From: Cupertino Miranda <cmira...@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. | | Link for Synopsys ARC processor page: | - https://www.synopsys.com/designware-ip/processor-solutions.html | | ARC PRM for both HS and EM processors can be found in: | - https://www.synopsys.com/dw/doc.php/ds/cc/programmers-reference-manual-ARC-EM.pdf | - https://www.synopsys.com/dw/doc.php/ds/cc/programmers-reference-manual-ARC-HS.pdf. | | Looking forward to your comments and suggestions. | | Best regards, | Cupertino Miranda Claudiu Zissulescu (5): arc: Decoder code arc: Opcode definitions table arc: Add IRQ and timer subsystem support arc: Add Synopsys ARC emulation boards tests/tcg: ARC: Add TCG instruction definition tests Cupertino Miranda (7): arc: Add initial core cpu files arc: TCG and decoder glue code and helpers arc: TCG instruction generator and hand-definitions arc: TCG instruction definitions arc: Add BCR and AUX registers implementation arc: Add memory management unit (MMU) support tests/acceptance: ARC: Add linux boot testing.
