2011-07-10I2C: OMAP2+: add correct functionality flags to all omap2plus i2c dev_attrAndy Green

2011-07-10I2C: OMAP2+: Tag all OMAP2+ hwmod defintions with I2C IP revisionAndy Green
Since we cannot trust (or even reliably find) the OMAP I2C peripheral unit's own revision register, we must inform the OMAP i2c driver of which IP version it is running on. We do this by tagging the omap_hwmod_class for i2c on all the OMAP2+ platform / cpu specific hwmod init and passing it up to the driver (next patches).

2011-07-10I2C: OMAP2+: increase omap_i2c_dev_attr flags from u8 to u32Andy Green
As part of removing cpu_...() from the OMAP I2C driver, we need to convert the CPU tests into functionality flags that are set by hwmod class in the same way the IP revision is. More flags are needed than will fit in the existing u8 flags member of omap_i2c_dev_attr. These flags can refer to options inside the IP block but they are most needed for information about cpu implementation specific options that are not part of the IP block itself. For example, how the CPU data bus is wired to the IP block databus differs between OMAP cpus and affects how you must shift the address in the IP block, but is not a feature of the IP block itself.

2011-07-10I2C: OMAP2+: Set hwmod flags to only allow 16-bit accesses to i2cAndy Green
Peter Maydell noticed when running under QEMU he was getting errors reporting 32-bit access to I2C peripheral unit registers that are documented to be 8 or 16-bit only[1][2] The I2C driver is blameless as it wraps its accesses in a function using __raw_writew and __raw_readw, it turned out it is the hwmod stuff. However the hwmod code already has a flag to force a perhipheral unit to only be accessed using 16-bit operations. This patch applies the 16-bit only flag to the 2430, OMAP3xxx and OMAP44xx hwmod structs. 2420 was already correctly marked up as 16-bit. The 2430 change will need testing by TI as arranged in the comments to the previous patch version. When the 16-bit flag is or-ed with other flags, it is placed first as requested in comments.

2011-07-10OMAP4: hwmod data: Change DSS main_clk schemeTomi Valkeinen
Currently using pm_runtime with DSS requires the DSS driver to enable the DSS functional clock before calling pm_runtime_get(). That makes it impossible to use pm_runtime in DSS as it is meant to be used, with pm_runtime callbacks. This patch changes the hwmod database for OMAP4 so that enabling the hwmod via pm_runtime will also enable the DSS functional clock, allowing us to use pm_runtime properly in DSS driver. The DSS HWMOD side is not really correct, not before nor after this patch, and getting DSS to retention will probably not work currently. However, it is not supported in the mainline kernel anyway, so this won't break anything. So this patch allows us to write the pm_runtime adaptation for the DSS driver the way it should be done, and the HWMOD/PM side can be fixed later.

2011-07-10ARM: mach-shmobile: sh7372 A3RV requires A4LCMagnus Damm
Add a power domain workaround for the VPU and A3RV on sh7372. The sh7372 data sheet mentions that the VPU is located in the A3RV power domain. The A3RV power domain is not related to A4LC in any way, but testing shows that unless A3RV _and_ A4LC are powered on the VPU test program will bomb out. This issue may be caused by a more or less undocumented dependency on the MERAM block that happens to be located in A4LC. So now we know that the out-of-reset requirement of the VPU is that the MERAM is powered on. This patch adds a workaround for A3RV to make sure A4LC is powered on - this so we can use the VPU even though the LCDCs are in blanking state and A4LC is supposed to be off.

2011-07-09writeback: scale IO chunk size up to half device bandwidthWu Fengguang
Originally, MAX_WRITEBACK_PAGES was hard-coded to 1024 because of a concern of not holding I_SYNC for too long. (At least, that was the comment previously.) This doesn't make sense now because the only time we wait for I_SYNC is if we are calling sync or fsync, and in that case we need to write out all of the data anyway. Previously there may have been other code paths that waited on I_SYNC, but not any more. -- Theodore Ts'o So remove the MAX_WRITEBACK_PAGES constraint. The writeback pages will adapt to as large as the storage device can write within 500ms. XFS is observed to do IO completions in a batch, and the batch size is equal to the write chunk size. To avoid dirty pages to suddenly drop out of balance_dirty_pages()'s dirty control scope and create large fluctuations, the chunk size is also limited to half the control scope. The balance_dirty_pages() control scrope is [(background_thresh + dirty_thresh) / 2, dirty_thresh] which is by default [15%, 20%] of global dirty pages, whose range size is dirty_thresh / DIRTY_FULL_SCOPE. The adpative write chunk size will be rounded to the nearest 4MB boundary. http://bugzilla.kernel.org/show_bug.cgi?id=13930 CC: Theodore Ts'o <tytso@mit.edu> CC: Dave Chinner <david@fromorbit.com> CC: Chris Mason <chris.mason@oracle.com> CC: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Wu Fengguang <fengguang.wu@intel.com>
2011-07-09writeback: trace global_dirty_stateWu Fengguang

