2019-12-09tests: AArch64 Linux as quick regressions (instead of AArch32)Giacomo Travaglini
NOTE: Following the discussion on the current patch review, some regressions have been moved to the long list (realview64-simple-atomic and realview64-simple-timing) in order to reduce computation time. These should be moved back to the quick list as soon as we get more computing power.

riscv asmtest uses multiprocessing.Pool to run multiple gem5 processes concurrently. By using gem5 default options, processes will fail because: - accessing to the same m5out directory - listening too many remote gdb ports at the same time This will set independent m5out directories and disable remote gdb ports for asmtest gem5 processes.

2019-11-14tests: Specify a non-default root folder for regressionsGiacomo Travaglini
The new testlib library is looking for regressions walking from a root folder. This by default points to the tests dir. Since all regressions are supposed to live in the tests/gem5 subdir, the patch is assigning the gem5 subdir as a root directory. This will prevent the example garbage to be printed in the ci framework: Exception thrown while loading "/tmpfs/src/git/jenkins-gem5-prod/tests/long/fs/10.linux-boot/test.py" Ignoring all tests in this file.

2019-10-31mem-ruby: Fixed pipeline squashes caused by aliased requestsJoe Gross
This patch was created by Bihn Pham during his internship at AMD. This patch fixes a very significant performance bug when using the O3 CPU model and Ruby. The issue was Ruby returned false when it received a request to the same address that already has an outstanding request or when the memory is blocked. As a result, O3 unnecessary squashed the pipeline and re-executed instructions. This fix merges readRequestTable and writeRequestTable in Sequencer into a single request table that keeps track of all requests and allows multiple outstanding requests to the same address. This prevents O3 from squashing the pipeline.

2019-08-09tests: Refactor the Gem5Fixture to derive from UniqueFixtureNikos Nikoleris
Gem5Fixture is used to define a fixture for building the gem5 binary. Most tests are expected to define their own Gem5Fixture, however, as some might depend on the same binary (e.g., ./build/ARM/gem5.opt), they will try to re-define a fixture for the same target. This patchset changes Gem5Fixture to derive from UniqueFixture. In addition, this patchset changes the way global fixtures are discovered to work with the new Gem5Fixture class. Instead of enumerating them when test definitions are loaded, we do so after the tests have been filtered according to specified tags (e.g., include opt variant, exclude fast, debug variants).

This changeset adds a test to check the redirection features added in faux-filesystem changeset. The test contains a "chdir" system call to "/proc" which should be redirected to "$(gem5-dir)/m5out/fs/proc" (as specified by the config files). After "chdir", the test subsequently outputs the "/proc/cpuinfo" file which should output a configuration of a fake cpu with values set by a Python configuration file. Note, the test will call "clone" once. To avoid a runtime error, make sure that you run this test with "-n2" supplied to the "config/example/se.py" script.

2018-09-12cpu: Replace the fastmem with a new CPU modelAndreas Sandberg
The AtomicSimpleCPU used to be able to access memory directly to speed up simulation if no caches are used. This is fine as long as no switching between CPU models is required. In order to switch to a new CPU model that requires caches, we currently need to checkpoint the system and restore it into a new configuration. The new 'atomic_noncaching' memory mode provides a solution that avoids this issue since caches are bypassed in this mode. This changeset removes the old fastmem option from the AtomicSimpleCPU and introduces a new CPU, NonCachingSimpleCPU, which derives from the AtomicSimpleCPU. The NonCachingSimpleCPU uses the same mechanism as the AtomicSimpleCPU used to use when accessing memory in when fastmem was enabled. This changeset also introduces a new switcheroo test that tests switching between a NonCachingSimpleCPU and a TimingSimpleCPU with caches.

2018-06-15tests,style: add RISC-V assembly testsTuan Ta
This patch adds a subset (rv64*) of RISC-V assembly tests. The original riscv-test project can be found here: https://github.com/riscv/riscv-tests. The riscv-test project is under the BSD license (https://github.com/riscv/riscv-tests/blob/master/LICENSE) and is maintained separately from gem5 project. The tests have been slightly modified to work in gem5 SE mode: (1) Removed a trap handler used in riscv-tests for bare-metal systems (2) Instead of throwing an exception, the tests call the exit syscall with the exit code of - '0' if SUCCESS - Failed test case's number (non-zero) if FAILURE The exit code can be captured after a simuation completes. In addition to original RISC-V assembly tests, this patch adds several assembly tests specifically for AMO, LR, SC and system calls. Those tests target a multi-core system. (1) rv64uamt: multi-threaded tests for A-extension instructions (2) rv64samt: multi-threaded tests for clone and futex system calls This patch also makes the style checker ignore RISC-V assembly test directory. The assembly tests are maintained in an external project that does not follow the gem5 coding conventions. Please find more details in the README file included in this patch.
