have two cpus the cpuinit call for cpu1 causes
7freq_table of cpu0 to be overwritten. instead, we maintain
8a counter to keep track of cpus who use the cpufreq table
9allocate it once(one freq table for all CPUs) and free them
10once the last user is done with it.

6Two new functions for getting the next higher and next lower frequencies
7in the cpufreq table, based upon a frequency supplied in kHz.
8
9This is useful for cpufreq governors that do not target frequencies
10based upon a percentage or a pre-determined value, but instead access
11the cpufreq table directly.

4Subject: [PATCH 53/59] cpufreq: introduce hotplug governor
5
6The "hotplug" governor scales CPU frequency based on load, similar to
7"ondemand". It scales up to the highest frequency when "up_threshold"
8is crossed and scales down one frequency at a time when "down_threshold"
9is crossed. Unlike those governors, target frequencies are determined
10by directly accessing the CPUfreq frequency table, instead of taking
11some percentage of maximum available frequency.
12
13The key difference in the "hotplug" governor is that it will disable
14auxillary CPUs when the system is very idle, and enable them again once
15the system becomes busy. This is achieved by averaging load over
16multiple sampling periods; if CPUs were online or offlined based on a
17single sampling period then thrashing will occur.
18
19Sysfs entries exist for "hotplug_in_sampling_periods" and for
20"hotplug_out_sampling_periods" which determine how many consecutive
21periods get averaged to determine if auxillery CPUs should be onlined or
22offlined. Defaults are 5 periods and 20 periods respectively.
23Otherwise the standard sysfs entries you might find for "ondemand" and
24"conservative" governors are there.
25
26To use this governor it is assumed that your CPUfreq driver has
27populated the CPUfreq table, CONFIG_NO_HZ is enabled and
28CONFIG_HOTPLUG_CPU is enabled.
29
30Changes in V2:
31 Corrected default sampling periods
32 Optimized load history array resizing
33 Maintain load history when resizing array
34 Add locking to dbs_check_cpu
35 Switch from enable_nonboot_cpus to cpu_up
36 Switch from disable_nonboot_cpus to down_cpu
37 Fix some printks
38 Coding style around for-loops

61+2.6 Hotplug
62+-----------
63+
64+The CPUfreq governor "hotplug" operates similary to "ondemand" and
65+"conservative". It's decisions are based primarily on CPU load. Like
66+"ondemand" the "hotplug" governor will ramp up to the highest frequency
67+once the run-time tunable "up_threshold" parameter is crossed. Like
68+"conservative", the "hotplug" governor exports a "down_threshold"
69+parameter that is also tunable at run-time. When the "down_threshold"
70+is crossed the CPU transitions to the next lowest frequency in the
71+CPUfreq frequency table instead of decrementing the frequency based on a
72+percentage of maximum load.
73+
74+The main reason "hotplug" governor exists is for architectures requiring
75+that only the master CPU be online in order to hit low-power states
76+(C-states). OMAP4 is one such example of this. The "hotplug" governor
77+is also helpful in reducing thermal output in devices with tight thermal
78+constraints.
79+
80+Auxillary CPUs are onlined/offline based on CPU load, but the decision
81+to do so is made after averaging several sampling windows. This is to
82+reduce CPU hotplug "thrashing", which can be caused by normal system
83+entropy and leads to lots of spurious plug-in and plug-out transitions.
84+The number of sampling periods averaged together is tunable via the
85+"hotplug_in_sampling_periods" and "hotplug_out_sampling_periods"
86+run-time tunable parameters.

34PM: Prevent direct cpufreq scaling during initialization
35
36It is seen that the OMAP specific cpufreq initialization code tries to
37scale the MPU frequency to the highest possible without taking care of
38the voltage level. On power on reset the power IC does not provide the
39necessary voltage for the highest available MPU frequency (that would
40satisfy all Si families). This potentially is an window of opportunity
41for things to go wrong.

54With this patch, omap opp layer now has its compilation flags
55bound to CONFIG_CPU_FREQ. Also its code has been removed from pm34xx.c.
56
57A new file has been created to contain cpu freq code related to
58OMAP3: cpufreq34xx.c

71
72For board files which choose to override the defaults, the existing
73mechanism will work, for boards that would like to work with defaults,
74allow init_common_hw to call init_opp_table to initialize if not
75already initialized. this will allow all omap boards which have opp
76tables predefined for a silicon to use the same.

100
101Make opp3xx data which is registered with the opp layer
102dependent purely on CONFIG_PM as opp layer and pm.c users
103are CONFIG_PM dependent not cpufreq dependent.
104so we rename the data definition to opp3xxx_data.c (inline with what
105we have for omap2), also move the build definition to be under
106the existing CONFIG_PM build instead of CPUFREQ.

4Subject: [PATCH 47/59] OMAP: PM: CPUFREQ: Fix conditional compilation
5
6Fix conditional compilation. A conditional expresiion
7should follow "#elif", in this case #elif clause should
8check whether CONFIG_ARCH_OMAP3 is defined or not
9(ie. defined(CONFIG_ARCH_OMAP3)) rather than checking for
10the value of the macro.

4Subject: [PATCH 49/59] OMAP: cpufreq: Split OMAP1 and OMAP2PLUS CPUfreq drivers.
5
6This patch is an attempt to cleanup the #ifdeferry in the
7omap CPUfreq drivers.
8
9The split betwenn OMAP1 and OMAP2PLUS is logical because
10 - OMAP1 doesn't support opp layer.
11 - OMAP1 build is seperate from omap2plus.

4Subject: [PATCH 50/59] OMAP2PLUS: cpufreq: Add SMP support to cater OMAP4430
5
6On OMAP SMP configuartion, both processors share the voltage
7and clock. So both CPUs needs to be scaled together and hence
8needs software co-ordination.

6Fix this typo as there is no dpll_mpu_ck for OMAP3 and code flow is clearly
7trying to set mpu_clk for OMAP4 for which this dpll_mpu_ck is available.

4Subject: [PATCH 39/59] OMAP3 cpuidle: remove useless SDP specific timings
5
6The cpuidle states settings can be overriden by some board-
7specific settings, by calling omap3_pm_init_cpuidle.
8Remove the 3430SDP specific states settings registration
9since the figures are identical to the default ones (in cpuidle34xx.c).

4Subject: [PATCH 40/59] OMAP3+: SR: make notify independent of class
5
6Interrupt notification mechanism of SmartReflex can be used by the
7choice of implementation of the class driver. For example, Class 2 and
8Class 1.5 of SmartReflex can both use the interrupt notification to
9identify the transition of voltage or other events.
10
11Hence, the actual class does not matter for notifier. Let the class
12driver's handling decide how it should be used. SmartReflex driver
13should provide just the primitives.

4Subject: [PATCH 41/59] OMAP3+: SR: disable interrupt by default
5
6We will enable and disable interrupt on a need basis in the class
7driver. We need to keep the IRQ disabled by default else the
8forceupdate or vcbypass events could trigger events that we don't
9need/expect to handle.
10
11This is a preparation for SmartReflex AVS class drivers such as
12class 2 and class 1.5 which would need to use interrupts. Existing
13SmartReflex AVS class 3 driver does not require to use interrupts
14and is not impacted by this change.
