c227269e - Stop adding -Wredundant-decls to CWARNFLAGS.

Mon, 07 Feb 2022 20:47:51 +0000

Stop adding -Wredundant-decls to CWARNFLAGS.clang doesn't implement it, and Linux doesn't enforce it. As aresult, new instances keep cropping up both in FreeBSD's code and inupstream sources from vendors.Reviewed by: emasteDifferential Revision: https://reviews.freebsd.org/D34144 List of files: /freebsd-14.2/sys/conf/Makefile.powerpc

1207cda9 - Compile hack.c with normal CFLAGS + -shared -nostdlib.

Sun, 26 Jan 2020 14:19:08 +0000

Compile hack.c with normal CFLAGS + -shared -nostdlib.Originally, hack.c was compiled into a shard object with just -shared-nostdlib. This assumed that ${CC} did not require any additionalflags for ABIs, cross-building, etc.When kern.post.mk was created in r89509 by reducing duplication inkernel Makefile. files, the -shared flag was moved into aHACK_EXTRA_FLAGS variable so that sparc64 could override it with-Wl,-shared. The sparc64 hack was removed in r111650, butHACK_EXTRA_FLAGS was left in place. Over time, we have startedsupport toolchains that require flags to support alternate ABIs onMIPS and PowerPC and started (ab)using HACK_EXTRA_FLAGS to set onlythose flags.I need to fix risc-v to pass -mno-relax to the hack.c build for lld inllvm 10, and the patches to support cross-build from non-FreeBSD hostsneed to include -target for clang in CFLAGS for hack.c. Rather thanadding more hacks into HACK_EXTRA_FLAGS, just use the full set ofCFLAGS with hack.c.Reviewed by: kib, arichardsonMFC after: 1 monthSponsored by: DARPADifferential Revision: https://reviews.freebsd.org/D23362 List of files: /freebsd-14.2/sys/conf/Makefile.powerpc

ab3f2a38 - Add support for building Book-E kernels with clang/lld.

Sat, 02 Nov 2019 21:15:56 +0000

Add support for building Book-E kernels with clang/lld.This involved several changes:* Since lld does not like text relocations, replace SMP boot page text relocsin booke/locore.S with position-independent math, and track the virtual basein the SMP boot page header.* As some SPRs are interpreted differently on clang due to the way it handlesplatform-specific SPRs, switch m*dear and m*esr mnemonics out for regularm*spr. Add both forms of SPR_DEAR to spr.h so the correct encoding is selected.* Change some hardcoded 32 bit things in the boot page to be pointer-sized, andfix alignment.* Fix 64-bit build of booke/pmap.c when enabling pmap debugging.Additionally, I took the opportunity to document how the SMP boot page works.Approved by: jhibbits (mentor)Differential Revision: https://reviews.freebsd.org/D21999 List of files: /freebsd-14.2/sys/conf/Makefile.powerpc

dc9b124d - Create a new MACHINE_ARCH for Freescale PowerPC e500v2

Sat, 22 Oct 2016 01:57:15 +0000

Create a new MACHINE_ARCH for Freescale PowerPC e500v2Summary:The Freescale e500v2 PowerPC core does not use a standard FPU.Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processorunit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with thestock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.Additionaly, the SPE opcodes overlap with Altivec, so these are mutuallyexclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, wascreated with the same function set as in powerpc/powerpc/altivec.c, so itbecomes effectively a drop-in replacement. setjmp/longjmp were modified to savethe upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible bythe SPE).Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does notsupport double-precision floating point.Also, without a new MACHINE_ARCH it would be impossible to provide binarypackages which utilize the SPE.Additionally, no work has been done to support ports, work is needed for this.This also means no newer gcc can yet be used. However, gcc's powerpc supporthas been refactored which would make adding a powerpcspe-freebsd target veryeasy.Test Plan:This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222(P1022-based) board, compiled against the new ABI. Base system utilities(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to bootmultiuser.Reviewed By: bdrewery, impRelnotes: yesDifferential Revision: https://reviews.freebsd.org/D5683 List of files: /freebsd-14.2/sys/conf/Makefile.powerpc

Convert Freescale PowerPC platforms to FDT convention.The following systems are affected: - MPC8555CDS - MPC8572DSThis overhaul covers the following major changes: - All integrated peripherals drivers for Freescale MPC85XX SoC, which are currently in the FreeBSD source tree are reworked and adjusted so they derive config data out of the device tree blob (instead of hard coded / tabelarized values). - This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC, QUICC, UART, CFI. - Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire ocpbus(4) driver, which was based on hard-coded config data.Note that world for these platforms has to be built WITH_FDT.Reviewed by: impSponsored by: The FreeBSD Foundation List of files: /freebsd-14.2/sys/conf/Makefile.powerpc
