Subject: sparc64: Add detection for features new in SPARC-T4.

Compare and branch, pause, and the various new cryptographic opcodes.

We advertise the crypto opcodes to userspace using one hwcap bit,
HWCAP_SPARC_CRYPTO.

This essentially indicates that the %cfr register can be interrograted
and used to determine exactly which crypto opcodes are available on
the current cpu.

We use the %cfr register to report all of the crypto opcodes available
in the bootup CPU caps log message, and via /proc/cpuinfo.

Subject: sparc64: Add hypervisor interfaces for SPARC-T4 perf counter access.

Unlike for previous chips, access to the perf-counter control
registers are all hyper-privileged.  Therefore, access to them must go
through a hypervisor interface.

Subject: sparc64: Abstract away PIC register accesses.

And, like for the PCR, allow indexing of different PIC register
numbers.

This also removes all of the non-__KERNEL__ bits from asm/perfctr.h,
nothing kernel side should include it any more.

Subject: sparc64: Abstract away the %pcr values used to enable/disable NMI

We assumed PCR_PIC_PRIV can always be used to disable it, but that
won't be true for SPARC-T4.

This allows us also to get rid of some messy defines used in only
one location.

This is enough to get the NMIs working, more work is needed
for perf events.

Subject: sparc64: Add perf_event abstractions for orthogonal PMUs.

Starting with SPARC-T4 we have a seperate PCR control register
for each performance counter, and there are absolutely no
restrictions on what events can run on which counters.

Add flags that we can use to elide the conflict and dependency
logic used to handle older chips.

Subject: sparc64: Prepare perf event layer for handling multiple PCR
 registers.

Make the per-cpu pcr save area an array instead of one u64.

Describe how many PCR and PIC registers the chip has in the sparc_pmu
descriptor.

Subject: sparc64: Rework sparc_pmu_enable() so that the side effects are
 clearer.

When cpuc->n_events is zero, we actually don't do anything and we just
write the cpuc->pcr[0] value as-is without any modifications.

The "pcr = 0;" assignment there was just useless and confusing.

Subject: sparc64: Update generic comments in perf event code to match reality.

Describe how we support two types of PMU setups, one with a single control
register and two counters stored in a single register, and another with
one control register per counter and each counter living in it's own
register.

  * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
  * unusual way to encode a NOP and therefore will not trigger in
  * normal code.
+ *
+ * Starting with SPARC-T4 we have one control register per counter.

Subject: sparc64: Use fsrc2 instead of fsrc1 in sparc64 hash crypto drivers.

On SPARC-T4 fsrc2 has 1 cycle of latency, whereas fsrc1 has 11 cycles.

True story.

From 0bdcaf7495726688a93a2f7226e9b4beaeabd2ec Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>
Date: Wed, 29 Aug 2012 12:50:16 -0700
Subject: sparc64: Move AES driver over to a methods based implementation.

Instead of testing and branching off of the key size on every
encrypt/decrypt call, use method ops assigned at key set time.

Reverse the order of float registers used for decryption to make
future changes easier.

Align all assembler routines on a 32-byte boundary.

Subject: sparc64: Unroll ECB encryption loops in AES driver.

The AES opcodes have a 3 cycle latency, so by doing 32-bytes at a
time we avoid a pipeline bubble in between every round.

For the 256-bit key case, it looks like we're doing more work in
order to reload the KEY registers during the loop to make space
for scarce temporaries.  But the load dual issues with the AES
operations so we get the KEY reloads essentially for free.

Before:

testing speed of ecb(aes) encryption
test 0 (128 bit key, 16 byte blocks): 1 operation in 264 cycles (16 bytes)
test 1 (128 bit key, 64 byte blocks): 1 operation in 231 cycles (64 bytes)
test 2 (128 bit key, 256 byte blocks): 1 operation in 329 cycles (256 bytes)
test 3 (128 bit key, 1024 byte blocks): 1 operation in 715 cycles (1024 bytes)
test 4 (128 bit key, 8192 byte blocks): 1 operation in 4248 cycles (8192 bytes)
test 5 (192 bit key, 16 byte blocks): 1 operation in 221 cycles (16 bytes)
test 6 (192 bit key, 64 byte blocks): 1 operation in 234 cycles (64 bytes)
test 7 (192 bit key, 256 byte blocks): 1 operation in 359 cycles (256 bytes)
test 8 (192 bit key, 1024 byte blocks): 1 operation in 803 cycles (1024 bytes)
test 9 (192 bit key, 8192 byte blocks): 1 operation in 5366 cycles (8192 bytes)
test 10 (256 bit key, 16 byte blocks): 1 operation in 209 cycles (16 bytes)
test 11 (256 bit key, 64 byte blocks): 1 operation in 255 cycles (64 bytes)
test 12 (256 bit key, 256 byte blocks): 1 operation in 379 cycles (256 bytes)
test 13 (256 bit key, 1024 byte blocks): 1 operation in 938 cycles (1024 bytes)
test 14 (256 bit key, 8192 byte blocks): 1 operation in 6041 cycles (8192 bytes)

