Enrico Weigelt, metux IT consult	33b79c397c	include: compiler.h: ppc64el eieio barrier fallback for GCC 12.2 ... __builtin_ppc_eieio() is not available on ppc64le (little-endian) with GCC 12.2 ("implicit declaration of function '__builtin_ppc_eieio'"), breaking the CI native build lanes for ppc64el. Use an asm("eieio") fallback on ppc64 (and whenever __has_builtin cannot confirm the builtin), and route the xf86WriteMmio* barriers through write_mem_barrier() so there is a single arch-correct place. Validated: powerpc64le-linux-gnu-gcc-12 -fsyntax-only passes with the fix and fails with "implicit declaration" without it.

Enrico Weigelt, metux IT consult	cd3fb8ba8e	include: compiler.h: switch ioBase to void * ... ioBase is an opaque mmap() result; nothing in-tree dereferences it or does pointer arithmetic on it — all MMIO access goes through the xf86Read/WriteMmio* helpers. Making it void *: - removes the discarded-qualifiers warnings at the munmap() call sites in lnx_video.c and ppc_video.c - drops the now-redundant (void *) casts in the inb/outb wrappers in compiler.h - fixes the BSD/ppc munmap path that referenced the (undefined) __DEVOLATILE/__UNVOLATILE macros ABI-neutral: the exported data symbol keeps its size and address.

Not it's a good time for getting rid of that indirection within the header. The wrappers are still available for driver compat.

Enrico Weigelt, metux IT consult	d497b720fb	include: compiler.h: restore MIPS port I/O port access (12-year-old bug) ... With commit b5141a1fab (2014-07-22, "xfree86: Simplify a bunch of OS and arch conditionals"), the MIPS port I/O and MMIO code has been incorrectly nested inside the `#elif defined(__arm32__) && !defined(__linux__)` - thus impossible to ever become active. Ergo: MIPS support was broken all the time, Xservers compiled on MIPS lacked basic IO support.

Enrico Weigelt, metux IT consult	3e7faaf43a	sparc: rename ASI_PL to __XLIBRE_SPARC_ASI_PRIMAY_LE ... This define may also be set by (OS specific) system headers on Sparc machines and just holds the adress space identifier bitmask for accessing in PRIMARY address space (normal userspace) with automatic LE conversion. The value physically constant, defined by the instruction set itself, thus no need to rely on external headers at all. In order to prevent header possible conflicts, make a private and temporary #define here. Note: we could just write the 0x88 here, but for readability, let's leave a define with some actually telling name in here.

Enrico Weigelt, metux IT consult	7b814e62c4	include: compiler.h: replace alpha MMIO_(IN|OUT)* by inline functions ... These macros currently doing nothing else than mapping to the corresponding (alpha-specific) xf86(Read|Write)Mmio* inline functions. And those aren't referenced directly by any drivers, neither are they actual symbols (since they're inlined). Thus, let's lighten the wood a bit by just renaming those functions to MMIO_(IN|OUT)* and drop the extra macros.

Enrico Weigelt, metux IT consult	8bf1079f25	include: compiler.h: use <sys/mman.h> instead of MAP_FAILED fallback in powerpc branch ... MAP_FAILED is POSIX-mandated and provided by <sys/mman.h> on every powerpc platform the server builds on (Linux, the BSDs, Darwin). The hand-rolled #ifndef MAP_FAILED fallback dates back to XFree86 4.3 and only exists to support antique C libraries; drop it and take the authoritative system definition instead. The include is scoped to the powerpc branch, the only branch whose in/out accessors compare ioBase against MAP_FAILED.

Enrico Weigelt, metux IT consult	ed3befc01a	include: compiler.h: drop noop for barrier(), mem_barrier(), write_mem_barrier() ... These are fallback definitions for the case we're on some platform that doesn't have them defined above. While it seens comfortable to do so, it has the big drawback that we don't see if some platform is missing here. Therefore, drop them, so we'll actually see FTBS on unsupported platform and then implement the necessary pieces.

These pieces of experimental support in here came from some PoC done by the silicon vendor (Andes Technology), which never actually made it into production.

Enrico Weigelt, metux IT consult	e9b532fd12	compiler.h: replace legacy __inline__/__inline with standard C99 inline ... __inline__ and __inline are GCC legacy keywords. The X server already requires C99 (inline is a standard keyword). Every supported compiler (GCC, Clang) defines __GNUC__ which guarantees built-in support for inline, so the fallback blocks in compiler.h are redundant. Replace all uses of static __inline__ with static inline in: - include/compiler.h (80+ occurrences in arch port I/O/MMIO) - hw/xfree86/int10/generic.c - hw/xfree86/x86emu/sys.c - hw/xquartz/xpr/x-hash.h Remove the #ifndef __inline__ / __inline fallback blocks entirely.