2011-07-09writeback: introduce max-pause and pass-good dirty limitsWu Fengguang
The max-pause limit helps to keep the sleep time inside balance_dirty_pages() within MAX_PAUSE=200ms. The 200ms max sleep means per task rate limit of 8pages/200ms=160KB/s when dirty exceeded, which normally is enough to stop dirtiers from continue pushing the dirty pages high, unless there are a sufficient large number of slow dirtiers (eg. 500 tasks doing 160KB/s will still sum up to 80MB/s, exceeding the write bandwidth of a slow disk and hence accumulating more and more dirty pages). The pass-good limit helps to let go of the good bdi's in the presence of a blocked bdi (ie. NFS server not responding) or slow USB disk which for some reason build up a large number of initial dirty pages that refuse to go away anytime soon. For example, given two bdi's A and B and the initial state bdi_thresh_A = dirty_thresh / 2 bdi_thresh_B = dirty_thresh / 2 bdi_dirty_A = dirty_thresh / 2 bdi_dirty_B = dirty_thresh / 2 Then A get blocked, after a dozen seconds bdi_thresh_A = 0 bdi_thresh_B = dirty_thresh bdi_dirty_A = dirty_thresh / 2 bdi_dirty_B = dirty_thresh / 2 The (bdi_dirty_B < bdi_thresh_B) test is now useless and the dirty pages will be effectively throttled by condition (nr_dirty < dirty_thresh). This has two problems: (1) we lose the protections for light dirtiers (2) balance_dirty_pages() effectively becomes IO-less because the (bdi_nr_reclaimable > bdi_thresh) test won't be true. This is good for IO, but balance_dirty_pages() loses an important way to break out of the loop which leads to more spread out throttle delays. DIRTY_PASSGOOD_AREA can eliminate the above issues. The only problem is, DIRTY_PASSGOOD_AREA needs to be defined as 2 to fully cover the above example while this patch uses the more conservative value 8 so as not to surprise people with too many dirty pages than expected. The max-pause limit won't noticeably impact the speed dirty pages are knocked down when there is a sudden drop of global/bdi dirty thresholds. Because the heavy dirties will be throttled below 160KB/s which is slow enough. It does help to avoid long dirty throttle delays and especially will make light dirtiers more responsive.

2011-07-09writeback: introduce smoothed global dirty limitWu Fengguang
The start of a heavy weight application (ie. KVM) may instantly knock down determine_dirtyable_memory() if the swap is not enabled or full. global_dirty_limits() and bdi_dirty_limit() will in turn get global/bdi dirty thresholds that are _much_ lower than the global/bdi dirty pages. balance_dirty_pages() will then heavily throttle all dirtiers including the light ones, until the dirty pages drop below the new dirty thresholds. During this _deep_ dirty-exceeded state, the system may appear rather unresponsive to the users. About "deep" dirty-exceeded: task_dirty_limit() assigns 1/8 lower dirty threshold to heavy dirtiers than light ones, and the dirty pages will be throttled around the heavy dirtiers' dirty threshold and reasonably below the light dirtiers' dirty threshold. In this state, only the heavy dirtiers will be throttled and the dirty pages are carefully controlled to not exceed the light dirtiers' dirty threshold. However if the threshold itself suddenly drops below the number of dirty pages, the light dirtiers will get heavily throttled. So introduce global_dirty_limit for tracking the global dirty threshold with policies - follow downwards slowly - follow up in one shot global_dirty_limit can effectively mask out the impact of sudden drop of dirtyable memory. It will be used in the next patch for two new type of dirty limits. Note that the new dirty limits are not going to avoid throttling the light dirtiers, but could limit their sleep time to 200ms.