After:

testing speed of ecb(aes) encryption
test 0 (128 bit key, 16 byte blocks): 1 operation in 266 cycles (16 bytes)
test 1 (128 bit key, 64 byte blocks): 1 operation in 256 cycles (64 bytes)
test 2 (128 bit key, 256 byte blocks): 1 operation in 305 cycles (256 bytes)
test 3 (128 bit key, 1024 byte blocks): 1 operation in 676 cycles (1024 bytes)
test 4 (128 bit key, 8192 byte blocks): 1 operation in 3981 cycles (8192 bytes)
test 5 (192 bit key, 16 byte blocks): 1 operation in 210 cycles (16 bytes)
test 6 (192 bit key, 64 byte blocks): 1 operation in 233 cycles (64 bytes)
test 7 (192 bit key, 256 byte blocks): 1 operation in 340 cycles (256 bytes)
test 8 (192 bit key, 1024 byte blocks): 1 operation in 766 cycles (1024 bytes)
test 9 (192 bit key, 8192 byte blocks): 1 operation in 5136 cycles (8192 bytes)
test 10 (256 bit key, 16 byte blocks): 1 operation in 206 cycles (16 bytes)
test 11 (256 bit key, 64 byte blocks): 1 operation in 268 cycles (64 bytes)
test 12 (256 bit key, 256 byte blocks): 1 operation in 368 cycles (256 bytes)
test 13 (256 bit key, 1024 byte blocks): 1 operation in 890 cycles (1024 bytes)
test 14 (256 bit key, 8192 byte blocks): 1 operation in 5718 cycles (8192 bytes)

Subject: sparc64: Fix bugs in unrolled 256-bit loops.

Some dm-crypt testing revealed several bugs in the 256-bit unrolled
loops.

The DECRYPT_256_2() macro had two errors:

1) Missing reload of KEY registers %f60 and %f62

2) Missing "\" in penultimate line of definition.

In aes_sparc64_ecb_decrypt_256, we were storing the second half of the
encryption result from the wrong source registers.

In aes_sparc64_ctr_crypt_256 we have to be careful when we fall out of
the 32-byte-at-a-time loop and handle a trailing 16-byte chunk.  In
that case we've clobbered the final key holding registers and have to
restore them before executing the ENCRYPT_256() macro.  Inside of the
32-byte-at-a-time loop things are OK, because we do this key register
restoring during the first few rounds of the ENCRYPT_256_2() macro.

Subject: sparc64: Support 2GB and 16GB page sizes for kernel linear mappings.

SPARC-T4 supports 2GB pages.

So convert kpte_linear_bitmap into an array of 2-bit values which
index into kern_linear_pte_xor.

Now kern_linear_pte_xor is used for 4 page size aligned regions,
4MB, 256MB, 2GB, and 16GB respectively.

Enabling 2GB pages is currently hardcoded using a check against
sun4v_chip_type.  In the future this will be done more cleanly
by interrogating the machine description which is the correct
way to determine this kind of thing.

Subject: sparc64: Probe cpu page size support more portably.

On sun4v, interrogate the machine description.  This code is extremely
defensive in nature, and a lot of the checks can probably be removed.

On sun4u things are a lot simpler.  There are the page sizes all chips
support, and then Panther adds 32MB and 256MB pages.

Report the probed value in /proc/cpuinfo

From c69ad0a3f7d871aa61fb669fb41c951df6660a61 Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@davemloft.net>
Date: Thu, 6 Sep 2012 20:35:36 -0700
Subject: sparc64: Use cpu_pgsz_mask for linear kernel mapping config.

This required a little bit of reordering of how we set up the memory
management early on.

We now only know the final values of kern_linear_pte_xor[] after we
take over the trap table and start processing TLB misses ourselves.

So once we fill those values in we re-clear the kernel's 4M TSB and
flush the TLBs.  That way if we find we support larger than 4M pages
we won't have any stale smaller page size entries in the TSB.

SUN4U Panther support for larger page sizes should now be extremely
trivial but I have no hardware on which to test it and I believe
that some of the sun4u TLB miss assembler needs to be audited first
to make sure it really can handle larger than 4M PTEs properly.

Subject: sparc64: Adjust crypto priorities.

Make the crypto opcode implementations have a higher priority than
those provides by the ring buffer based Niagara crypto device.

Also, several crypto opcode hashes were not setting the priority value
at all.

Subject: sparc64: Add auto-loading mechanism to crypto-opcode drivers.

Just simply provide a device table containing an entry for sun4v cpus,
the capability mask checks in the drivers themselves will take care of
the rest.

This makes the bootup logs on pre-T4 cpus slightly more verbose, with
each driver indicating lack of support for the associated opcode(s).

But this isn't too much of a real problem.

I toyed with the idea of using explicit entries with compatability
fields of "SPARC-T4", "SPARC-T5", etc. but all future cpus will have
some subset of these opcodes available and this would just be one more
pointless thing to do as each new cpu is released with a new string.

Subject: sparc64: Fix IV handling bug in des_sparc64_cbc_decrypt

The IV wasn't being propagated properly past the first loop
iteration.

This bug lived only because the crypto layer tests for
cbc(des) do not have any cases that go more than one loop.
