* [media] tda18271: allow restricting max out to 4 bytesMauro Carvalho Chehab2010-10-20
| | | | | | | | | | | | | | | By default, tda18271 tries to optimize I2C bus by updating all registers at the same time. Unfortunately, some devices doesn't support it. The current logic has a problem when small_i2c is equal to 8, since there are some transfers using 11 + 1 bytes. Fix the problem by enforcing the max size at the right place, and allows reducing it to max = 3 + 1.

This helps to detect when the driver is using the wrong I2C bus (or have the i2g gate switch pointing to the wrong place), on devices like cx231xx that just return 0 on reads to a non-existent i2c device.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tda18271_rf_tracking_filters_init While having tda18271 module set with debug=17 (cal & info prints) and cal=0 (delay calibration process until first use) - I discovered that during the calibration process, if the frequency test for 69750000 returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that the tuner wouldn't be able to pickup any of the frequencies in the range (all the other frequencies bands returned bcal=1). I spent some time going over the code and the NXP's tda18271 spec (ver.4 of it i think) and adding a lot of debug prints and walking/stepping through the calibration process. I found that when the powerscan fails to find a frequency, the rf calibration is not run and the default value is supposed to be used in its place (pulled from the RF_CAL_map table) - but something was getting goofed up there. Now, my c coding skills are very rusty, but i think root of the problem is a signedness issue with the math operation for calculating the rf_a1 and rf_a2 values in tda18271_rf_tracking_filters_init func, which results in values like 20648 for rf_a1 (when it should probably have a value like 0, or so slightly negative that it should be zero - this bad value for rf_a1 would in turn makes the approx calc within tda18271c2_rf_tracking_filters_correction go out of whack). The simplest solution i found was to explicitly convert the signedness of the denominator to avoid the implicit conversion. The values placed into the u32 rf_freq array should never exceed about 900mhz, so i think the s32 max value shouldn't be an issue in this case. I've tested it out a little, and even when i get a bcal=0 with the modified code, the default calibration value gets used, rf_a1 is zero, and the tuner seems to lock on the stream and mythtv seems to play it fine.
