* OMAP: DMA: Convert DMA library into platform driverG, Manjunath Kondaiah2010-12-20
| | | | | | | | | | | | | | | | Convert DMA library into DMA platform driver and make use of platform data provided by hwmod data base for OMAP2+ onwards. For OMAP1 processors, the DMA driver in mach-omap uses resource structures for getting platform data.

* OMAP: DMA: Introduce errata handling featureG, Manjunath Kondaiah2010-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | Implement errata handling to use flags instead of cpu_is_* and cpu_class_* in the code. The errata flags are initialized at init time and during runtime we are using the errata variable (via the IS_DMA_ERRATA macro) to execute the required errata workaround. Reused errata handling patch from: Peter Ujfalusi <peter.ujfalusi@nokia.com> https://patchwork.kernel.org/patch/231191/ Changes to above patch: 1. Changes are done for converting all the existing errata work arounds to use this feature. 2. Detailed description for each errata is added. 3. Fixed bug in SET_DMA_ERRATA macro 4.

* OMAP: DMA: Replace read/write macros with functionsG, Manjunath Kondaiah2010-12-20
| | | | | | | | | | | | | | | | | | | | | | Prepare DMA library to get converted into DMA driver using platform device model and hwmod infrastucture(for omap2+, resource structures for omap1) The low level read/write macros are replaced with static inline functions and register offsets are handled through static register offset tables mapped through enumeration constants. These low level read/write functions along with static register offset tables will be moved to respective mach-omap dma files in the later patches of this series. There are no functionality changes with these changes except change in logic for handling 16bit registers of OMAP1.

* OMAP3: DMA: Errata i541: sDMA FIFO draining does not finishPeter Ujfalusi2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the suggested workaround for OMAP3 regarding to sDMA draining issue, when the channel is disabled on the fly. This errata affects the following configuration: sDMA transfer is source synchronized Buffering is enabled SmartStandby is selected. The issue can be easily reproduced by creating overrun situation while recording audio. Either introduce load to the CPU: nice -19 arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null & \ dd if=/dev/urandom of=/dev/null or suspending the arecord, and resuming it: arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null CTRL+Z; fg; CTRL+Z; fg; ... In case of overrun audio stops DMA, and restarts it (without reseting the sDMA channel). When we hit this errata in stop case (sDMA drain did not complete), at the coming start the sDMA will not going to be operational (it is still draining). This leads to DMA stall condition. On OMAP3 we can recover with sDMA channel reset, it has been observed that by introducing unrelated sDMA activity might also help (reading from MMC for example). The same errata exists for OMAP2, where the suggestion is to disable the buffering to avoid this type of error. On OMAP3 the suggestion is to set sDMA to NoStandby before disabling the channel, and wait for the drain to finish, than configure sDMA to SmartStandby again.

* omap: dma: Fix buffering disable bit setting for omap24xxJarkko Nikula2010-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An errata workaround for omap24xx is not setting the buffering disable bit 25 what is the purpose but channel enable bit 7 instead. Background for this fix is the DMA stalling issue with ASoC omap-mcbsp driver. Peter Ujfalusi <peter.ujfalusi@nokia.com> has found an issue in recording that the DMA stall could happen if there were a buffer overrun detected by ALSA and the DMA was stopped and restarted due that. This problem is known to occur on both OMAP2420 and OMAP3. It can recover on OMAP3 after dma free, dma request and reconfiguration cycle. However, on OMAP2420 it seems that only way to recover is a reset. Problem was not visible before the commit c12abc0. That commit changed that the McBSP transmitter/receiver is released from reset only when needed. That is, only enabled McBSP transmitter without transmission was able to prevent this DMA stall problem in receiving side and underlying problem did not show up until now. McBSP transmitter itself seems to no be reason since DMA stall does not recover by enabling the transmission after stall. Debugging showed that there were a DMA write active during DMA stop time and it never completed even when restarting the DMA. Experimenting showed that the DMA buffering disable bit could be used to avoid stalling when using source synchronized transfers. However that could have performance hit and OMAP3 TRM states that buffering disable is not allowed for destination synchronized transfers so subsequent patch will implement a method to complete DMA writes when stopping. This patch is based on assumtion that complete lock-up on OMAP2420 is different but related problem. I don't have access to OMAP2420 errata but I believe this old workaround here is put for a reason but unfortunately a wrong bit was typed and problem showed up only now.

* OMAP2/3/4: DMA: disable channel interrupts in omap_init_dma()Mika Westerberg2010-05-20
| | | | | | | | | | | | | | | | | | | If we are softbooting another kernel using kexec, DMA controller state is not known when we are performing omap_init_dma(). It is possible that some DMA channels are already active. For example after kexec we get: <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 To prevent any weird things happening, we disable all channel interrupts during init.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

In order to avoid collision between kernel DMA transfers and ROM code dma transfers, we need to reserve DMA channels 0 1 on high security devices. A bug in ROM code leaves dma irq status bits uncleared. Hence those irq status bits need to be cleared when restoring DMA context after off mode. There was also a faulty parameter given to PPA in the secure ram context save assembly code, which caused interrupts to be enabled during secure ram context save. This caused the save to fail sometimes, which resulted the saved context to be corrupted, but also left DMA channels in secure mode. The secure mode DMA channels caused "DMA secure error with device 0" errors to be displayed.

Looking closer at this I have found that it had been broken almost 2 years ago with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1. The definite reason for broken omapfb/lcdc behavoiur in PM mode appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD DMA possibly running. The bit were set based on return value of the omap_dma_running() function that did not check for dedicated LCD DMA channel status. The patch below fixes this. Note that the hardcoded register value will be fixed during the next merge cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local to drivers/video/omap/lcdc.c, so let's not start moving those right now.

| | | | | | | | | | | | | Fix the possible race condition in omap_free_dma(). Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

* ARM: OMAP: Dispatch only relevant DMA interruptsSantosh Shilimkar2009-03-23
| | | | | | | | | | | | | | | | | | | This fixes the spurious interrupt issue on a DMA channel. In OMAP sDMA, contrast to the SDMA.DMA4_CSRi registers, the SDMA.DMA4_IRQSTATUS_Lj registers are updated regardless of the corresponding bits in the SDMA.DMA4_IRQENABLE_Lj registers. Since there are four sDMA interrupt lines and if more than one line is actively used by two concurrently running sDMA softwares modules,then the spurious interrupt can be observed on the other lines. Fix in this patch will only dispatch the relevant and enabled interrupts on a particular line thus perevting spurious IRQ.

It is needed since the OMAP DMA is a system wide resource and can be used by another software apart from the kernel. To reserve the omap SDMA channels for kernel dma usage, use cmdline bootarg "omap_dma_reserve_ch=". The valid range is 1 to 32.
