Make ISA_206_ATOMICS a kernel optionSummary:To make it easier to build a kernel with PowerISA 2.06 atomics (sub-wordatomics), add a kernel config option. User space still needs to specifyit as a CFLAG but that seems easier to do than for the kernel config.Reviewed By: luporlDifferential Revision: https://reviews.freebsd.org/D29809 List of files: /freebsd/sys/conf/options.powerpc

4efb1ca7d2a44cfb33d7f9e18bd92f8d68dcfee0 - [PowerPC64LE] Work around qemu TCG bug in mtmsrd emulation.

Wed, 23 Sep 2020 02:09:29 +0200

[PowerPC64LE] Work around qemu TCG bug in mtmsrd emulation.The TCG implementation of mtmsrd in qemu blindly copies the entire registerto the MSR, instead of the specific bit positions listed in the ISA.This means that qemu will prematurely switch endian out from under therunning code instead of waiting for the rfid, causing an immediate trapas it attempts to interpret the next instruction in the wrong endianness.To work around this, ensure PSL_LE is still set before doing the mtmsrd.In the future, we may wish to just turn off translation and unconditionallyuse rfid to switch to the ofmsr instead of quasi-switching to the ofmsr.Add a new platform option so this can be disabled. (And so that we canconditonalize additional QEMU-specific hacks in the platform code.)Sponsored by: Tag1 Consulting, Inc. List of files: /freebsd/sys/conf/options.powerpc

powerpc: Add AmigaOne platform, a subclass of MPC85xxSummary:The AmigaOne platform, encompassing the X5000 and A1222 at this time, isbased on the mpc85xx platform, but includes some things not listed inthe device tree. Some custom devices, like CPLD, could be added to thedevice tree with an overlay, or other means. However, some cannoteasily be done, such as the power button interrupt.The directory will also become a location to add AmigaOne platform drivers,such as the aforementioned CPLD, and its children.Reviewed by: bdragonDifferential Revision: https://reviews.freebsd.org/D21829 List of files: /freebsd/sys/conf/options.powerpc

In-progress networkdriver compabibility improvements may add over 100 more so this iscloser to "just about everywhere" than "only some files" per theguidance in sys/conf/options.Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset ofsys/compat/linux/*.c.

dc9b124d6668d984b8a012e21fef6a0fe585faef - Create a new MACHINE_ARCH for Freescale PowerPC e500v2

Sat, 22 Oct 2016 03:57:15 +0200

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/sys/conf/options.powerpc

6cedae09a2b2886bf937499423bba35ea1196438 - Merge MPC85XX and QorIQ config options

Wed, 03 Aug 2016 03:22:11 +0200

Merge MPC85XX and QorIQ config optionsSummary:MPC85XX and QorIQ are very similar. When the DPAA dTSEC driver wasadded, QORIQ_DPAA was brought in as a config option to support the differencesin hardware register settings between QorIQ (e500mc-, e5500- based) SoCs andQUICC (e500v1/e500v2-based) SoCs, particularly in the Local Access Window (LAW)target settings.Unify these settings using macros to hide details and ease porting, and use anew function (mpc85xx_is_qoriq()) to distinguish between QorIQ and QUICC SoCs atruntime.An alternative to using the function could be to use a variable initialized atplatform attach time, which may incur less overhead at runtime. Since it's notin the critical path once booted, this optimization doesn't seem necessary atfirst pass.Reviewed by: nwhitehornMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D7294 List of files: /freebsd/sys/conf/options.powerpc
