99cd49bb - crypto/nx: Register and unregister VAS interface on PowerVM

Thu, 17 Jun 2021 20:39:41 +0000

crypto/nx: Register and unregister VAS interface on PowerVMThe user space uses /dev/crypto/nx-gzip interface to setup VASwindows, create paste mapping and close windows. This patch addschanges to create/remove this interface with VAS register/unregisterfunctions on PowerVM platform.Signed-off-by: Haren Myneni Acked-by: Herbert Xu Acked-by: Nicholas Piggin Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/121ea1f4eb3004f3b8f4fe8abefaecc88b292efd.camel@linux.ibm.com List of files: /linux-6.15/drivers/crypto/nx/Kconfig

b0d6c9ba - crypto/nx: Add P9 NX support for 842 compression engine

Thu, 31 Aug 2017 07:19:07 +0000

crypto/nx: Add P9 NX support for 842 compression engineThis patch adds P9 NX support for 842 compression engine. VirtualAccelerator Switchboard (VAS) is used to access 842 engine on P9.For each NX engine per chip, setup receive window usingvas_rx_win_open() which configures RxFIFo with FIFO address, lpid,pid and tid values. This unique (lpid, pid, tid) combination willbe used to identify the target engine.For crypto open request, open send window on the NX engine forthe corresponding chip / cpu where the open request is executed.This send window will be closed upon crypto close request.NX provides high and normal priority FIFOs. For compression /decompression requests, we use only hight priority FIFOs in kernel.Each NX request will be communicated to VAS using copy/pasteinstructions with vas_copy_crb() / vas_paste_crb() functions.Signed-off-by: Haren Myneni Reviewed-by: Ram Pai Signed-off-by: Michael Ellerman List of files: /linux-6.15/drivers/crypto/nx/Kconfig

d31581a6 - crypto: nx - merge nx-compress and nx-compress-crypto

Wed, 22 Jul 2015 18:26:36 +0000

crypto: nx - merge nx-compress and nx-compress-cryptoMerge the nx-842.c code into nx-842-crypto.c.This allows later patches to remove the 'platform' driver, and insteadallow each platform driver to directly register with the cryptocompression api.Signed-off-by: Dan Streetman Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/nx/Kconfig

c47d6302 - crypto: nx - add LE support to pSeries platform driver

Thu, 18 Jun 2015 16:05:30 +0000

crypto: nx - add LE support to pSeries platform driverAdd support to the nx-842-pseries.c driver for running in little endianmode.The pSeries platform NX 842 driver currently only works as big endian.This adds cpu_to_be*() and be*_to_cpu() in the appropriate places towork in LE mode also.Signed-off-by: Dan Streetman Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/nx/Kconfig

596103cf - crypto: drivers - Fix Kconfig selects

Wed, 17 Jun 2015 06:58:24 +0000

crypto: drivers - Fix Kconfig selectsThis patch fixes a number of problems in crypto driver Kconfigentries:1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internaland should not be used outside of the crypto API itself.2. Do not select ALGAPI unless you use a legacy type likeCRYPTO_ALG_TYPE_CIPHER.3. Select the algorithm type that you are implementing, e.g., AEAD.4. Do not select generic C code such as CBC/ECB unless you use themas a fallback.5. Remove default n since that is the default default.Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/nx/Kconfig

ed70b479 - crypto: nx - add hardware 842 crypto comp alg

Thu, 07 May 2015 17:49:21 +0000

crypto: nx - add hardware 842 crypto comp algAdd crypto compression alg for 842 hardware compression and decompression,using the alg name "842" and driver_name "842-nx".This uses only the PowerPC coprocessor hardware for 842 compression. Italso uses the hardware for decompression, but if the hardware fails it willfall back to the 842 software decompression library, so that decompressionnever fails (for valid 842 compressed buffers). A header must be used inmost cases, due to the hardware's restrictions on the buffers beingspecifically aligned and sized.Due to the header this driver adds, compressed buffers it creates cannot bedirectly passed to the 842 software library for decompression. However,compressed buffers created by the software 842 library can be passed tothis driver for hardware 842 decompression (with the exception of bufferscontaining the "short data" template, as lib/842/842.h explains).Signed-off-by: Dan Streetman Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/nx/Kconfig

crypto: nx - add NX-842 platform frontend driverAdd NX-842 frontend that allows using either the pSeries platform orPowerNV platform driver (to be added by later patch) for the NX-842hardware.

0e16aafb - powerpc/crypto: add 842 hardware compression driver

Thu, 19 Jul 2012 14:42:40 +0000

powerpc/crypto: add 842 hardware compression driverThis patch adds the driver for interacting with the 842compression accelerator on IBM Power7+ systems.The device is a child of the Platform Facilities Option (PFO)and shows up as a child of the IBM VIO bus.The compression/decompression API takes the same argumentsas existing compression methods like lzo and deflate. The 842hardware operates on 4K hardware pages and the driver breaks upinput on 4K boundaries to submit it to the hardware accelerator.Signed-off-by: Robert Jennings Signed-off-by: Seth Jennings Signed-off-by: Herbert Xu List of files: /linux-6.15/drivers/crypto/nx/Kconfig
