[Qemu-devel] [PATCH v3 0/7] target-mips: add support for large physical

From: Leon Alrae
Subject: [Qemu-devel] [PATCH v3 0/7] target-mips: add support for large physical addresses
Date: Tue, 9 Jun 2015 17:42:27 +0100


This patchset adds large physical address support in MIPS, specifically:
* eXtended Physical Addressing (XPA)
* Large Physical Addressing (LPA)

XPA and LPA are enabled in MIPS32R5-generic and MIPS64R6-generic cores

The series applies on top of the Config5.FRE patches.


* adjust mfc0 reading from 64-bit CP0 registers in MIPS32 (Aurelien)
* patch #5 is now first in the series to slightly reduce number of changes

* fix mask used in helper_{d}mtc0_entrylo{0,1} (James)
* remove superfluous brackets (James)
* add missing sign extension in mfhc0 on MIPS64 (this also fixes the issue
  with missing ri/xi masking off)
* take into account CP0_LLAddr_shift (James)
* improve commit message for removing the comments in patch #6 (James)

Leon Alrae (7):
  target-mips: correct MFC0 for CP0.EntryLo in MIPS64
  target-mips: extend selected CP0 registers to 64-bits in MIPS32
  target-mips: support Page Frame Number Extension field
  target-mips: add CP0.PageGrain.ELPA support
  target-mips: add MTHC0 and MFHC0 instructions
  target-mips: remove misleading comments in translate_init.c
  target-mips: enable XPA and LPA features
