      ALSA: mpu401: clean up interrupt specification · dba8b469
      Clemens Ladisch 提交于
      The semantics of snd_mpu401_uart_new()'s interrupt parameters are
      somewhat counterintuitive:  To prevent the function from allocating its
      own interrupt, either the irq number must be invalid, or the irq_flags
      parameter must be zero.  At the same time, the irq parameter being
      invalid specifies that the mpu401 code has to work without an interrupt
      allocated by the caller.  This implies that, if there is an interrupt
      and it is allocated by the caller, the irq parameter must be set to
      a valid-looking number which then isn't actually used.
      
      With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,
      which forces us to handle the parameters differently.
      
      This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the
      device interrupt is handled by the caller, and makes the allocation of
      the interrupt to depend only on the irq parameter.  As suggested by
      Takashi, the irq_flags parameter was dropped because, when used, it had
      the constant value IRQF_DISABLED.

      ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/* · 934c2b6d
      Takashi Iwai 提交于
      The name argument of request_irq() appears in /proc/interrupts, and
      it's quite ugly when the name entry contains a space or special letters.
      In general, it's simpler and more readable when the module name appears
      there, so let's replace all entries with KBUILD_MODNAME.

      ALSA: Use KBUILD_MODNAME for pci_driver.name entries · 3733e424
      Takashi Iwai 提交于
      The convention for pci_driver.name entry in kernel drivers seem to be
      the module name or equivalent ones.  But, so far, almost all PCI sound
      drivers use more verbose name like "ABC Xyz (12)", and these are fairly
      confusing when appearing as a file name.
      
      This patch converts the all pci_driver.name entries in sound/pci/* to
      use KBUILD_MODNAME for more unified appearance.

      ALSA: ice1712 delta - initialize SPI clock · b8b1a4cb
      Brian Bloniarz 提交于
      The driver was using an initial value for the clock on the SPI bus
      which was read from ICE1712 EEPROM,
      ice->eeprom.data[ICE_EEP1_GPIO_STATE] & ICE1712_DELTA_AP_CCLK (0x02)
      
      It appears some cards have it default high, some cards
      have it default low. On my Delta 66 rev. E:
      $ cat /proc/asound/M66/ice1712 | grep 'GPIO state'
        GPIO state       : 0x70 /* ICE1712_DELTA_AP_CCLK bit is zero */
      On my Audiophile 2496:
      $ cat /proc/asound/M2496/ice1712 | grep 'GPIO state'
        GPIO state       : 0xfe /* ICE1712_DELTA_AP_CCLK bit is one */
      
      It must be raised before the first SPI write happens, or the write will
      fail, leading to:

      I theorize that 4eb4550a
      is no longer needed, it was a different way to workaround
      the problem.

      ALSA: ice1712 - working M-Audio Delta 66E support · 93430096
      Brian Bloniarz 提交于
      Rev. E of the M-Audio Delta 66 is partially supported (commit
      ef2cd2cc), but the layout of the GPIO
      pins was still unclear. This patch adds the GPIO definitions so that
      communication to the CS8247 & 2x AK4524 works correctly.
      
      ALSA bug#3327 has more details; users cap & jhunt report there that the
      GPIO wiring is similar to the Digigram VX442 (chip select: pin 4 =
      CS8427, pin 5 = AK4524 #0, pin 6 = AK4524 #1).  There has been a lot of
      conflicting information in the bug, but given these definitions, my
      Delta 66E works; I tested analog in&out at 44.1kHz & 96kHz, analog gain
      settings, S/PDIF clock sync, and S/PDIF in&out at 44.1kHz.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo 提交于
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.
