2020-10-17target/mips: Move cpu_mips_get_random() with CP0 helpersPhilippe Mathieu-Daudé3-26/+26
The get_random() helper uses the CP0_Wired register, which is unrelated to the CP0_Count register used as timer. Commit e16fe40c872 ("Move the MIPS CPU timer in a separate file") incorrectly moved this get_random() helper with timer specific code. Move it back to generic CP0 helpers.

2020-10-17target/mips/op_helper: Convert multiple if() to switch casePhilippe Mathieu-Daudé1-4/+9
The cache operation is encoded in bits [20:18] of the instruction. The 'op' argument of helper_cache() contains the bits [20:16]. Extract the 3 bits and parse them using a switch case. This allow us to handle multiple cache types (the cache type is encoded in bits [17:16]). Previously the if() block was only checking the D-Cache (Primary Data or Unified Primary). Now we also handle the I-Cache (Primary Instruction), S-Cache (Secondary) and T-Cache (Terciary).

2020-10-15block: deprecate the sheepdog block driverDaniel P. Berrangé3-2/+26
This thread from a little over a year ago: http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html states that sheepdog is no longer actively developed. The only mentioned users are some companies who are said to have it for legacy reasons with plans to replace it by Ceph. There is talk about cutting out existing features to turn it into a simple demo of how to write a distributed block service. There is no evidence of anyone working on that idea: https://github.com/sheepdog/sheepdog/commits/master No real commits to git since Jan 2018, and before then just some minor technical debt cleanup. There is essentially no activity on the mailing list aside from patches to QEMU that get CC'd due to our MAINTAINERS entry. Fedora packages for sheepdog failed to build from upstream source because of the more strict linker that no longer merges duplicate global symbols. Fedora patches it to add the missing "extern" annotations and presumably other distros do to, but upstream source remains broken. There is only basic compile testing, no functional testing of the driver. Since there are no build pre-requisites the sheepdog driver is currently enabled unconditionally. This would result in configure issuing a deprecation warning by default for all users. Thus the configure default is changed to disable it, requiring users to pass --enable-sheepdog to build the driver.

The sheepdog mailing list is setup to stop and queue messages from non-subscribers, pending moderator approval. Unfortunately it seems that the moderation queue is not actively dealt with. Even when messages are approved, the sender is never added to the whitelist, so every future mail from the same sender continues to get stopped for moderation. MAINTAINERS entries should be responsive and not unneccessarily block mails from QEMU contributors, so drop the sheepdog mailing list.

2020-10-15keyval: Parse help optionsKevin Wolf6-78/+185
This adds a special meaning for 'help' and '?' as options to the keyval parser. Instead of being an error (because of a missing value) or a value for an implied key, they now request help, which is a new boolean output of the parser in addition to the QDict. A new parameter 'p_help' is added to keyval_parse() that contains on return whether help was requested. If NULL is passed, requesting help results in an error and all other cases work like before. Turning previous error cases into help is a compatible extension. The behaviour potentially changes for implied keys: They could previously get 'help' as their value, which is now interpreted as requesting help. This is not a problem in practice because 'help' and '?' are not a valid values for the implied key of any option parsed with keyval_parse(): * audiodev: union Audiodev, implied key "driver" is enum AudiodevDriver, "help" and "?" are not among its values * display: union DisplayOptions, implied key "type" is enum DisplayType, "help" and "?" are not among its values * blockdev: union BlockdevOptions, implied key "driver is enum BlockdevDriver, "help" and "?" are not among its values * export: union BlockExport, implied key "type" is enum BlockExportType, "help" and "?" are not among its values * monitor: struct MonitorOptions, implied key "mode" is enum MonitorMode, "help" and "?" are not among its values * nbd-server: struct NbdServerOptions, no implied key.

2020-10-15module: silence errors for module_load_qom_all().Gerd Hoffmann3-15/+15
Add mayfail bool parameter to module loading functions. Set it to true for module_load_qom_all() because device modules might not load into all system emulation variants. qemu-system-s390x for example will not load qxl because it lacks vga support. Makes "make check" less chatty. Drop module_loaded_qom_all check in module_load_qom_one to make sure we see errors for explicit load requests, i.e. module_load_qom_one("qxl") failing will log an error no matter whenever module_load_qom_all() was called before or not.

