2007-08-03ivtv: attach yuv field order to each frameHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> In the current driver, the field order is global. As soon as it's changed it takes immediate effect. This is a problem when the video changes order mid stream. Although it mostly works okay, the video may judder / flicker. This patch attaches the field order to the frame, so that any buffered frames will not be displayed until the correct field. In the event that the field order is changed mid stream, the driver will ensure that the previous frame is displayed for a minimum of 3 fields. These are the two original fields the frame should have occupied, plus the one extra since the new frame still has to wait for the correct field.

2007-08-03ivtv: prevent yuv register updates from being missedHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> The yuv output code always compares the new frame position & size with those of the previous frame. If they are different, a flag is set to request the yuv output registers be updated when the new frame is displayed. If the incoming frames are delivered too fast, exhausting the buffers, the most recent frame already buffered will be discarded. Unfortunately, any update request will also be discarded. If the new frame matches the size & position of the now discarded frame, the yuv registers are not flagged for update & will remain in their old state. This patch preserves the register update flag in the event that a frame is dropped. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-03ivtv-fb: framebuffer timings no longer locked on module loadHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> Framebuffer timings are currently locked to the video format in use when the module is loaded. If the video format is then changed, the timings returned by the framebuffer will be for the original format. This patch ensures that the timings returned reflect the current video format.

2007-08-03ivtv: prevent vertical overflow of yuv outputHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> When the video standard is changed, there's no guarantee the framebuffer dimensions are still legal. The yuv output code uses these dimensions to calculate the size & position for the video overlay. If the framebuffer dimensions are now illegal, the output may exceed the vertical limit of the display, causing distortion. This patch adds an additional check to ensure the output doesn't exceed the limits for the current video standard, cropping if required.

From: Hans Verkuil <hverkuil@xs4all.nl> While decoding (MPEG or YUV) is active or when VBI output is in use, then do not clear the VBI output of the saa7127. Only after the last user is gone can we clear it. This fixes the case where playback was stopped, another channel was chosen and playback was restarted, while /dev/vbi16 was used to set the WSS (widescreen) setting. Without this fix the WSS was reset on every stop instead of just keeping the last value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-07-21bttv: Fix Viewcast Osprey 440 supportTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Various gpio and mux settings for the Osprey 440 weren't correct. Fix them and provide some documentation about how the gpios work. The osprey eeprom routine wasn't run for the 440, add it. It was also crap, re-written to be better. Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample rate is fixed at 32kHz, as the driver doesn't support different rates for digital input mode, though the card can select the rate from 32, 44.1, or 48 kHz via gpio. Setting the audio gain via ALSA isn't supported yet; a userspace tool that programs the X9221 via i2c-dev must be used. The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC used, resulting in extremely garbled sound. That is fixed in a followup patch.

From: Mauro Carvalho Chehab <mchehab@infradead.org> backport patch from Auke Kok <auke-jan.h.kok@intel.com>: PCI: Change all drivers to use pci_device->revision Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

2007-07-19backport kernel commit 59faba1b316a7798a33752b3889193333f8af1a0Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Original patch from Trent Piepho <xyzzy@speakeasy.org>. Its description: Fix Kconfig dependency problems wrt boolean menuconfigs If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool promotes the tristate from m to y. This ends up causing a problem with several menuconfigs that look like: menuconfig BAR bool depends on BAZ [tristate] if BAR config FOO tristate endif The solution used here is to add the dependencies of BAR to the if statement, so that items in the if block will gain a direct non-bool-promoted dependency on BAZ. This is how it would work if a menu was used instead of an if block. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-07-19backport kernel changeset 831441862956fffa17b9801db37e6ea1650b0f69Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> kernel-sync: Original patch description from the patch by Rafael J. Wysocki <rjw@sisk.pl>: Freezer: make kernel threads nonfreezable by default Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
