2008-11-11V4L/DVB (9516): cx18: Move DVB buffer transfer handling from irq handler to ↵Andy Walls
work_queue cx18: Move DVB buffer transfer handling from irq handler to work_queue thread. In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue. This work_queue implmentation is strikingly similar to the ivtv implementation - for better or worse.

2008-11-11V4L/DVB (9515): cx18: Use correct Mailbox IRQ Ack values and misc IRQ ↵Andy Walls
handling cleanup cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanup. The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling logic. Renamed fields in SCB to make things consistent and did misc IRQ handling cleanups: removing legacy ivtv dma_reg_lock, HPU IRQ flags, etc. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

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.

2008-10-21V4L/DVB (9297): cx18: Fix memory leak on card initialization failureAndy Walls
On error exit, the cx18_probe() function did not use the proper entry in cx18_cards[] with kfree() when card init failed; leaking memory. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
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.

2008-10-12V4L/DVB (9131): cx18: Add entries for the Leadtek PVR2100 and Toshiba Qosmio ↵Andy Walls
DVB-T/Analog cx18: Add entries for the Leadtek PVR2100 and Toshiba Qosmio DVB-T/Analog capture cards. Both cards are hybrids cards, but no digital capture functionality has been added yet. 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. Martin Juhl <mj at casalogic.dk>, an owner of the Toshiba DVB-T/Analog tuner card, provided the DDR timing information from his Windows inf file.

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.

cx18: Correct CX23418 PCI configuration settings. The CX23418 doesn't have I/O space registers, so there was no need to try and turn them on (the card ignores the attempt to set the bit anyway).
