  • 9004acc70   [ALSA] Remove sound/driver.h ... Browse Code »

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

    This patch enables wavetable chips ES689/ES69X connected to
    ESS ES18xx chips. The wavetable chip uses FM DAC if the clock signal
    from the wavetable is active.
    It has no effect if there is no ESS wavetable chip present.

  • 109c53f84   [ALSA] sound/isa: kill pnp_resource_change ... Browse Code »

    This removes the pnp_resource_change use from the ALSA ISAPnP drivers. In
    2.4 these were useful in providing an easy path to setting the resources,
    but in 2.6 they retain function as a layering violation only.
    This makes for a nice cleanup (-550 lines) of ALSA but moreover, ALSA is the
    only remaining user of pnp_init_resource_table(), pnp_resource_change() and
    pnp_manual_config_dev() (and, in fact, of 'struct pnp_resource_table') in
    the tree outide of drivers/pnp itself meaning it makes for more cleanup
    potential inside the PnP layer.
    Thomas Renninger acked their removal from that side, you did from the ALSA
    side (CC list just copied from that thread).
    Against current alsa-kernel HG. Many more potential cleanups in there, but
    this _only_ removes the pnp_resource_change code. Compile tested against
    current alsa-kernel HG and compile- and use-tested against 2.6.23.x (few
    offsets).

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    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 adds PnP BIOS support to es18xx driver. It allows ESS ES18xx sound
    chips integrated in some notebooks (such as DTK FortisPro TOP-5A) that don't
    appear as ISA cards (they aren't recognized by ISA PnP, only by PnP BIOS)
    to 'just work' automatically.

  • 95b712965   [ALSA] #4/4 for Zoom Video - add Zoom Video support ... Browse Code »

    Modules: ES18xx driver

    Forth of 4 es18xx.c patches culminating in Zoom Video support.

    This patch adds Zoom Video support for those chipsets that support it.

    Testing:
    This work was initially done on the source from the Debian Sarge ALSA
    package, then tested
    on an ES1879. I could not test the Zoom Video function for an ES1878 or
    ES1869.
    Patches were created against the Sarge code and then edited to apply
    correctly to the
    ALSA cvs code. Lastly the patched ALSA cvs code was test for successful
    compilation.
    No additional testing was done on the ALSA cvs version.

    One quirk (noted in my comments below) is that apparently the datasheet
    is wrong
    for one of the ES1879 Zoom Video 'enable' bits, because
    1) if you set this bit it messes up PCM playback (speaker_test play a
    lower frequency)
    2) even if you don't set this bit Zoom Video still works.
    I added a control to toggle the bit on just in case there might be a
    version of the
    ES1879 that requires it, but I expect noone will need it.

  • 14086771c   [ALSA] #3/4 for Zoom Video - change Hardware Volume interrupt handling ... Browse Code »

    Modules: ES18xx driver

    Third of 4 es18xx.c patches culminating in Zoom Video support.

    This patch changes the Hardware Volume support to reflect the fact that
    not all of the
    supported chipsets have seperate registers dedicated to the Hardware
    Volume inputs. Although
    all the chipsets can generate an HWV interrupt whenever a Hardware
    Volume input is received
    only those with seperate HWV registers can split the HWV registers from
    the Master volume
    registers.

    Testing:
    This work was initially done on the source from the Debian Sarge ALSA
    package, then tested
    on an ES1879 and an ES1878 machine. Patches were created against the
    Sarge code and then edited
    to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs
    code was test for
    successful compilation. No additional testing was done on the ALSA cvs
    version.

    Modules: ES18xx driver

    Second of 4 es18xx.c patches culminating in Zoom Video support.

    This patch changes the 'record source' mux routines to reflect the fact
    that not all of the
    supported chipsets have 8 possible inputs. Some have 4 and some have 5.

  • c1f6d4159   [ALSA] #1/4 for Zoom Video - resolve common vs chipset specific mixer controls ... Browse Code »

    Modules: ES18xx driver

    First of 4 es18xx.c patches culminating in Zoom Video support.
    While adding support for Zoom Video to the es18xx driver I found some of
    the mixer controls
    were wrong. Since you guys went to the trouble of supplying the
    datasheets for the supported
    chipsets I did a review of all of them and tried to get es18xx.c to
    accurately reflect the
    proper mixer controls for each chipset. If the datasheets are wrong then
    so are my patches.

    This first patch moves some controls from the common-to-all-chipsets array
    'snd_es18xx_base_controls' to a chipset-specific array and adds code to
    manage that new array.
    Also while testing on my ES1878 test machine I discovered it needed a
    couple of udelays in
    the identify function so those are in this patch as well.

    Testing:
    This work was initially done on the source from the Debian Sarge ALSA
    package, then tested
    on an ES1879 and an ES1878 machine. Patches were created against the
    Sarge code and then edited
    to apply correctly to the ALSA cvs code. Lastly the patched ALSA cvs
    code was test for
    successful compilation. No additional testing was done on the ALSA cvs
    version.

    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!
