[PATCH] crypto: hisilicon/hpre - fix unmapping invalid dma address

Currently, an invalid dma address may be unmapped when calling 'xx_data_clr_all' in error path, so check dma address of sqe in/out whether it has been mapped before calling 'dma_free_coherent' or 'dma_unmap_single'. An abnormal case is as follows: hpre_curve25519_compute_value -> hpre_curv

[PATCH v3] crypto: hisilicon/hpre - delete redundant log and return in advance

'hpre_cfg_by_dsm' has checked and printed error path internally. It is not necessary to do it here, so remove it. It should return error immediately when return value of 'hpre_cfg_by_dsm' is non-zero, and no need to execute the remaining sentences. Signed-off-by: Hui Tang --- v1 -> v2: - Ret

[PATCH 00/16] Enable VAS and NX-GZIP support on powerVM

This patch series enables VAS / NX-GZIP on powerVM which allows the user space to do copy/paste with the same existing interface that is available on powerNV. VAS Enablement: - Get all VAS capabilities using H_QUERY_VAS_CAPABILITIES that are available in the hypervisor. These capabilities tell

[PATCH 01/16] powerpc/powernv/vas: Rename register/unregister functions

powerNV and pseries drivers register / unregister to the corresponding VAS code separately. So rename powerNV VAS API register/unregister functions. Signed-off-by: Haren Myneni --- arch/powerpc/include/asm/vas.h | 6 +++--- arch/powerpc/platforms/powernv/vas-api.c | 10 +- d

[PATCH 02/16] powerpc/vas: Make VAS API powerpc platform independent

Using the same /dev/crypto/nx-gzip interface for both powerNV and pseries. So this patcb moves VAS API to powerpc platform indepedent directory. The actual functionality is not changed in this patch. Signed-off-by: Haren Myneni --- arch/powerpc/Kconfig | 15 + arch

[PATCH 03/16] powerpc/vas: Create take/drop task reference functions

Take task reference when each window opens and drops during close. This functionality is needed for powerNV and pseries. So this patch defines the existing code as functions in powerpc platform independent vas-api.c Signed-off-by: Haren Myneni --- arch/powerpc/include/asm/vas.h |

[PATCH 04/16] powerpc/vas: Move update_csb/dump_crb to platform independent

NX issues an interrupt when sees fault on user space buffer. The kernel processes the fault by updating CSB. This functionality is same for both powerNV and pseries. So this patch moves these functions to vas-api.c and the actual functionality is not changed. Signed-off-by: Haren Myneni --- ar

[PATCH 05/16] powerpc/vas: Define and use common vas_window struct

Same vas_window struct is used on powerNV and pseries. So this patch changes in struct vas_window to support both platforms and also the corresponding modifications in powerNV vas code. On powerNV vas_window is used for both TX and RX windows, whereas only for TX windows on powerVM. So some elem

[PATCH 07/16] powerpc/vas: Define QoS credit flag to allocate window

pHyp introduces two different type of credits: Default and Quality of service (QoS). The total number of default credits available on each LPAR depends on CPU resources configured. But these credits can be shared or over-committed across LPARs in shared mode which can result in paste command fai

[PATCH 08/16] powerpc/pseries/VAS: Implement allocate/modify/deallocate HCALLS

This patch adds the following HCALLs which are used to allocate, modify and deallocate VAS windows. H_ALLOCATE_VAS_WINDOW: Allocate VAS window H_DEALLOCATE_VAS_WINDOW: Close VAS window H_MODIFY_VAS_WINDOW: Setup window before using Also adds phyp call (H_QUERY_VAS_CAPABILITIES) to get all VAS c

[PATCH 09/16] powerpc/pseries/vas: Implement to get all capabilities

pHyp provides various VAS capabilities such as GZIP default and QoS capabilities which are used to determine total number of credits available in LPAR, maximum window credits, maximum LPAR credits, whether usermode copy/paste is supported, and etc. So first retrieve overall vas capabilities usin

[PATCH 10/16] powerpc/pseries/vas: Integrate API with open/close windows

This patch adds VAS window allocatioa/close with the corresponding HCALLs. Also changes to integrate with the existing user space VAS API and provide register/unregister functions to NX pseries driver. The driver register function is used to create the user space interface (/dev/crypto/nx-gzip)

[PATCH 11/16] powerpc/pseries/vas: Setup IRQ and fault handling

When NX sees a fault on the user space buffer, generates a fault interrupt and pHyp forwards that interrupt to OS. Then the kernel makes H_GET_NX_FAULT HCALL to retrieve the fault CRB information. This patch adds changes to setup IRQ per each window and handles fault by updating CSB. Signed-off

[PATCH 12/16] powerpc/pseries/vas: sysfs interface to export capabilities
