2008-01-21 bt878: remove handcrafted PCI subsystem ID checkMauro Carvalho Chehab
From: Akinobu Mita <akinobu.mita@gmail.com> This patch moves the subsystem ID and subsystem vendor ID check from probing function to the PCI generic function by describing subsystem IDs in pci_device_id table. This enables to add new PCI IDs to a device driver pci_ids table at runtime by new_id file in sysfs pci driver tree.

2007-04-14Bt878: prevent probing wrong card entryMauro Carvalho Chehab
From: Akinobu Mita <akinobu.mita@gmail.com> I got strange message when I did modprobe bt878: bt878_probe: card id=[0x0],[ <NULL> ] has DVB functions. The card_list array is terminated by sentinel entry. But this list is traversed by: for (i = 0, dvb_cards = card_list; i < ARRAY_SIZE(card_list); i++, dvb_cards++) { ... } in bt878_probe(). So this loop checks dummy sentinel entry, too. This patch removes unnecessary sentinel entry.

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>

load skystar2 driver from insmod.sh script
2003-10-28- reworked i2c / gpio so not so hackerish and more in line withJamie Honan
what Gerd is moving to - allowed multiple instances of dst frontend. - should handle terrestial cards correctly. Can mix and match ts204, new tuner packets, symbol rate types in tuner packets - has more DST strings on i2c asic discovery (in dst_check_ci) - can override card PCI id using card=0x68 for bttv driver. bt878 audio dma still hogs all cards it finds, but this is an interim release to work towards fixing this - put in rudimentary signal strength / snr. The scale factors are not right. Should work for terrestial / satellite. - Put in Dimitri's fix of not doing dst_enable after reciept of the 0xFF ack, but allowing the asic to do this itself.
2003-10-13Changes to support dst and bttv > 0.9.12 and for kernel >= 2.6.0-test7Jamie Honan
This has support for i2c doen by bttv. Tested and working in 2.4, clean compile 2.6. Expect changes to get working under 2.6. Patches directory no longer needed.

- use c99 initializers - remove blank lines - remove bt848.h -- it's already in driver/media/video (this probably breaks 2.4 compilation)

2003-06-21- 2.5 API changes for bt878Holger Waechtler
- remove flush_workqueue(wq) from dvb_net.c -- don't we have to ensure that the handler has finished? all other drivers don't do this as well...?
