* V4L/DVB (12262): em28xx: Make sure the tuner is initialized if generic empia ↵Devin Heitmueller2009-07-241-0/+1
| | | | | | | | | | | | | | | | | | | USB id was used In cases where the device has a generic Empia USB ID, the call in the precard setup phase did not set the tuner GPIO. As a result, the tuner may not be taken out of reset before attempting initialization in the analog driver. This problem was not seen before with the EVGA inDtube, since that particular board has the analog GPIO setup to include taking the tuner out of reset.

* V4L/DVB (12244): em28xx: adjust vinmode/vinctl based on the stream input formatMauro Carvalho Chehab2009-07-243-14/+17
| | | | | | | | | Depending on the video input format, vinmode/vinctl needs adjustments. For TV, this is not relevant, since the supported decoders output data at the same format. However, webcam sensors may have different formats, so, this needs to be adjusted based on the device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (12243): em28xx: allow specifying sensor xtal frequencyMauro Carvalho Chehab2009-07-242-3/+10
| | | | | | | | | | | | | | In order to properly estimate fps, mt9v011 sensor driver needs to know what is the used frequency on the sensor cristal. Adds the proper fields and initialization code for specifying the cristal frequency. Also, based on experimentation, it was noticed that the Silvercrest is outputing data at 7 fps. This means that it should be using a 6.3 MHz cristal. This information needs to be double checked later, by opening the device. Anyway, by using this value for xtal, at least now we have the correct fps report. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | It is possible to adjust the fps rate by changing some register values. This is function of the connected Xtal at the camera sensor, being a 27 MHz cristal needed, in order to support 640x480 at 30 fps. For now, it will only calculate the values for fps. Later patches may introduce V4L2 ioctls, to allow frequency rate adjustments. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (12239): em28xx: fix webcam scalingMauro Carvalho Chehab2009-07-244-24/+18
| | | | | | | | | | | | | | | While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do work with em28xx + webcam. The issue is that the scaling setup depends on the number of visible rows/cols of the input image. With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling is different from a normal TV image (720x480 on NTSC). This were causing a wrong scaling and a previous patch disabled scaling. As each sensor have their different resolution setting, the xres/yres should be adjusted accordingly with the input sensor. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (12238): em28xx: call sensor detection code for all webcam entriesMauro Carvalho Chehab2009-07-241-9/+9
| | | | | | | | | | | | With the previous approach, autodetection were working only for the two generic entries (em275x and em2820 unknown ones). So, if someone would try to force probing an specific device, the code would not properly run the autodetection code. With the new approach, the sensor autodetection will be run not only for the two generic entries, but also do webcam specific ones. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for some reason, this structure gets compiled as 36 bytes in some files (the ones that alloacte it) but 40 bytes in others (the ones that use it). The cause is an off_t type that gets a different size in different compilation units for some yet-to-be-explained reason. But the effect is disasterous; the size/offset members of the struct are at different offsets, and result in mostly complete garbage. The parser in perf is so robust that this all gets hidden, and after skipping an certain amount of samples, it recovers.... so this bug is not normally noticed. .... except when you want every sample to be exact.

His suggestion was to always return the parent counter id, since that is the primary counter id as exposed. However, these inherited counters have a unique identifier so that events like PERF_EVENT_PERIOD and PERF_EVENT_THROTTLE can be specific about which counter gets modified, which is important when trying to normalize the sample streams. This patch removes PERF_EVENT_PERIOD in favour of PERF_SAMPLE_PERIOD, which is more useful anyway, since changing periods became a lot more common than initially thought -- rendering PERF_EVENT_PERIOD the less useful solution (also, PERF_SAMPLE_PERIOD reports the more accurate value, since it reports the value used to trigger the overflow, whereas PERF_EVENT_PERIOD simply reports the requested period changed, which might only take effect on the next cycle). This still leaves us PERF_EVENT_THROTTLE to consider, but since that _should_ be a rare occurrence, and linking it to a primary id is the most useful bit to diagnose the problem, we introduce a PERF_SAMPLE_STREAM_ID, for those few cases where the full reconstruction is important.

| | * | strlist: Introduce strlist__entry and strlist__nr_entries methodsArnaldo Carvalho de Melo2009-07-112-4/+27

We now keep the nr_entries so that we can check if we have just one entry, will be used in 'perf report' to improve the output by showing just at the top when we have just, say, one DSO. While at it use nr_entries to optimize strlist__is_empty by not using the far more costly rb_first based implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ingo noticed that both AMD and P6 call x86_pmu_disable_counter() on *_pmu_enable_counter(). This is because we rely on the side effect of that call to program the event config but not touch the EN bit. We change that for AMD by having enable_all() simply write the full config in, and for P6 by explicitly coding it.
