[ALSA] hda: ALC260 test model implementation
Modules: HDA Codec driver
The following patch adds a 'test' ALC260 model specification to the
patch_realtek.c driver if CONFIG_SND_DEBUG is set. This is similar to the
'test' ALC880 model in that it sets up mixer controls for almost everything
to make it easier for people to test their laptop/soundcard when working out
what pin widgets are connected to which real-world devices.
This patch assumes my previous patch (adding the second PCM to the ALC260)
has previously been applied since it uses infrastructure added by that
patch.
In developing this patch it was found that not all retasking pins accept all
the modes - in particular, some ignore the VREFxx variants. The pin mode
control has therefore been tweaked to prevent this becoming a problem in
mixer applications.

It is against alsa 1.0.11rc3.
Currently these widgets have their output muted, but a close reading of the
datasheet suggests that they don't actually have an output mute. They have
an *input* mute for each of their two inputs and a single output gain. This
patch therefore activates the input mutes and zeros the output gain. It has
not yet been tested but the above interpretation of the ALC260 datasheet

Modules: HDA Codec driver
The following patch against alsa 1.0.11rc3 creates a PCM device (pcm1c) for
the second ADC present on the ALC260 codec used by the hda driver. It also
defines a new mixer control allowing the mode of retasking pins to be set;
this means a user can (for example) designate the headphone jack to be a
second input. With this patch in place it is possible to do 4 channel
recording on laptops equipped with an ALC260 codec assuming both a stereo
line-in jack is provided in addition to a headphone jack.
Mixer controls are provided to allow the headphone jack to be switched as
an input. In addition, an (input only) mode control is configured for
the line-in jack to allow a bias voltage to be requested (VREF80 or VREF50)
so headsets based on condensor microphones have a chance of working.
This patch has been tested on a Fujitsu S7020 laptop and as such these
features are currently only configured for the 'fujitsu' model.

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

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

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.

While adding support for Zoom Video to the es18xx driver I found some of

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

[ALSA] Add support for EDIROL UM-3ex

This is my naive attempt at adding ALSA device support. The attached

UM-3x's in a master-slave configuration. I only have one, so I do not
know how this works in practice.
Though this is a 3-port device, I had to throw in that 4th 'Control' interface

[SPARC64]: Fix and re-enable dynamic TSB sizing.
This is good for up to %50 performance improvement of some test cases.
The problem has been the race conditions, and hopefully I've plugged
them all up here.
1) There was a serious race in switch_mm() wrt. lazy TLB
switching to and from kernel threads.
We could erroneously skip a tsb_context_switch() and thus
use a stale TSB across a TSB grow event.
There is a big comment now in that function describing
exactly how it can happen.
2) All code paths that do something with the TSB need to be
guarded with the mm->context.lock spinlock. This makes
page table flushing paths properly synchronize with both
TSB growing and TLB context changes.
3) TSB growing events are moved to the end of successful fault
processing. Previously it was in update_mmu_cache() but
that is deadlock prone. At the end of do_sparc64_fault()
we hold no spinlocks that could deadlock the TSB grow
sequence. We also have dropped the address space semaphore.
While we're here, add prefetching to the copy_tsb() routine
and put it in assembler into the tsb.S file. This piece of
code is quite time critical.
There are some small negative side effects to this code which
can be improved upon. In particular we grab the mm->context.lock
even for the tsb insert done by update_mmu_cache() now and that's
a bit excessive. We can get rid of that locking, and the same
lock taking in flush_tsb_user(), by disabling PSTATE_IE around
the whole operation including the capturing of the tsb pointer
and tsb_nentries value. That would work because anyone growing
the TSB won't free up the old TSB until all cpus respond to the
TSB change cross call.
I'm not quite so confident in that optimization to put it in
right now, but eventually we might be able to and the description
is here for reference.
This code seems very solid now. It passes several parallel GCC
bootstrap builds, and our favorite "nut cruncher" stress test which is
a full "make -j8192" build of a "make allmodconfig" kernel. That puts
about 256 processes on each cpu's run queue, makes lots of process cpu
migrations occur, causes lots of page table and TLB flushing activity,
incurs many context version number changes, and it swaps the machine
real far out to disk even though there is 16GB of ram on this test
system. :-)

The page->flags manipulations done by the D-cache dirty
state tracking was broken because the constants were not

This doesn't jive well with sparsemem which stores the

page->flags.
This is yet another sparc64 bug which has been with us
forever.
While we're here, tidy up some things in bootmem_init()

1) Pass min_low_pfn to init_bootmem_node(), it's identical
to (phys_base >> PAGE_SHIFT) but we should use consistent
with the variable names we print in CONFIG_BOOTMEM_DEBUG
2) max_mapnr, although no longer used, was being set
inaccurately, we shouldn't subtract pfn_base any more.

in arch/sparc64/kernel/entry.S, add prototypes to asm/hypervisor.h
2) Don't build and update the cpulist using inline functions, this
was causing the cpu mask to not get updated in the caller.
3) Disable interrupts during the entire mondo send, otherwise our
cpu list and/or mondo block could get overwritten if we take
an interrupt and do a cpu mondo send on the current cpu.
4) Check for all possible error return types from the cpu_mondo_send()
hypervisor call. In particular:
HV_EOK) Our work is done, all cpus have received the mondo.
HV_CPUERROR) One or more of the cpus in the cpu list we passed
to the hypervisor are in error state. Use cpu_state()
calls over the entries in the cpu list to see which
ones. Record them in "error_mask" and report this
after we are done sending the mondo to cpus which are
not in error state.
HV_EWOULDBLOCK) We need to keep trying.
Any other error we consider fatal, we report the event and exit
immediately.
5) We only timeout if forward progress is not made. Forward progress
is defined as having at least one cpu get the mondo successfully
in a given cpu_mondo_send() call. Otherwise we bump a counter
and delay a little. If the counter hits a limit, we signal an
error and report the event.
Also, smp_call_function_mask() error handling reports the number
of cpus incorrectly.
