target/mips: Don't check COP1X for 64 bit FP mode

2022-11-08T00:04:25+00:00

Some implementations (i.e. Loongson-2F) may decide to implement a 64 bit FPU without implementing COP1X instructions. As the eligibility of 64 bit FP instructions is already determined by CP0St_FR, there is no need to check for COP1X again.

target/mips: Enable LBX/LWX/* instructions for Octeon

2022-11-08T00:04:25+00:00

This patch changes condition and function name for enabling indexed load instructions for Octeon vCPUs. Octeons do not have DSP extension, but implement LBX-and-others.

target/mips: Cast offset field of Octeon BBIT to int16_t

2022-11-08T00:04:25+00:00

As per "Cavium Networks OCTEON Plus CN50XX Hardware Reference Manual" offset field is signed 16 bit value. However arg_BBIT.offset is unsigned. We need to cast it as signed to do address calculation.

accel/tcg: Introduce tb_pc and log_pc

2022-10-04T19:13:12+00:00

The availability of tb->pc will shortly be conditional. Introduce accessor functions to minimize ifdefs. Pass around a known pc to places like tcg_gen_code, where the caller must already have the value. Reviewed-by: Alex Bennée Signed-off-by: Richard Henderson

target/mips: Honour -semihosting-config userspace=on

2022-09-13T16:18:21+00:00

Honour the commandline -semihosting-config userspace=on option, instead of always permitting userspace semihosting calls in system emulation mode, by passing the correct value to the is_userspace argument of semihosting_enabled(). Note that this is a behaviour change: if the user wants to do semihosting calls from userspace they must now specifically enable them on the command line. MIPS semihosting is not implemented for linux-user builds.

target/mips: Handle lock_user() failure in UHI_plog semihosting call

2022-08-08T21:22:36+00:00

Coverity notes that we forgot to check the error return from lock_user() in one place in the handling of the UHI_plog semihosting call. Add the missing error handling. report_fault() is rather brutal in that it will call abort(), but this is the same error-handling used in the rest of this file.
