* dev_vdbg(), available with -DVERBOSE_DEBUGDavid Brownell2007-07-181-7/+0
| | | | | | | | | | | | | | | | | | | | | This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG. When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved out of a USB patch, but lots of drivers have similar support. That is, code can now be written to use an additional level of debug output, selected at compile time. Many driver authors have found this idiom to be very useful. A typical usage model is for "normal" debug messages to focus on fault paths and not be very "chatty", so that those messages can be left on during normal operation without much of a performance or syslog load. On the other hand "verbose" messages would be noisy enough that they wouldn't normally be enabled; they might even affect timings enough to change system or driver behavior.

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-174-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

| | | | | | | | | | | | | | Although the other USB driver directories got taught how use Kconfig and the Makefile to enable the debugging messages enabled by -DDEBUG, the gadget stack was overlooked.

* usb gadget stack: remove usb_ep_*_buffer(), part 2David Brownell2007-07-129-429/+0
| | | | | | | | | | | | | | | | | | | | This patch removes controller driver infrastructure which supported the now-removed usb_ep_{alloc,free}_buffer() calls. As can be seen, many of the implementations of this were broken to various degrees. Many didn't properly return dma-coherent mappings; those which did so were necessarily ugly because of bogosity in the underlying dma_free_coherent() calls ... which on many platforms can't be called from the same contexts (notably in_irq) from which their dma_alloc_coherent() sibling can be called. The main potential downside of removing this is that gadget drivers wouldn't have specific knowledge that the controller drivers have: endpoints that aren't dma-capable don't need any dma mappings at all.

* usb gadget stack: remove usb_ep_*_buffer(), part 1David Brownell2007-07-124-29/+11
| | | | | | | | | | | | | | | | | | | | | | Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement. Note that the gmidi.c driver had a bug in this area; fixed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: pxa2xx_udc -- cleanups, mostly removing dma hooksDavid Brownell2007-07-122-404/+25
| | | | | | | | | | | | | | | | | | | | Cleanups to the pxa2xx_udc code: - Primarily removing unused DMA hooks. - One "sparse" warning removed - Remove some Lubbock-only LED hooks (for debugging) That DMA code was never really completed. It worked, mostly, for IN transfers (to the host) if they were fortuitously aligned, but that code was never fully tested. And it was never coded for OUT transfers (which is where DMA would really help) ... because of chip errata on essentially every chip other than the pxa255, and because of design botches (nothing automated data toggle). So it's effectively been dead code for several years now ... no point in keeping it around.

* USB: usb/dma doc updatesDavid Brownell2007-07-121-5/+6
| | | | | | | | | | | | | | | | | | | | | | This patch updates some of the documentation about DMA buffer management for USB, and ways to avoid extra copying. Our understanding of the issues has improved over time. - Most drivers should *avoid* the dma-coherent allocators. There are a few exceptions (like the HID driver). - Some methods are currently commented out; it seems folk writing USB drivers aren't doing performance tuning at that level yet. - Just avoid highmem; there's no good way to pass an "I can do highmem DMA" capability through a driver stack. This is easy, everything already avoids highmem. But it'd be nice if x86_32 systems with much physical memory could use it directly with network adapters and mass storage devices. (Patch, anyone?)

Since I combed a few small bugs away, this also fixes the small races we had in usblp for a while. For example, now it's possible for several threads to make write(2) calls (sounds silly, but consider a printer for paper record, where every line of text is self-contained and thus it's all right to have them interleaved). Also gone are issues with interrupts using barriers dangerously. This patch makes use of Oliver's anchor, and so it must trail the anchor patch on the way to Linus.

| | | | | | | | | | | | | | | | | | Use the baud rate stuff from the kernel don't parse CBAUD directly Remove pointless and wrong 'no change' check Could do with some good testing as well but again better than adding && BROKEN (The use of BELKIN_SA_BAUD() might seem a bit odd but x/a = b and x/b = a (rounded for integers)).

| | | | | | | | | | | | | | | | o Don't parse the cflag for baud rates, its not valid to do so any more and this driver got it wrong anyway o Don't do clever termios change checks in drivers and get them wrong (arguably we should do some smart ones in the tty core but stty to change nothing is *not* a common or critical path I don't have the hardware so if you can test this carefully please do. I thought fixing it up this far was better than marking it and other bits of USB serial && BROKEN Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
