2022-09-04target/openrisc: Enable MTTCGStafford Horne1-0/+1
This patch enables multithread TCG for OpenRISC. Since the or1k shared syncrhonized timer can be updated from each vCPU via helpers we use a mutex to synchronize updates. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Stafford Horne <shorne@gmail.com>

Add LoongArch flatted device tree, adding cpu device node, firmware cfg node, pcie node into it, and create fdt rom memory region. Now fdt info is not full since only uefi bios uses fdt, linux kernel does not use fdt. Loongarch Linux kernel uses acpi table which is full in qemu virt machine.

2022-02-26hw/openrisc/openrisc_sim: Add automatic device tree generationStafford Horne1-0/+1
Using the device tree means that qemu can now directly tell the kernel what hardware is configured rather than use having to maintain and update a separate device tree file. This patch adds automatic device tree generation support for the OpenRISC simulator. A device tree is built up based on the state of the configure openrisc simulator. This is then dumped to memory and the load address is passed to the kernel in register r3. Signed-off-by: Stafford Horne <shorne@gmail.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org>

2021-11-02target/arm: Advertise MVE to gdb when presentPeter Maydell4-4/+4
Cortex-M CPUs with MVE should advertise this fact to gdb, using the org.gnu.gdb.arm.m-profile-mve XML feature, which defines the VPR register. Presence of this feature also tells gdb to create pseudo-registers Q0..Q7, so we do not need to tell gdb about them separately. Note that unless you have a very recent GDB that includes this fix: http://patches-tcwg.linaro.org/patch/58133/ gdb will mis-print the individual fields of the VPR register as zero (but showing the whole thing as hex, eg with "print /x $vpr" will give the correct value).

2021-09-30target/arm: Don't put FPEXC and FPSID in org.gnu.gdb.arm.vfp XMLPeter Maydell4-4/+4
Currently we send VFP XML which includes D0..D15 or D0..D31, plus FPSID, FPSCR and FPEXC. The upstream GDB tolerates this, but its definition of this XML feature does not include FPSID or FPEXC. In particular, for M-profile cores there are no FPSID or FPEXC registers, so advertising those is wrong. Move FPSID and FPEXC into their own bit of XML which we only send for A and R profile cores. This brings our definition of the XML org.gnu.gdb.arm.vfp feature into line with GDB's own (at least for non-Neon cores...) and means we don't claim to have FPSID and FPEXC on M-profile. (It seems unlikely to me that any gdbstub users really care about being able to look at FPEXC and FPSID; but we've supplied them to gdb for a decade and it's not hard to keep doing so.)

The aarch64-linux QEMU usermode binaries can never run 32-bit code, so they do not need to include the GDB XML for it. (arm_cpu_register_gdb_regs_for_features() will not use these XML files if the CPU has ARM_FEATURE_AARCH64, so we will not advertise to gdb that we have them.)
