2022-09-04target/openrisc: Enable MTTCGStafford Horne
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>
2022-09-04hw/openrisc: Add the OpenRISC virtual machineStafford Horne
This patch adds the OpenRISC virtual machine 'virt' for OpenRISC. This platform allows for a convenient CI platform for toolchain, software ports and the OpenRISC linux kernel port. Much of this has been sourced from the m68k and riscv virt platforms. The platform provides: - OpenRISC SMP with up to 4 cpus - A virtio bus with up to 8 devices - Standard ns16550a serial - Goldfish RTC - SiFive TEST device for poweroff and reboot - Generated Device Tree to automatically configure the guest kernel Signed-off-by: Stafford Horne <shorne@gmail.com>

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 Maydell
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.)

2021-09-04hw/acpi: refactor acpi hp modules so that targets can just use what they needAni Sinha
Currently various acpi hotplug modules like cpu hotplug, memory hotplug, pci hotplug, nvdimm hotplug are all pulled in when CONFIG_ACPI_X86 is turned on. This brings in support for whole lot of subsystems that some targets like mips does not need. They are added just to satisfy symbol dependencies. This is ugly and should be avoided. Targets should be able to pull in just what they need and no more. For example, mips only needs support for PIIX4 and does not need acpi pci hotplug support or cpu hotplug support or memory hotplug support etc. This change is an effort to clean this up. In this change, new config variables are added for various acpi hotplug subsystems. Targets like mips can only enable PIIX4 support and not the rest of all the other modules which were being previously pulled in as a part of CONFIG_ACPI_X86. Function stubs make sure that symbols which piix4 needs but are not required by mips (for example, symbols specific to pci hotplug etc) are available to satisfy the dependencies. Currently, this change only addresses issues with mips malta targets. In future we might be able to clean up other targets which are similarly pulling in lot of unnecessary hotplug modules by enabling ACPI_X86. This change should also address issues such as the following: https://gitlab.com/qemu-project/qemu/-/issues/221 https://gitlab.com/qemu-project/qemu/-/issues/193 Signed-off-by: Ani Sinha <ani@anisinha.ca> Message-Id: <20210812071409.492299-1-ani@anisinha.ca> Reviewed-by: Michael S.
