2020-06-04KVM: MIPS: Add CPUCFG emulation for Loongson-3Huacai Chen1-0/+11
Loongson-3 overrides lwc2 instructions to implement CPUCFG and CSR read/write functions. These instructions all cause guest exit so CSR doesn't benifit KVM guest (and there are always legacy methods to provide the same functions as CSR). So, we only emulate CPUCFG and let it return a reduced feature list (which means the virtual CPU doesn't have any other advanced features, including CSR) in KVM.

2018-12-08mips: bpf: fix encoding bug for mm_srlv32_opJiong Wang1-1/+1
For micro-mips, srlv inside POOL32A encoding space should use 0x50 sub-opcode, NOT 0x90. Some early version ISA doc describes the encoding as 0x90 for both srlv and srav, this looks to me was a typo. I checked Binutils libopcode implementation which is using 0x50 for srlv and 0x90 for srav. v1->v2: - Keep mm_srlv32_op sorted by value.

2017-11-02License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman1-0/+1
Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

2017-09-06MIPS: microMIPS: Fix decoding of swsp16 instructionMatt Redfearn1-1/+1
When the immediate encoded in the instruction is accessed, it is sign extended due to being a signed value being assigned to a signed integer. The ISA specifies that this operation is an unsigned operation. The sign extension leads us to incorrectly decode: 801e9c8e: cbf1 sw ra,68(sp) As having an immediate of 1073741809. Since the instruction format does not specify signed/unsigned, and this is currently the only location to use this instuction format, change it to an unsigned immediate.

Emulate the HYPCALL instruction added in the VZ ASE and used by the MIPS paravirtualised guest support that is already merged. The new hypcall.c handles arguments and the return value. No actual hypercalls are yet supported, but this still allows us to safely step over hypercalls and set an error code in the return value for forward compatibility. Non-zero HYPCALL codes are not handled. We also document the hypercall ABI which asm/kvm_para.h uses.
