* build: fix recurse-all targetPaolo Bonzini2020-09-011-7/+3Star
| | | | | | | | | | | | | | | The missing "/all" suffix prevents the pc-bios/ parts of the build from running. In the meanwhile, -Wall has moved from QEMU_CFLAGS to CFLAGS. Simplify everything by not passing down CFLAGS, and add -Wall in the recursive Makefiles.

* optionrom: add new PVH option romStefano Garzarella2019-02-051-1/+4
| | | | | | | | | | | | | | | | | | The new pvh.bin option rom can be used with SeaBIOS to boot uncompressed kernel using the x86/HVM direct boot ABI. pvh.S contains the entry point of the option rom. It runs in real mode, loads the e820 table querying the BIOS, and then it switches to 32bit protected mode and jumps to the pvh_load_kernel() written in pvh_main.c. pvh_load_kernel() loads the cmdline and kernel entry_point using fw_cfg, then it looks for RSDP, fills the hvm_start_info required by x86/HVM ABI, and finally jumps to the kernel entry_point.

* rules.mak: quiet-command: Split command name and args to printPeter Maydell2016-10-061-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

* pc-bios/optionrom: Fix OpenBSD build with better detection of linker emulationPeter Maydell2016-08-151-11/+1Star
| | | | | | | | | | | | | | | | | | | The various host OSes are irritatingly variable about the name of the linker emulation we need to pass to ld's -m option to build the i386 option ROMs. Instead of doing this via a CONFIG ifdef, check in configure whether any of the emulation names we know about will work and pass the right answer through to the makefile. If we can't find one, we fall back to not trying to build the option ROMs, in the same way we would for a non-x86 host platform. This is in particular necessary to unbreak the build on OpenBSD, since it wants a different answer to FreeBSD and we don't have an existing CONFIG_ variable that distinguishes the two.

* optionrom: fix compilation with mingw docker targetPaolo Bonzini2016-08-091-1/+9
| | | | | | | | | | | | | | | | | | | | Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE, hence --enable-debug disables optimization. This is not acceptable for ROMs, which should override CFLAGS to force inclusion of -O2. Second, PE stores global constructors and destructors using the following linker script snippet: ___CTOR_LIST__ = .; __CTOR_LIST__ = . ; LONG (-1);*(.ctors); *(.ctor); *(SORT(.ctors.*)); LONG (0); ___DTOR_LIST__ = .; __DTOR_LIST__ = . ; LONG (-1); *(.dtors); *(.dtor); *(SORT(.dtors.*)); LONG (0); The LONG directives cause the .img files to be 16 bytes too large; the recently added check to signrom.py catches this. To fix this, replace -T and -e options with a linker script. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* build-sys: fix building with make CFLAGS=.. argumentMarc-André Lureau2016-08-091-2/+0Star
| | | | | | | | | | | | | | | | When calling make with a CFLAGS=.. argument, the -g/-O filter is not applied, which may result with build failure with ASAN for example. It could be solved with an 'override' directive on CFLAGS, but that would actually prevent setting different CFLAGS manually. Instead, filter the CFLAGS argument from the top-level Makefile (so you could still call make with a different CFLAGS argument on a rom/Makefile manually) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20160805082421.21994-2-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* optionrom: fix detection of -Wa,-32Paolo Bonzini2016-07-291-1/+1
| | | | | | | | | | | | | The cc-option macro runs $(CC) in -S mode (generate assembly) to avoid a pointless run of the assembler. However, this does not work when you want to detect support for cc->as option passthrough. clang ignores -Wa unless -c is provided, and exits successfully even if the -Wa,-32 option is not supported.

* Fix QEMU build on OpenBSD on x86 archsBrad2014-02-171-1/+2
| | | | | | | | | | | | | | | | | This resolves the build issue with building the ROMs on OpenBSD on x86 archs. As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the whole OS/packages and so forth. The ROMs need to have PIE disabled. Check in configure whether the compiler supports the flags for disabling PIE, and if it does then use them for building the ROMs. This fixes the following buildbot failure: >From the OpenBSD buildbots..

Since "vpath %.c %.h PATH" is not valid, I'm introducing a wrapper macro to append one or more directories to the vpath.
