The gen_io_end() function is obsolete (as documented in docs/devel/tcg-icount.rst). Where an instruction is an I/O operation, the translator frontend should call gen_io_start() before generating the code which does the I/O, and then end the TB immediately after this insn. Remove the calls to gen_io_end() in the SPARC frontend, and ensure that the insns which were calling it end the TB if they didn't do so already.

2021-05-26cpu: Rename CPUClass vmsd -> legacy_vmsdPhilippe Mathieu-Daudé
Quoting Peter Maydell [*]: There are two ways to handle migration for a CPU object: (1) like any other device, so it has a dc->vmsd that covers migration for the whole object. As usual for objects that are a subclass of a parent that has state, the first entry in the VMStateDescription field list is VMSTATE_CPU(), which migrates the cpu_common fields, followed by whatever the CPU's own migration fields are. (2) a backwards-compatible mechanism for CPUs that were originally migrated using manual "write fields to the migration stream structures". The on-the-wire migration format for those is based on the 'env' pointer (which isn't a QOM object), and the cpu_common part of the migration data is elsewhere. cpu_exec_realizefn() handles both possibilities: * for type 1, dc->vmsd is set and cc->vmsd is not, so cpu_exec_realizefn() does nothing, and the standard "register dc->vmsd for a device" code does everything needed * for type 2, dc->vmsd is NULL and so we register the vmstate_cpu_common directly to handle the cpu-common fields, and the cc->vmsd to handle the per-CPU stuff You can't change a CPU from one type to the other without breaking migration compatibility, which is why some guest architectures are stuck on the cc->vmsd form. New targets should use dc->vmsd. To avoid new targets to start using type (2), rename cc->vmsd as cc->legacy_vmsd. The correct field to implement is dc->vmsd (the DeviceClass one). See also commit b170fce3dd0 ("cpu: Register VMStateDescription through CPUState") for historic background.

2021-05-04hw/sparc*: Move cpu_check_irqs() to target/sparc/Philippe Mathieu-Daudé
Since cpu_check_irqs() doesn't reference to anything outside of CPUSPARCState, it better belongs to the architectural code in target/, rather than the hardware specific code in hw/. Note: while we moved the trace events, we don't rename them. Remark: this allows us to build the leon3 machine stand alone, fixing this link failure (because cpu_check_irqs is defined in hw/sparc/sun4m.c which is only built when CONFIG_SUN4M is selected): /usr/bin/ld: target_sparc_win_helper.c.o: in function `cpu_put_psr': target/sparc/win_helper.c:91: undefined reference to `cpu_check_irqs' Suggested-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20210428141655.387430-5-f4bug@amsat.org> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

Fix by moving the leon3_cache_control_int() / leon3_irq_manager() (which are specific to the leon3 machine) to hw/sparc/leon3.c. Move the trace events along (but don't rename them). leon3_irq_ack() is now locally used, declare it static to reduce its scope.

2021-02-05cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClassClaudio Fontana
we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.

2020-12-19migration: Replace migration's JSON writer by the general oneMarkus Armbruster
Commit 8118f0950f "migration: Append JSON description of migration stream" needs a JSON writer. The existing qobject_to_json() wasn't a good fit, because it requires building a QObject to convert. Instead, migration got its very own JSON writer, in commit 190c882ce2 "QJSON: Add JSON writer". It tacitly limits numbers to int64_t, and strings contents to characters that don't need escaping, unlike qobject_to_json(). The previous commit factored the JSON writer out of qobject_to_json(). Replace migration's JSON writer by it.

2020-12-18linux-user/sparc: Handle tstate in sparc64_get/set_context()Peter Maydell
Correctly implement save/restore of the tstate field in sparc64_get_context() and sparc64_set_context(): * Don't use the CWP value from the guest in set_context * Construct and save a tstate value rather than leaving it as zero in get_context To do this we factor out the "calculate TSTATE value from CPU state" code from sparc_cpu_do_interrupt() into its own sparc64_tstate() function; that in turn requires us to move some of the function prototypes out from inside a CPU_NO_IO_DEFS ifdef guard.

2020-12-18linux-user/sparc: Correct sparc64_get/set_context() FPU handlingPeter Maydell
The handling of the FPU state in sparc64_get_context() and sparc64_set_context() is not the same as what the kernel actually does: we unconditionally read and write the FP registers and the FSR, GSR and FPRS, but the kernel logic is more complicated: * in get_context the kernel has code for saving FPU registers, but it is hidden inside an "if (fenab) condition and the fenab flag is always set to 0 (inside an "#if 1" which has been in the kernel for over 15 years). So the effect is that the FPU state part is always written as zeroes. * in set_context the kernel looks at the fenab field in the structure from the guest, and only restores the state if it is set; it also looks at the structure's FPRS to see whether either the upper or lower or both halves of the register file have valid data. Bring our implementations into line with the kernel: * in get_context: - clear the entire target_ucontext at the top of the function (as the kernel does) - then don't write the FPU state, so those fields remain zero - this fixes Coverity issue CID 1432305 by deleting the code it was complaining about * in set_context: - check the fenab and the fpsr to decide which parts of the FPU data to restore, if any - instead of setting the FPU registers by doing two 32-bit loads and filling in the .upper and .lower parts of the CPU_Double union separately, just do a 64-bit load of the whole register at once. This fixes Coverity issue CID 1432303 because we now access the dregs[] part of the mcfpu_fregs union rather than the sregs[] part (which is not large enough to actually cover the whole of the data, so we were accessing off the end of sregs[]) We change both functions in a single commit to avoid potentially breaking bisection.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-07-10error: Eliminate error_propagate() with Coccinelle, part 1Markus Armbruster
When all we do with an Error we receive into a local variable is propagating to somewhere else, we can just as well receive it there right away. Convert if (!foo(..., &err)) { ... error_propagate(errp, err); ... return ... } to if (!foo(..., errp)) { ... ... return ... } where nothing else needs @err. Coccinelle script: @rule1 forall@ identifier fun, err, errp, lbl; expression list args, args2; binary operator op; constant c1, c2; symbol false; @@ if ( ( - fun(args, &err, args2) + fun(args, errp, args2) | - !fun(args, &err, args2) + !fun(args, errp, args2) | - fun(args, &err, args2) op c1 + fun(args, errp, args2) op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; ) } @rule2 forall@ identifier fun, err, errp, lbl; expression list args, args2; expression var; binary operator op; constant c1, c2; symbol false; @@ - var = fun(args, &err, args2); + var = fun(args, errp, args2); ... when != err if ( ( var | !var | var op c1 ) ) { ... when != err when != lbl: when strict - error_propagate(errp, err); ... when != err ( return; | return c2; | return false; | return var; ) } @depends on rule1 || rule2@ identifier err; @@ - Error *err = NULL; ... when != err Not exactly elegant, I'm afraid. The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually. One nested declaration of @local_err deleted manually. Preexisting unwanted blank line dropped in hw/riscv/sifive_e.c.
