[PATCH 0/6] Add Block-TLB support for hppa target |
Date: |

From: Helge Deller <deller@gmx.de>
All 32-bit hppa CPUs allow a fixed number of TLB entries to have a
different page size than the default 4k.
Those are called "Block-TLBs" and are created at startup by the
operating system and managed by the firmware of hppa machines
through the firmware PDC_BLOCK_TLB call.
This patchset adds the necessary glue to SeaBIOS-hppa and
qemu to allow up to 16 BTLB entries in the emulation.
Signed-off-by: Helge Deller <deller@gmx.de>
Helge Deller (6):
target/hppa: Update to SeaBIOS-hppa version 9
target/hppa: Allow up to 16 BTLB entries
target/hppa: Provide qemu version via fw_cfg to firmware
target/hppa: Add BTLB support to hppa TLB functions
target/hppa: Extract diagnose immediate value
target/hppa: Wire up diag instruction to support BTLB
