2020-05-26MAINTAINERS: Add Huacai Chen as fuloong2e co-maintainerHuacai Chen
I submitted the MIPS/fuloong2e support about ten years ago, and after that I became a MIPS kernel developer. Last year, Philippe Mathieu- Daudé asked me that whether I can be a reviewer of MIPS/fuloong2e, and I promised that I will do some QEMU work in the next year (i.e., 2020 and later). I think now (and also in future) I can have some spare time, so I can finally do some real work on QEMU/MIPS. And if possible, I hope I can be a co-maintainer of MIPS/fuloong2e.

2020-05-26audio/mixeng: fix clang 10+ warningVolker Rümelin
The code in CONV_NATURAL_FLOAT() and CLIP_NATURAL_FLOAT() seems to use the constant 2^31-0.5 to convert float to integer and back. But the float type lacks the required precision and the constant used for the conversion is 2^31. This is equiva- lent to a [-1.f, 1.f] <-> [INT32_MIN, INT32_MAX + 1] mapping. This patch explicitly writes down the used constant. The compiler generated code doesn't change. The constant 2^31 has an exact float representation and the clang 10 compiler stops complaining about an implicit int to float conversion with a changed value. A few notes: - The conversion of 1.f to INT32_MAX + 1 doesn't overflow. The type of the destination variable is int64_t. - At a later stage one of the clip_* functions in audio/mixeng_template.h limits INT32_MAX + 1 to the integer range. - The clip_natural_float_* functions in audio/mixeng.c convert INT32_MAX and INT32_MAX + 1 to 1.f.

2020-05-22hw/block/pflash_cfi01: Document use of non-CFI compliant command '0x00'Philippe Mathieu-Daudé
The command 0x00 is used by this model since its origin (commit 05ee37ebf630). In this commit the command is described with a amusing '/* ??? */' comment, probably meaning 'FIXME'. switch (cmd) { case 0x00: /* ??? */ ... This comment survived 12 years because the 0x00 value is indeed not specified by the CFI open standard (as of this commit). The 'cmd' field is transfered during migration. To keep the migration feature working with older QEMU version, we have to take a lot of care with migrated field. We figured out it is too late to remove a non-specified value from this model (this would make migration review very complex). It is however not too late to improve the documentation. Add few comments to remember this is a special value related to QEMU, and we won't find information about it on the CFI spec.

2020-05-21linux-user/arm/signal.c: Drop TARGET_CONFIG_CPU_32Peter Maydell
The Arm signal-handling code has some parts ifdeffed with a TARGET_CONFIG_CPU_32, which is always defined. This is a leftover from when this code's structure was based on the Linux kernel signal handling code, where it was intended to support 26-bit Arm CPUs. The kernel dropped its CONFIG_CPU_32 in kernel commit 4da8b8208eded0ba21e3 in 2009. QEMU has never had 26-bit CPU support and is unlikely to ever add it; we certainly aren't going to support 26-bit Linux binaries via linux-user mode. The ifdef is just unhelpful noise, so remove it entirely.

2020-05-21target/arm: Allow user-mode code to write CPSR.E via MSRPeter Maydell
Using the MSR instruction to write to CPSR.E is deprecated, but it is required to work from any mode including unprivileged code. We were incorrectly forbidding usermode code from writing it because CPSR_USER did not include the CPSR_E bit. We use CPSR_USER in only three places: * as the mask of what to allow userspace MSR to write to CPSR * when deciding what bits a linux-user signal-return should be able to write from the sigcontext structure * in target_user_copy_regs() when we set up the initial registers for the linux-user process In the first two cases not being able to update CPSR.E is a bug, and in the third case it doesn't matter because CPSR.E is always 0 there. So we can fix both bugs by adding CPSR_E to CPSR_USER. Because the cpsr_write() in restore_sigcontext() is now changing a CPSR bit which is cached in hflags, we need to add an arm_rebuild_hflags() call there; the callsite in target_user_copy_regs() was already rebuilding hflags for other reasons. (The recommended way to change CPSR.E is to use the 'SETEND' instruction, which we do correctly allow from usermode code.)

hw_error() calls exit(). This a bit overkill when we can log the accesses as unimplemented or guest error. When fuzzing the devices, we don't want the whole process to exit. Replace some hw_error() calls by qemu_log_mask(). Per the datasheet "Exynos 4412 RISC Microprocessor Rev 1.00" Chapter 25 "Multi Core Timer (MCT)" figure 1 and table 4, the default value on the APB bus is 0.

2020-05-21linux-user/arm: Fix identification of syscall numbersPeter Maydell
Our code to identify syscall numbers has some issues: * for Thumb mode, we never need the immediate value from the insn, but we always read it anyway * bad immediate values in the svc insn should cause a SIGILL, but we were abort()ing instead (via "goto error") We can fix both these things by refactoring the code that identifies the syscall number to more closely follow the kernel COMPAT_OABI code: * for Thumb it is always r7 * for Arm, if the immediate value is 0, then this is an EABI call with the syscall number in r7 * otherwise, we XOR the immediate value with 0x900000 (ARM_SYSCALL_BASE for QEMU; __NR_OABI_SYSCALL_BASE in the kernel), which converts valid syscall immediates into the desired value, and puts all invalid immediates in the range 0x100000 or above * then we can just let the existing "value too large, deliver SIGILL" case handle invalid numbers, and drop the 'goto error' Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.
