* linux-user/riscv: Implement setup_sigtrampRichard Henderson2021-10-012-9/+15
| | | | | | | | | | | | | | | | Create and record the rt signal trampoline. This fixes a bug wrt libgcc fallback unwinding. It expects the stack pointer to point to the siginfo_t, whereas we had inexplicably placed our private signal trampoline at the start of the signal frame instead of the end. Now moot because we have removed it from the stack frame entirely.

The reason is that the state of m25p80 loops in STATE_READING_DATA state after receiving RDSR command, the new command is ignored. Before sending a new command, CS line should be pulled high to make the state of m25p80 back to IDLE. Currently the SPI flash CS line is connected to the SPI controller, but on the real board, it's connected to GPIO3_19. This matches the ecspi1 device node in the board dts. ecspi1 node in imx6qdl-sabrelite.dtsi: &ecspi1 { cs-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi1>; status = "okay"; flash: m25p80@0 { compatible = "sst,sst25vf016b", "jedec,spi-nor"; spi-max-frequency = <20000000>; reg = <0>; }; }; Should connect the SSI_GPIO_CS to GPIO3_19 when adding a spi-nor to spi1 on sabrelite machine.

Almost all callers want to use the autogenerated name; the only exception is the virtio-scsi device. Taking a name argument that should almost always be NULL is an easy-to-misuse API design -- it encourages callers to think perhaps they should pass in some standard name like "scsi" or "scsi-bus". We don't do this anywhere for SCSI, but we do (incorrectly) do it for other bus types such as i2c. The function name also implies that it will return a newly allocated object, when it in fact does in-place allocation. We more commonly name such functions foo_init(), with foo_new() being the allocate-and-return variant. Replace all the scsi_bus_new() callsites with either: * scsi_bus_init() for the usual case where the caller wants an autogenerated bus name * scsi_bus_init_named() for the rare case where the caller needs to specify the bus name and document that for the _named() version it's then the caller's responsibility to think about uniqueness of bus names.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Allwinner H3 SoC uses Cortex-A7 cores which support virtualization. However, today we are configuring QEMU to use HVC as PSCI conduit. That means HVC calls get trapped into QEMU instead of the guest's own emulated CPU and thus break the guest's ability to execute virtualization. Fix this by moving to SMC as conduit, freeing up HYP completely to the VM.
