2011-10-21crypto: twofish - add 3-way parallel x86_64 assembler implementionJussi Kivilinna
Patch adds 3-way parallel x86_64 assembly implementation of twofish as new module. New assembler functions crypt data in three blocks chunks, improving cipher performance on out-of-order CPUs. Patch has been tested with tcrypt and automated filesystem tests. Summary of the tcrypt benchmarks: Twofish 3-way-asm vs twofish asm (128bit 8kb block ECB) encrypt: 1.3x speed decrypt: 1.3x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CBC) encrypt: 1.07x speed decrypt: 1.4x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CTR) encrypt: 1.4x speed Twofish 3-way-asm vs AES asm (128bit 8kb block ECB) encrypt: 1.0x speed decrypt: 1.0x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CBC) encrypt: 0.84x speed decrypt: 1.09x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CTR) encrypt: 1.15x speed Full output: http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-3way-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-aes-asm-x86_64.txt Tests were run on: vendor_id : AuthenticAMD cpu family : 16 model : 10 model name : AMD Phenom(tm) II X6 1055T Processor Also userspace test were run on: vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E7330 @ 2.40GHz stepping : 11 Userspace test results: Encryption/decryption of twofish 3-way vs x86_64-asm on AMD Phenom II: encrypt: 1.27x decrypt: 1.25x Encryption/decryption of twofish 3-way vs x86_64-asm on Intel Xeon E7330: encrypt: 1.36x decrypt: 1.36x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

of crypto_tfm This needed by 3-way twofish patch to be able to easily use one block assembler functions. As glue code is shared between i586/x86_64 apply change to i586 assembler too.

2011-10-21crypto: blowfish-x86_64 - improve x86_64 blowfish 4-way performanceJussi Kivilinna
This patch adds improved F-macro for 4-way parallel functions. With new F-macro for 4-way parallel functions, blowfish sees ~15% improvement in speed tests on AMD Phenom II (~5% on Intel Xeon E7330). However when used in 1-way blowfish function new macro would be ~10% slower than original, so old F-macro is kept for 1-way functions. Patch cleans up old F-macro as it is no longer needed in 4-way part. Patch also does register macro renaming to reduce stack usage.

Patch adds x86_64 assembly implementation of blowfish. Two set of assembler functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'four-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 4-way functions should be equal to 1-way functions with in-order CPUs.

2011-08-10crypto: sha1 - SSSE3 based SHA1 implementation for x86-64Mathias Krause
This is an assembler implementation of the SHA1 algorithm using the Supplemental SSE3 (SSSE3) instructions or, when available, the Advanced Vector Extensions (AVX). Testing with the tcrypt module shows the raw hash performance is up to 2.3 times faster than the C implementation, using 8k data blocks on a Core 2 Duo T5500. For the smalest data set (16 byte) it is still 25% faster. Since this implementation uses SSE/YMM registers it cannot safely be used in every situation, e.g. while an IRQ interrupts a kernel thread. The implementation falls back to the generic SHA1 variant, if using the SSE/YMM registers is not possible. With this algorithm I was able to increase the throughput of a single IPsec link from 344 Mbit/s to 464 Mbit/s on a Core 2 Quad CPU using the SSSE3 variant -- a speedup of +34.8%. Saving and restoring SSE/YMM state might make the actual throughput fluctuate when there are FPU intensive userland applications running. For example, meassuring the performance using iperf2 directly on the machine under test gives wobbling numbers because iperf2 uses the FPU for each packet to check if the reporting interval has expired (in the above test I got min/max/avg: 402/484/464 MBit/s). Using this algorithm on a IPsec gateway gives much more reasonable and stable numbers, albeit not as high as in the directly connected case. Here is the result from an RFC 2544 test run with a EXFO Packet Blazer FTB-8510: frame size sha1-generic sha1-ssse3 delta 64 byte 37.5 MBit/s 37.5 MBit/s 0.0% 128 byte 56.3 MBit/s 62.5 MBit/s +11.0% 256 byte 87.5 MBit/s 100.0 MBit/s +14.3% 512 byte 131.3 MBit/s 150.0 MBit/s +14.2% 1024 byte 162.5 MBit/s 193.8 MBit/s +19.3% 1280 byte 175.0 MBit/s 212.5 MBit/s +21.4% 1420 byte 175.0 MBit/s 218.7 MBit/s +25.0% 1518 byte 150.0 MBit/s 181.2 MBit/s +20.8% The throughput for the largest frame size is lower than for the previous size because the IP packets need to be fragmented in this case to make there way through the IPsec tunnel.

2011-07-30m68k/atari: Reserve some ST-RAM early on for device buffer useMichael Schmitz
Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: Michael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

2011-07-28ARM: zynq: remove incorrectly deleted fileArnd Bergmann
My previous commit left the file empty and present in the Makefile, which is a bit dirty and caused problems with 'make distclean', as pointed out by David Howells. This hopefully cleans it up the right way. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David Howells <dhowells@redhat.com> Acked-by: John Linn <john.linn@xilinx.com>

2011-07-28at91: use structure to store the current socJean-Christophe PLAGNIOL-VILLARD
instead of reading the registers everytime the current implementation respect the following constrain: - allow 1 to n soc to be enabled - allow to have a virtual cpu type and subtype - always detect the cpu type and subtype and report it - detect if the soc support is enabled - prepare for sysfs export support - drop soc specific code via compiler when the soc not enabled (via cpu_is_xxx) Today if we read the exid we will have the same value for 9g35 and 9m11 and we will need to check the cidr too with the new implementation we just need to check the soc subtype this will also allow to have specific virtual subtype for rm9200 which the board will have to specify via at91rm9200_set_type(int) as we have no way to detect it. this implementation is inspired by the SH cpu detection support Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Patrice Vilchez <patrice.vilchez@atmel.com>
