X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4bade28288b12a6268d2e1fc2e4fa1f77ccb1d89;p=qemu.git Merge remote-tracking branch 'remotes/palmer/tags/riscv-for-master-4.1-sf0' into staging RISC-V Patches for the 4.1 Soft Freeze, Part 1 This tag contains a handful of patches that I'd like to target for 4.1: * An emulation for SiFive's GPIO device. * A fix to disallow sfence.vma from userspace. * Additional decodetree cleanups that should have no functional impact. * C extension emulation fidelity fixes that were noticed as part of that cleanup process. * A new "spike" target, along with the deprecation of a handful of old targets and CPUs. * Some initial infastructure related to the hypervisor extension. * An emulation fidelity fix that prevents prevents arbitrary bits in the SIP CSR from being set. * A small performance improvement that avoids excessive TLB flushing when the ASID does not change. This time I've used a new testing workflow: I've tested on both 32-bit and 64-bit builds of OpenEmbedded, via the default OpenSBI-based boot flow. # gpg: Signature made Sat 25 May 2019 01:05:57 BST # gpg: using RSA key 00CE76D1834960DFCE886DF8EF4CA1502CCBAB41 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt " [unknown] # gpg: aka "Palmer Dabbelt " [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 * remotes/palmer/tags/riscv-for-master-4.1-sf0: (29 commits) target/riscv: Only flush TLB if SATP.ASID changes target/riscv: More accurate handling of `sip` CSR target/riscv: Add checks for several RVC reserved operands target/riscv: Add the HGATP register masks target/riscv: Add the HSTATUS register masks target/riscv: Add Hypervisor CSR macros target/riscv: Allow setting mstatus virtulisation bits target/riscv: Add the MPV and MTL mstatus bits target/riscv: Improve the scause logic target/riscv: Trigger interrupt on MIP update asynchronously target/riscv: Mark privilege level 2 as reserved riscv: spike: Add a generic spike machine target/riscv: Deprecate the generic no MMU CPUs target/riscv: Add a base 32 and 64 bit CPU target/riscv: Create settable CPU properties riscv: virt: Allow specifying a CPU via commandline linux-user/riscv: Add the CPU type as a comment target/riscv: Remove unused include of riscv_htif.h for virt board riscv target/riscv: Remove spaces from register names target/riscv: Split gen_arith_imm into functional and temp ...
