2009-07-21Use dst_type field instead of type_flagsMauro Carvalho Chehab
From: Julia Lawall <julia@diku.dk> It seems from other code that it is the dst_type field rather than the type_flags field that contains values of the form DST_TYPE_IS... The type_flags field contains values of the form DST_TYPE_HAS... The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct dst_state E; @@ ( *E.type_flags == \( DST_TYPE_IS_SAT\|DST_TYPE_IS_TERR\|DST_TYPE_IS_CABLE\|DST_TYPE_IS_ATSC \) | *E.type_flags != \( DST_TYPE_IS_SAT\|DST_TYPE_IS_TERR\|DST_TYPE_IS_CABLE\|DST_TYPE_IS_ATSC \) ) // </smpl> CC: Manu Abraham <abraham.manu@gmail.com> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-03-20Kconfig: replace all occurrences of CUSTOMIZE to CUSTOMISEMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> There are several Kconfig items using CUSTOMIZE. Yet, most use the English writing CUSTOMISE. This generates lots of trouble, because people sometimes type the Kbuild item different. Let's standardise every occurrence using the same syntax. The changes were generated by this small shell script: for i in `find linux -type f`; do sed s,CUSTOMIZE,CUSTOMISE,g $i >/tmp/a && mv /tmp/a $i; done Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-05-06Fix FW_LOADER depencency at v4l/dvbMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Since: 1) FW_LOADER is defined as: config FW_LOADER tristate "Userspace firmware loading support" depends on HOTPLUG 2) several V4L/DVB driver just selects it; 3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER. So, All drivers that select FW_LOADER should also depend on HOTPLUG. An easier solution (for the end-user perspective) would be to "select HOTPLUG". However, live is not simple. This would cause recursive dependency issues like this one: drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD -> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA -> USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

Move tuners to common/tuners There were several issues in the past, caused by the hybrid tuner design, since now, the same tuner can be used by drivers/media/dvb and drivers/media/video. This patch moves those common tuners into a common dir. It also moves saa7146 driver into drivers/media/video, where other hybrid drivers are placed. Kconfig items were rearranged, to split V4L/DVB core from their drivers. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-04-09Adds selectable adapter numbers as per module optionMichael Krufky
From: Janne Grunau <janne-dvb@grunau.be> The adapter_nr module options can be used to allocate static adapter numbers on a driver level. It avoids problems with changing DVB apapter numbers after warm/cold boot or device unplugging and repluging. Each driver holds DVB_MAX_ADAPTER long array of the preferred order of adapter numbers. options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a reversed allocation of adapter numbers. With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If both are already in use it will allocate the lowest free adapter number.

2007-02-27dvb: Remove lgh06xf driverTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The code of the dvb-pll driver and the lgh06xf driver is nearly identical. The main difference is that the lgh06xf driver would set the AGC TOP value on every tune call. The dvb-pll driver now has the ability to set the AGC TOP when the front-end device is opened, which is a better way to go about it. By using this ability of dvb-pll, the lgh06xf driver is made unnecessary. There is one other difference. dvb-pll will probe for the presence of an I2C pll chip by doing a one byte read, the lgh06xf driver did not do this. In some devices the PLL is not reachable over I2C at the timer the tuner is attached. Some more initialization, such as firmware loading, must take place first. None of the devices using a LG-H06xF should have this problem. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Michael Krufky <mkrufky@linuxtv.org>

From: "Robert P. J. Day" <rpjday@mindspring.com> Run this: ============== cut here ============== for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work. kernel-sync: Signed-off-by: Andrew Morton <akpm@osdl.org> CC: v4l-dvb maintainer list <v4l-dvb-maintainer@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-11-19create new lgh06xf atsc tuner moduleMichael Krufky
From: Michael Krufky <mkrufky@linuxtv.org> This patch creates a new atsc tuner module for the LG TDVS-H06xF ATSC tuners, called lgh06xf. The purpose of this change is to reduce some duplicated code, and to allow the lgh06xf tuner code to take advantage of dvb_attach(). As a side effect, the dependency of dvb-bt8xx on dvb-pll has been removed, since the lgh06xf module itself will use dvb-pll, while remaining optional for the dvb-bt8xx driver through the use of DVB_FE_CUSTOMISE Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Acked-by: Andrew de Quincey <adq_dvb@lidskialf.net>
2006-10-21IRQ: Maintain regs pointer globally rather than passing to IRQ handlersMauro Carvalho Chehab
Kernel-sync: This patch is required to allow compilation of the tree with kernel 2.6.19. This is the original description of the original patch, signed by David Howells <dhowells@redhat.com>: 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. Signed-Off-By: Mauro Carvalho Chehab <mchehab@infradead.org>
