kernel: Add defination of .init_array and .fini_array for all other platformsCurrently these sections are not used but defined only for amd64 andi386. Added them for all other platforms to keep all platforms in sync.There should be no functional change.This change is extracted from a bigger patch [1] of hselasky, withadditional fix for the order of .fini_array section.1. https://reviews.freebsd.org/D40467Obtained from: hselaskyMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D45214 List of files: /freebsd/sys/conf/ldscript.powerpc64

kernel: Move the debug stuff into a common scriptMove a copy of amd64's debug code into debug.ldscript. Make all thekernels use this. This has the effect of modernizing the STABS forpowerpc as the others were almost already in sync. For the ones thatweren't this adds the DWARF 3 debug symbols from i386/amd64.Sponsored by: NetflixDifferential Revision: https://reviews.freebsd.org/D44071 List of files: /freebsd/sys/conf/ldscript.powerpc64

Fri, 26 Jan 2024 01:19:02 +0100

ldscript.powerpc*: Only put .dynamic in PT_DYNAMICCurrently there are a few output sections left as implicitly using:kernel :dynamic before :kernel on its own is used again, which meansthey end up in both the PT_LOAD and the PT_DYNAMIC segments, an unusualsituation which the new libelf-based kldxref initially treated asinvalid. Thus, hoist the :kernel to the very next section to ensure only.dynamic is in PT_DYNAMIC, as is more normal.Whilst here, sync ldscript.powerpc64le with ldscript.powerpc64 to pickup various fixes that were presumably made between the start of thepowerpc64le port and it being committed and got missed.Reviewed by: jhibbits, jhbDifferential Revision: https://reviews.freebsd.org/D43066 List of files: /freebsd/sys/conf/ldscript.powerpc64

Thu, 07 May 2020 21:32:49 +0200

[PowerPC] kernel ifunc support for powerpc*, fix ppc64 relocation oddities.This is a general cleanup of the relocatable kernel support on powerpc,needed to enable kernel ifuncs. * Fix some relocatable issues in the kernel linker, and change to using a RELOCATABLE_KERNEL #define instead of #ifdef __powerpc__ for parts that other platforms can use in the future if they wish to have ET_DYN kernels. * Get rid of the DB_STOFFS hack now that the kernel is relocated to the DMAP properly across the board on powerpc64. * Add powerpc64 and powerpc32 ifunc functionality. * Allow AIM64 virtual mode OF kernels to run from the DMAP like other AIM64 by implementing a virtual mode restart. This fixes the runtime address on PowerMac G5. * Fix symbol relocation problems on post-relocation kernels by relocating the symbol table. * Add an undocumented method for supplying kernel symbols on powernv and other powerpc machines using linux-style kernel/initrd loading -- If you pass the kernel in as the initrd as well, the copy resident in initrd will be used as a source for symbols when initializing the debugger. This method is subject to removal once we have a better way of doing this.Approved by: jhibbitsRelnotes: yesSponsored by: Tag1 Consulting, Inc.Differential Revision: https://reviews.freebsd.org/D23156 List of files: /freebsd/sys/conf/ldscript.powerpc64

Fri, 29 Dec 2017 21:30:10 +0100

Add support for 64-bit PowerPC kernels to be directly loaded by kexec, whichis used as the bootloader on a number of PPC64 platforms. This involves thefollowing pieces:- Making the first instruction a valid kernel entry point, since kexec ignores the ELF entry value. This requires a separate section and linker magic to prevent the linker from filling the beginning of the section with stubs.- Adding an entry point at 0x60 past the first instruction for systems lacking firmware CPU shutdown support (notably PS3).- Linker script changes to support the above.MFC after: 1 month List of files: /freebsd/sys/conf/ldscript.powerpc64
