2011-10-31drivers/media: Add module.h to all files using it implicitlyPaul Gortmaker1-0/+1

2011-09-03[media] saa7146: Use current logging stylesJoe Perches1-35/+39
Standardize the mechanisms to emit logging messages. A few other modules used an #include from saa7146, convert those at the same time. Add pr_fmt. Convert printks to pr_<level> Convert printks without KERN_<level> to appropriate pr_<level>. Convert logging macros requiring multiple parentheses to normal style. Removed embedded prefixes when pr_fmt was added. Whitespace cleanups when around other conversions. Use printf extension %pM to print mac address. Coalesce format strings.

Two fixes for the 'saa7146_wait_for_debi_done' code: (a) Timeout did not work when the routine was called with interrupts disabled. (b) Reduce PCI I/O load caused by saa7146_wait_for_debi_done.

2007-10-09V4L/DVB (6252): Adapt drivers to use the newer videobuf modulesMauro Carvalho Chehab1-1/+1
PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo. Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct. So, to access it, a subroutine call is needed. This patch renames all occurences of those function calls to be consistent with the video-buf split.

2007-05-09V4L/DVB (5592): DMA: Correctly free resources on error, sync PCI streamed dataJon Burgess1-19/+35
I added saa7146_vmalloc_destroy_pgtable() which frees the resources allocated by saa7146_vmalloc_build_pgtable() and updated the callers in budget-core.c and av7110.c. I have also been through the updated functions and updated the error paths to ensure they free all allocated resources on error. I also realised that there are other callers to saa7146_pgtable_free() which did not have any sg DMA mapped so it seems wrong to add the pci_unmap_sg() into that function. Instead I created saa7146_vmalloc_destroy_pgtable() to do this. Also included in this patch are the previous fixes for pci_unmap_sg() and syncing the PCI streamed data to work with a SWIOTLB and match the requirements documented in DMA-API.txt.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-1/+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.

This patch does a full cleanup of 'NULL checks before vfree', and a partial cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in that I only did the files that also had vfree calls in them.

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!
