2008-10-12V4L/DVB (9129): zoran: move zoran sources into a zoran subdirectoryHans Verkuil1-1747/+0
Prevent the zoran driver sources from cluttering the video directory. This changeset only moves the drivers and it does not fix any of the checkpatch warnings/errors to keep the changeset clean.

2008-10-12V4L/DVB (8906): v4l-dvb: fix assorted sparse warningsHans Verkuil1-2/+0
Fix sparse warnings. None are serious, but cutting down on these helps find future serious sparse warnings/errors. Redid the av7710.c patch based on a suggestion by Oliver Endriss. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-12V4L/DVB (8729): Use DIV_ROUND_UPJulia Lawall1-2/+2
The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable.

Thanks to Martin Michlmayr <tbm@cyrius.com> for reporting this issue: The zoran driver fails to compile on the ARM Orion platform with: In file included from drivers/media/video/zoran_procfs.c:50: drivers/media/video/zoran.h:232: error: expected identifier before numeric constant The reason is that drivers/media/video/zoran.h defines an enum with GPIO_MAX in it, but Orion contains a #define GPIO_MAX 32 in include/asm-arm/arch-orion/orion.h Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-09V4L/DVB (5885): zr36067: Fix problems with module parametersTrent Piepho1-1/+1
Add permissions to all the module parameters so they can be queried and set (when possible) via sysfs. Add description for the vidmem parameter. Change the video_nr parameter to an array, so that the video number can be specified when a user has more than one card. The driver would try to give all cards the same number otherwise, which will fail for all cards after the first. The default_input option would only allow values of 0 or 1, contrary to the description. Allow values up to the number of inputs defined for the card. Add description of lock_norm's different behavior for 1 and >1. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Ronald S.

2007-10-09V4L/DVB (5884): zr36067: clean up debug functionJean Delvare1-12/+5
Debugging cleanups to the zr36067 driver: * Use module_param_named() to declare the debug parameter, so we can use a single global variable to handle the debug level. This makes the driver a bit smaller (by 648 bytes on x86_64), thanks to one less level of indirection on every use. * Change the debug parameter sysfs permissions, so that the debug level can be adjusted at runtime, as is done in many other media/video drivers. * The debug level is between 0 and 5, not 0 and 4. * Move the zr_debug export and dprintk macro definition to a header file so that we don't have to define them in each source file. * Simplify a duplicate test on zr_debug. Note that zr_debug was subsequently renamed to debug_zr36067 to avoid possible conflicts with other Zoran device drivers, on a suggestion by Trent Piepho.

2007-07-30V4L/DVB (5891): zr36067: Turn off raw capture properlyTrent Piepho1-5/+12
When raw capture was turned off, the current capturing frame (v4l_grab_frame) wasn't reset to NO_GRAB_ACTIVE. If capture was turned back on, the driver would think this frame was currently being captured, and wait for it to complete before starting a new frame. The hardware on the other hand would not be actively capturing a frame. The result was the driver would wait forever for v4l_grab_frame to be captured. Some calls to zr36057_set_memgrab(0) were missing spin-locks, which have been added. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Ronald S.

2007-07-30V4L/DVB (5890): zr36067: Add UYVY, RGB555X, RGB565X, and RGB32 formatsTrent Piepho1-32/+1
Add support for the UYVY and the other big endian output formats. The driver was naming formats based on the host endianess. This is different that all the other drivers appear to work and not what software appears to expect. Use ARRAY_SIZE() to find the the size of the zoran_formats array. Change the way the driver handles setting the video format register. Rather than use some if and switch statements to set to register by looking at the format id, the format list simply has a field with the proper bits to set. Adds a bit of ifdef to make a driver without V4L1 support more possible. Also create a macro for defining formats that handles vl41 and/or vl42 support to avoid repeated ifdefs in the format list.

2006-10-06Various drivers' irq handlers: kill dead code, needless castsJeff Garzik1-1/+1
- Eliminate casts to/from void* - Eliminate checks for conditions that never occur. These typically fall into two classes: 1) Checking for 'dev_id == NULL', then it is never called with NULL as an argument. 2) Checking for invalid irq number, when the only caller (the system) guarantees the irq handler is called with the proper 'irq' number argument.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-2/+1
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
