95b712965f [ALSA] #4/4 for Zoom Video - add Zoom Video support
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.

14086771c0 [ALSA] #3/4 for Zoom Video - change Hardware Volume interrupt handling
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.

This work was initially done on the source from the Debian Sarge ALSA

f4df221f8f [ALSA] #2/4 for Zoom Video - resolve number of record sources
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.

c1f6d41593 [ALSA] #1/4 for Zoom Video - resolve common vs chipset specific mixer controls
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.

This work was initially done on the source from the Debian Sarge ALSA
package, then tested

e03173fce2 [ALSA] Add support for EDIROL UM-3ex
Modules: USB generic driver

This is my naive attempt at adding ALSA device support. The attached
patch provides support for the EDIROL UM-3ex. This is a 3-port USB midi
interface with a built-in USB hub and the ability to chain 2 other
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
to the definition in order to make the 3rd port work. If I set in/out_cables
to 0x000b, a 3rd interface appears on the driver, but it does nothing.
Changing it to 0x000f allows the 3rd interface to work, but of course
interface 4 does not work because it does not exist.

a91690ddd0 [SPARC64]: Top-down address space allocation for 32-bit tasks.
Currently allocations are very constrained for 32-bit processes.
It grows down-up from 0x70000000 to 0xf0000000 which gives about
2GB of stack + dynamic mmap() space.

So support the top-down method, and we need to override the
generic helper function in order to deal with D-cache coloring.

With these changes I was able to squeeze out a mmap() just over
3.6GB in size in a 32-bit process.

7a1ac52641 [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. :-)

72b845e04e [TG3]: Do not try to access NIC_SRAM_DATA_SIG on Sun parts.
Sun does't put an SEEPROM behind the tigon3 chip, among other things,
so accesses to these areas just give bus timeouts.

0c51ed93ca [SPARC64]: First cut at VIS simulator for Niagara.
Niagara does not implement some of the VIS instructions in
hardware, so we have to emulate them.

90a6646bf6 [SPARC64]: Fix system type in /proc/cpuinfo and remove bogus OBP check.
Report 'sun4v' when appropriate in /proc/cpuinfo

Remove all the verifications of the OBP version string.  Just
make sure it's there, and report it raw in the bootup logs and
via /proc/cpuinfo.

8935dced54 [SPARC64]: Add SMT scheduling support for Niagara.
The mapping is a simple "(cpuid >> 2) == core" for now.
Later we'll add more sophisticated code that will walk
the sun4v machine description and figure this out from
there.

We should also add core mappings for jaguar and panther
processors.

17b0e199a1 [SPARC64]: Fix 32-bit truncation which broke sparsemem.
The page->flags manipulations done by the D-cache dirty
state tracking was broken because the constants were not
marked with "UL" to make them 64-bit, which means we were
clobbering the upper 32-bits of page->flags all the time.

This doesn't jive well with sparsemem which stores the
section and indexing information in the top 32-bits of
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()
and paginig_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.

3) All the games with phys_base in the zones_*[] arrays
   we pass to free_area_init_node() are no longer necessary.

Thanks to Josh Grebe and Fabbione for the bug reports
and testing.  Fix also verified locally on an SB2500
which had a memory layout that triggered the same problem.

d1112018b4 [SPARC64]: Move over to sparsemem.
This has been pending for a long time, and the fact
that we waste a ton of ram on some configurations
kind of pushed things over the edge.
