From: Cupertino Miranda <cmiranda at synopsys.com>
Hello everyone,
Here is a long due refresh of ARCv2 port patches.
List of done requested improvements:
- Include acceptance tests for ARC (linux boot),
- Copyright notices,
- Remove osdep.h from header files,
- Removed makefiles,
- Cleared list of boards reducing for just 2 boards
Things requested but not done:
- f4bug: we did not change any of the mentioned variable types since those
variables are used in global properties, and the property definition
seem to enforce a size and signess, when using DEFINE_PROP_UNSIGNED.
Best regards,
Cupertino Miranda
| Hello everyone,
|
| It is with utmost pleasure that on behalf of Synopsys I initiate the
| upstream process for our ARCv2 architecture QEMU port.
|
| I am one of the main contributors to this port and member of the
| Synopsys GNU toolchain team, together with Claudiu Zissulescu and
| Shahab Vahedi.
|
| ARCv2 processors use RISC, and employ the 16-/32-bit instruction set
| architecture (ISA).
| ARC processors are configurable and extensible for a wide range of uses
| in system on a chip (SoC) devices.
| It is a common processor in deeply embedded systems, used in storage,
| digital home, mobile, automotive, and Internet of Things (IoT)
| applications.
|
| To facilitate reviewing, we split the files through several commits,
| attempting to keep file size to reviewable chunks.
|
| The port as presented implements the system softmmu hardware emulation,
| capable to boot and run Linux kernel.
| It has also been integrated as a patch in Zephyr project, where it is
| being used.
| To validate and guarantee correctness of the port through development,
| we have created TCG tests from the very beggining, covering the most
| fundamental CPU features.
| For the remaining instructions we validate the port through compiler
| testsuites, like DejaGNU, comparing results with real hardware
| executions.
|
| Would like also to thank our colleagues Vineet Gupta and Alexey Broadkin
| for their contributions, which due to the collapse of the development
| commits, got their contributions overcast by major ones.

| Looking forward to your comments and suggestions.