2020-10-14win32: Simplify gmtime_r detection not depends on if _POSIX_C_SOURCE are ↵Yonggang Luo3-38/+4
defined on msys2/mingw We remove the CONFIG_LOCALTIME_R detection option in configure, and move the check existence of gmtime_r from configure into C header and source directly by using macro `_POSIX_THREAD_SAFE_FUNCTIONS`. Before this patch, the configure script are always assume the compiler doesn't define _POSIX_C_SOURCE macro at all, but that's not true, because thirdparty library such as ncursesw may define -D_POSIX_C_SOURCE in it's pkg-config file. And that C Flags will added -D_POSIX_C_SOURCE into each QEMU_CFLAGS. And that's causing the following compiling error: n file included from C:/work/xemu/qemu/include/qemu/osdep.h:119, from ../softmmu/main.c:25: C:/work/xemu/qemu/include/sysemu/os-win32.h:53:12: error: redundant redeclaration of 'gmtime_r' [-Werror=redundant-decls] 53 | struct tm *gmtime_r(const time_t *timep, struct tm *result); | ^~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:94, from ../softmmu/main.c:25: C:/CI-Tools/msys64/mingw64/x86_64-w64-mingw32/include/time.h:284:36: note: previous definition of 'gmtime_r' was here 284 | __forceinline struct tm *__CRTDECL gmtime_r(const time_t *_Time, struct tm *_Tm) { | ^~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:119, from ../softmmu/main.c:25: C:/work/xemu/qemu/include/sysemu/os-win32.h:55:12: error: redundant redeclaration of 'localtime_r' [-Werror=redundant-decls] 55 | struct tm *localtime_r(const time_t *timep, struct tm *result); | ^~~~~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:94, from ../softmmu/main.c:25: C:/CI-Tools/msys64/mingw64/x86_64-w64-mingw32/include/time.h:281:36: note: previous definition of 'localtime_r' was here 281 | __forceinline struct tm *__CRTDECL localtime_r(const time_t *_Time, struct tm *_Tm) { | ^~~~~~~~~~~ Compiling C object libcommon.fa.p/hw_gpio_zaurus.c.obj In file included from C:/work/xemu/qemu/include/qemu/osdep.h:119, from ../hw/i2c/smbus_slave.c:16: C:/work/xemu/qemu/include/sysemu/os-win32.h:53:12: error: redundant redeclaration of 'gmtime_r' [-Werror=redundant-decls] 53 | struct tm *gmtime_r(const time_t *timep, struct tm *result); | ^~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:94, from ../hw/i2c/smbus_slave.c:16: C:/CI-Tools/msys64/mingw64/x86_64-w64-mingw32/include/time.h:284:36: note: previous definition of 'gmtime_r' was here 284 | __forceinline struct tm *__CRTDECL gmtime_r(const time_t *_Time, struct tm *_Tm) { | ^~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:119, from ../hw/i2c/smbus_slave.c:16: C:/work/xemu/qemu/include/sysemu/os-win32.h:55:12: error: redundant redeclaration of 'localtime_r' [-Werror=redundant-decls] 55 | struct tm *localtime_r(const time_t *timep, struct tm *result); | ^~~~~~~~~~~ In file included from C:/work/xemu/qemu/include/qemu/osdep.h:94, from ../hw/i2c/smbus_slave.c:16: C:/CI-Tools/msys64/mingw64/x86_64-w64-mingw32/include/time.h:281:36: note: previous definition of 'localtime_r' was here 281 | __forceinline struct tm *__CRTDECL localtime_r(const time_t *_Time, struct tm *_Tm) { | ^~~~~~~~~~~ Compiling C object libcommon.fa.p/hw_dma_xilinx_axidma.c.obj After this patch, whenever ncursesw or other thirdparty libraries tried to define or not define _POSIX_C_SOURCE, the source will building properly.
