2019-05-13Clean up ill-advised or unusual header guardsMarkus Armbruster1-2/+2
Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. Normalize the exceptions. Done with scripts/clean-header-guards.pl.

2019-03-11hw: Use PFLASH_CFI0{1,2} and TYPE_PFLASH_CFI0{1,2}Markus Armbruster1-2/+2
We have two open-coded copies of macro PFLASH_CFI01(). Move the macro to the header, so we can ditch the copies. Move PFLASH_CFI02() to the header for symmetry. We define macros TYPE_PFLASH_CFI01 and TYPE_PFLASH_CFI02 for type name strings, then mostly use the strings. If the macros are worth defining, they are worth using. Replace the strings by the macros.

2019-03-11pflash: Rename pflash_t to PFlashCFI01, PFlashCFI02Markus Armbruster1-5/+5
flash.h's incomplete struct pflash_t is completed both in pflash_cfi01.c and in pflash_cfi02.c. The complete types are incompatible. This can hide type errors, such as passing a pflash_t created with pflash_cfi02_register() to pflash_cfi01_get_memory(). Furthermore, POSIX reserves typedef names ending with _t. Rename the two structs to PFlashCFI01 and PFlashCFI02.

2019-03-07build: switch to KconfigPaolo Bonzini1-1/+1
The make_device_config.sh script is replaced by minikconf, which is modified to support the same command line as its predecessor. The roots of the parsing are default-configs/*.mak, Kconfig.host and hw/Kconfig. One difference with make_device_config.sh is that all symbols have to be defined in a Kconfig file, including those coming from the configure script. This is the reason for the Kconfig.host file introduced in the previous patch. Whenever a file in default-configs/*.mak used $(...) to refer to a config-host.mak symbol, this is replaced by a Kconfig dependency; this part must be done already in this patch for bisectability.

2019-02-05elf: Add optional function ptr to load_elf() to parse ELF notesLiam Merwick2-5/+9
This patch adds an optional function pointer, 'elf_note_fn', to load_elf() which causes load_elf() to additionally parse any ELF program headers of type PT_NOTE and check to see if the ELF Note is of the type specified by the 'translate_opaque' arg. If a matching ELF Note is found then the specfied function pointer is called to process the ELF note. Passing a NULL function pointer results in ELF Notes being skipped. The first consumer of this functionality is the PVHboot support which needs to read the XEN_ELFNOTE_PHYS32_ENTRY ELF Note while loading the uncompressed kernel binary in order to discover the boot entry address for the x86/HVM direct boot ABI.

Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2017-01-15target/xtensa: refactor CCOUNT/CCOMPAREMax Filippov1-61/+14
Xtensa cores may have a register (CCOUNT) that counts core clock cycles. It may also have a number of registers (CCOMPAREx); when CCOUNT value passes the value of CCOMPAREx, timer interrupt x is raised. Currently xtensa target counts a number of completed instructions and assumes that for CCOUNT one instruction takes one cycle to complete. It calls helper function to update CCOUNT register at every TB end and raise timer interrupts. This scheme works very predictably and doesn't have noticeable performance impact, but it is hard to use with multiple synchronized processors, especially with coming MTTCG. Derive CCOUNT from the virtual simulation time, QEMU_CLOCK_VIRTUAL. Use native QEMU timers for CCOMPARE timers, one timer for each register. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