2011-07-09writeback: bdi write bandwidth estimationWu Fengguang
The estimation value will start from 100MB/s and adapt to the real bandwidth in seconds. It tries to update the bandwidth only when disk is fully utilized. Any inactive period of more than one second will be skipped. The estimated bandwidth will be reflecting how fast the device can writeout when _fully utilized_, and won't drop to 0 when it goes idle. The value will remain constant at disk idle time. At busy write time, if not considering fluctuations, it will also remain high unless be knocked down by possible concurrent reads that compete for the disk time and bandwidth with async writes. The estimation is not done purely in the flusher because there is no guarantee for write_cache_pages() to return timely to update bandwidth. The bdi->avg_write_bandwidth smoothing is very effective for filtering out sudden spikes, however may be a little biased in long term. The overheads are low because the bdi bandwidth update only occurs at 200ms intervals. The 200ms update interval is suitable, because it's not possible to get the real bandwidth for the instance at all, due to large fluctuations. The NFS commits can be as large as seconds worth of data. One XFS completion may be as large as half second worth of data if we are going to increase the write chunk to half second worth of data. In ext4, fluctuations with time period of around 5 seconds is observed. And there is another pattern of irregular periods of up to 20 seconds on SSD tests. That's why we are not only doing the estimation at 200ms intervals, but also averaging them over a period of 3 seconds and then go further to do another level of smoothing in avg_write_bandwidth.

2011-07-09writeback: make writeback_control.nr_to_write straightWu Fengguang
Pass struct wb_writeback_work all the way down to writeback_sb_inodes(), and initialize the struct writeback_control there. struct writeback_control is basically designed to control writeback of a single file, but we keep abuse it for writing multiple files in writeback_sb_inodes() and its callers. It immediately clean things up, e.g. suddenly wbc.nr_to_write vs work->nr_pages starts to make sense, and instead of saving and restoring pages_skipped in writeback_sb_inodes it can always start with a clean zero value. It also makes a neat IO pattern change: large dirty files are now written in the full 4MB writeback chunk size, rather than whatever remained quota in wbc->nr_to_write.

2011-07-09OMAP4: powerdomain data: Remove unsupported MPU powerdomain stateSantosh Shilimkar
On OMAP4430 devices, because of boot ROM code bug, MPU OFF state can't be attempted independently. When coming out of MPU OFF state, ROM code disables the clocks of IVAHD, TESLA which is not desirable. Hence the MPU OFF state is not usable on OMAP4430 devices. OMAP4460 onwards, MPU OFF state will be descoped completely because the DDR firewall falls in MPU power domain. When the MPU hit OFF state, DDR won't be accessible for other initiators. The deepest state supported is open switch retention (OSWR) just like CORE and PER PD on OMAP4430. So in summary MPU power domain OFF state is not supported on OMAP4 and onwards designs. Thanks to new PRCM design, device off mode can still be achieved with power domains hitting OSWR state.

2011-07-09OMAP4: clock data: Keep GPMC clocks always enabled and hardware managedSantosh Shilimkar
On OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by L3 interconnect. Because of CPU speculative nature, such accesses are possible which can lead to indirect access to GPMC and if it's clock is not running, it can result in hang/abort on the platform. Above makes access to GPMC unpredictable during the execution, so it's module mode needs to be kept under hardware control instead of software control. Since the auto gating is supported for GPMC, there isn't any power impact because of this change. The issue was un-covered with security middleware running along with HLOS. In this case GPMC had a valid MMU descriptor on secure side where as HLOS didn't map the GMPC because it isn't being used.

2011-07-09OMAP4: prcm: Fix errors in few defines nameBenoit Cousson
A couple of macros were wrongly changed during the _MOD to _INST rename done in the following commit: OMAP4: PRCM: rename _MOD macros to _INST cdb54c4457d68994da7c2e16907adfbfc130060d Fix them to their original name. Some CM and PRM instances were not well aligned. Align them. Remove one blank line in cm2_44xx.h to align the output with the other (cm1_44xx.h, prm44xx.h) files. Update header copyright date.

2011-07-09OMAP4: clock data: Fix max mult and div for USB DPLLBenoit Cousson
The DPLL USB can generate higher speed (x2) than the regular ones. The max multiplication value is then twice the previous value. Fix both max_mult and max_div with that correct values. Change the max_div variable type to u16 to allow storing up to 256. Replace as well the define with the value to avoid unneeded indirection and provide a better readability. Remove the defines that become useless.
