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
