[Qemu-devel] [PATCH v4 0/5][RFC] New SPARC machine: Leon3

[Fabien Chouteau <chouteau@adacore.com>]

Hello Qemu-devel,

Here is the fourth version of Leon3 emulation patch-set.

Modifications since v3:
 - Tracepoints in leon3.c
 - Fix compilation error in user mode (target-sparc/op_helper.c)
 - Remove unused variable in leon3.
 - Minor reformating (style errors from checkpatch.pl)

Please feel free to comment.

Regards,

-------------------------------------------------------------------------------

This patch set introduces a new SPARC V8 machine: Leon3. It's an open-source
VHDL System-On-Chip, well known in space industry (more information on
http://www.gaisler.com).

Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

Modifications have been done to the SPARC cpu emulation code to handle
Leon3's specific behavior:
 - IRQ management
 - Cache control
 - Asr17 (implementation-dependent Ancillary State Registers)
 - Shutdown

Fabien Chouteau (5):
  SPARC: Emulation of GRLIB GPTimer
  SPARC: Emulation of GRLIB IRQMP
  SPARC: Emulation of GRLIB APB UART
  SPARC: Emulation of Leon3
  SPARC: Add asr17 register support
