2020-03-17cpu: Use DeviceClass reset instead of a special CPUClass resetPeter Maydell2-5/+5
The CPUClass has a 'reset' method. This is a legacy from when TYPE_CPU used not to inherit from TYPE_DEVICE. We don't need it any more, as we can simply use the TYPE_DEVICE reset. The 'cpu_reset()' function is kept as the API which most places use to reset a CPU; it is now a wrapper which calls device_cold_reset() and then the tracepoint function. This change should not cause CPU objects to be reset more often than they are at the moment, because: * nobody is directly calling device_cold_reset() or qdev_reset_all() on CPU objects * no CPU object is on a qbus, so they will not be reset either by somebody calling qbus_reset_all()/bus_cold_reset(), or by the main "reset sysbus and everything in the qbus tree" reset that most devices are reset by Note that this does not change the need for each machine or whatever to use qemu_register_reset() to arrange to call cpu_reset() -- that is necessary because CPU objects are not on any qbus, so they don't get reset when the qbus tree rooted at the sysbus bus is reset, and this isn't being changed here. All the changes to the files under target/ were made using the included Coccinelle script, except: (1) the deletion of the now-inaccurate and not terribly useful "CPUClass::reset" comments was done with a perl one-liner afterwards: perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c (2) this bit of the s390 change was done by hand, because the Coccinelle script is not sophisticated enough to handle the parent_reset call being inside another function: | @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type) | S390CPU *cpu = S390_CPU(s); | S390CPUClass *scc = S390_CPU_GET_CLASS(cpu); | CPUS390XState *env = &cpu->env; |+ DeviceState *dev = DEVICE(s); | |- scc->parent_reset(s); |+ scc->parent_reset(dev); | cpu->env.sigp_order = 0; | s390_cpu_set_state(S390_CPU_STATE_STOPPED, cpu); Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200303100511.5498-1-peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

The mask used when setting FPCSR allows setting bits 10 to 1. However, OpenRISC has flags and config bits in 11 to 1, 11 being Divide by Zero Flag (DZF). This seems like an off-by-one bug.

CPUClass method dump_statistics() takes an fprintf()-like callback and a FILE * to pass to it. Most callers pass fprintf() and stderr. log_cpu_state() passes fprintf() and qemu_log_file. hmp_info_registers() passes monitor_fprintf() and the current monitor cast to FILE *. monitor_fprintf() casts it right back, and is otherwise identical to monitor_printf(). The callback gets passed around a lot, which is tiresome. The type-punning around monitor_fprintf() is ugly. Drop the callback, and call qemu_fprintf() instead. Also gets rid of the type-punning, since qemu_fprintf() takes NULL instead of the current monitor cast to FILE *.

2019-04-18target: Simplify how the TARGET_cpu_list() printMarkus Armbruster2-11/+6
The various TARGET_cpu_list() take an fprintf()-like callback and a FILE * to pass to it. Their callers (vl.c's main() via list_cpus(), bsd-user/main.c's main(), linux-user/main.c's main()) all pass fprintf() and stdout. Thus, the flexibility provided by the (rather tiresome) indirection isn't actually used. Drop the callback, and call qemu_printf() instead. Calling printf() would also work, but would make the code unsuitable for monitor context without making it simpler.

2019-01-30target/openrisc: Fix LGPL version numberThomas Huth7-7/+7
It's either "GNU *Library* General Public version 2" or "GNU Lesser General Public version *2.1*", but there was no "version 2.0" of the "Lesser" library. So assume that version 2.1 is meant here.

2018-10-31decodetree: Remove "insn" argument from trans_* expandersRichard Henderson2-112/+111
This allows trans_* expanders to be shared between decoders for 32 and 16-bit insns, by not tying the expander to the size of the insn that produced it. This change requires adjusting the two existing users to match.

2018-07-03target/openrisc: Fix writes to interrupt mask registerStafford Horne1-1/+1
The interrupt controller mask register (PICMR) allows writing any value to any of the 32 interrupt mask bits. Writing a 0 masks the interrupt writing a 1 unmasks (enables) the the interrupt. For some reason the old code was or'ing the write values to the PICMR meaning it was not possible to ever mask a interrupt once it was enabled. I have tested this by running linux 4.18 and my regular checks, I don't see any issues.

2018-07-03target/openrisc: Fix delay slot exception flag to match specStafford Horne1-7/+12
The delay slot exception flag is only set on the SR register during exception. Previously it was being set on both the ESR and SR this caused QEMU to differ from the spec. The was apparent as the linux kernel had a bug where it could boot on QEMU but not on real hardware. The fixed logic now matches hardware.
