2008-10-21V4L/DVB (9299): cx18: Don't mask many real init error codes by mapping them ↵Andy Walls
to ENOMEM Changes to let error return codes bubble up to the user visible error message on card initialization. A number of them were being remapped to ENOMEM when no memory or array resource shortage existed. That hampered diagnosis of user trouble reports.

2008-10-12V4L/DVB (9133): v4l: disconnect kernel number from minorHans Verkuil
The v4l core creates four different video devices (video, vbi, radio, vtx) and each has its own range of minor numbers. However, modern devices keep increasing the number of devices that they need so a maximum of 64 video devices will not be enough in the future. In addition this scheme makes it very hard to add new device types. This patch disconnects the kernel number allocation (e.g. video0, video1, etc.) from the actual minor number (just pick the first free minor). This allows for much more flexibility in the future. However, it does require the use of udev. For those who cannot use udev a new CONFIG option was created that changes the allocation scheme back to the old behavior. Thanks to Greg KH for suggesting this approach during the 2008 LPC. In addition, several bugs were fixed in the ivtv and cx18 drivers: these drivers try to allocate specific kernel numbers but that scheme contained a bug which caused what should have been e.g. video17 to appear as e.g. video2.

These entries are a first guess at the card entries to get analog working, given the information available. Terry Wu <terrywu at leadtek.com.tw> provided a pointer to information for the PVR2100.

2008-10-12V4L/DVB (9111): cx18: Up the version to 1.0.1Andy Walls
cx18: Up the version to 1.0.1. This will make it easy to tell if retries of MMIO access are implemented or not in trouble reports. First course of action for I2C and other initialization problem reports will be to have user upgrade to v1.0.1 of driver.

2008-10-12V4L/DVB (9110): cx18: Add default behavior of checking and retrying PCI MMIO ↵Andy Walls
accesses cx18: Add default behavior of checking and retrying PCI MMIO accesses. The concept of checking and retrying PCI MMIO accesses for better reliability in older motherboards was suggested by Steve Toth <stoth@linuxtv.org>. This change implements MMIO retries and the retry_mmio module parameter that is enabled by default. Limited experiments have shown this is more reliable than the mmio_ndelay parameter. mmio_ndelay has insignificant effect with retries enabled.

2008-10-12V4L/DVB (8914): cx18: Throttle mmio to/from the CX23418 so boards work in ↵Andy Walls
older systems cx18: Throttle mmio to/from the CX23418 so boards work in older systems. The CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was attempting to access the chip. The PCI bridge arrangements and settings on modern motherboards still allowed the CX23418 to work OK, but it didn't work well on many older motherboards: mysterious I2C errors, firmware loading errors, etc. This patch adds a throttle to *all* mmio access to the CX23418. It defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm. My HVR-1600 and Raptor PAL/SECAM card now function for analog capture on a motherboard with an Intel 82810E Northbridge and 82801AA Southbridge.

2008-10-12V4L/DVB (8774): cx18: Have CX23418 release buffers at end of capture.Andy Walls
cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
