minidump: Use the provided dump bitset When constructing the set of dumpable pages, use the bitset provided by the state argument, rather than assuming vm_page_dump invariably. For normal kernel minidumps this will be a pointer to vm_page_dump, but when dumping the live system it will not. To do this, the functions in vm_dumpset.h are extended to accept the desired bitset as an argument. Note that this provided bitset is assumed to be derived from vm_page_dump, and therefore has the same size. Reviewed by: kib, markj, jhb MFC after: 2 weeks Sponsored by: Juniper Networks, Inc.

powerpc: Use IFUNCs for copyin/copyout/etc Summary: Radix on AIM, and all of Book-E (currently), can do direct addressing of user space, instead of needing to map user addresses into kernel space. Take advantage of this to optimize the copy(9) functions for this behavior, and avoid effectively NOP translations. Test Plan: Tested on powerpcspe, powerpc64/booke, powerpc64/AIM Reviewed by: bdragon Differential Revision: https://reviews.freebsd.org/D25129

powerpc/mmu: Convert PowerPC pmap drivers to ifunc from kobj With IFUNC support in the kernel, we can finally get rid of our poor-man's ifunc for pmap, utilizing kobj. Since moea64 uses a second tier kobj as well, for its own private methods, this adds a second pmap install function (pmap_mmu_init()) to perform pmap 'post-install pre-bootstrap' initialization, before the IFUNCs get initialized.

powerpc64: Implement Radix MMU for POWER9 CPUs Summary: POWER9 supports two MMU formats: traditional hashed page tables, and Radix page tables, similar to what's presesnt on most other architectures. The PowerISA also specifies a process table -- a table of page table pointers-- which on the POWER9 is only available with the Radix MMU, so we can take advantage of it with the Radix MMU driver.

Split the PowerISA 3.0 HPT implementation from historic PowerISA 3.0 makes several changes to not only the format of the HPT but also the behavior surrounding it. For instance, TLBIE no longer requires serialization. Removing this lock cuts buildworld time in half on a 18-core/72-thread POWER9 system, demonstrating that this lock is highly contended on such a system. There was odd behavior observed trying to make this change in a backwards-compatible manner in moea64_native.c, so the best option was to fully split it, and largely revert the original changes adding POWER9 support to the original file.

sys/powerpc: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Introduce inheritance into the PowerPC MMU kobj interface. include/mmuvar.h - Change the MMU_DEF macro to also create the class definition as well as define the DATA_SET. Add a macro, MMU_DEF_INHERIT, which has an extra parameter specifying the MMU class to inherit methods from. Update the comments at the start of the header file to describe the new macros. booke/pmap.c aim/mmu_oea.c aim/mmu_oea64.c - Collapse mmu_def_t declaration into updated MMU_DEF macro The MMU_DEF_INHERIT macro will be used in the PS3 MMU implementation to allow it to inherit the stock powerpc64 MMU methods.

Initial support for Freescale PowerQUICC III MPC85xx system-on-chip family. The PQ3 is a high performance integrated communications processing system based on the e500 core, which is an embedded RISC processor that implements the 32-bit Book E definition of the PowerPC architecture. For details refer to: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8555E This port was tested and successfully run on the following members of the PQ3 family: MPC8533, MPC8541, MPC8548, MPC8555. The following major integrated peripherals are supported: * On-chip peripherals bus * OpenPIC interrupt controller * UART * Ethernet (TSEC) * Host/PCI bridge * QUICC engine (SCC functionality) This commit brings the main functionality and will be followed by individual drivers that are logically separate from this base.

Insert a layer of indirection to the pmap code, using a kobj for the interface. This allows run-time selection of MMU code, based on CPU-type detection, or tunable-overrides when testing new code. Pre-requisite for G5 support. conf/files.powerpc - remove pmap.c - add mmu_if.h, mmu_oea.c, pmap_dispatch.c powerpc/include/mmuvar.h - definitions for MMU implementations powerpc/include/pmap.h - remove pmap_pte_spill declaration - add pmap_mmu_install declaration - size the phys_avail array - pmap_bootstrapped is now global-scope powerpc/powerpc/machdep.c - call kobj_machdep_init early in the boot sequence to allow kobj usage prior to SI_SUB_LOCK - install the OEA pmap code. This will be moved to CPU-specific init code in the future. powerpc/powerpc/mmu_if.m - Kobj MMU interface definitions powerpc/powerpc/pmap_dispatch.c - central dispatch for pmap calls - contains the global mmu kobj and the routine to locate the the mmu implementation and init the kobj
