Message-Id: <20250811-kunit-mips-v5-1-d6b8fcf3f720@linutronix.de> Date: Mon, 11 Aug 2025 09:07:35 +0200 From: Thomas Weißschuh <thomas.weissschuh@...utronix.de> To: Brendan Higgins <brendan.higgins@...ux.dev>, David Gow <davidgow@...gle.com>, Rae Moar <rmoar@...gle.com> Cc: linux-kernel@...r.kernel.org, linux-kselftest@...r.kernel.org, kunit-dev@...glegroups.com, Thomas Weißschuh <thomas.weissschuh@...utronix.de> Subject: [PATCH v5] kunit: qemu_configs: Add MIPS configurations Add basic support to run various MIPS variants via kunit_tool using the virtualized malta platform. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@...utronix.de> Reviewed-by: David Gow <davidgow@...gle.com> --- Changes in v5: - Rebase on v6.17-rc1 - Drop alreayd applied patch to MIPS core code and related CCs - Link to v4: https://lore.kernel.org/r/20250611-kunit-mips-v4-0-1d8997fb2ae4@linutronix.de Changes in v4: - Rebase on v6.16-rc1 - Pick up reviews from David - Clarify that GIC page is linked to vDSO - Link to v3: https://lore.kernel.org/r/20250415-kunit-mips-v3-0-4ec2461b5a7e@linutronix.de Changes in v3: - Also skip VDSO_RANDOMIZE_SIZE adjustment for kthreads - Link to v2: https://lore.kernel.org/r/20250414-kunit-mips-v2-0-4cf01e1a29e6@linutronix.de Changes in v2: - Fix usercopy kunit test by handling ABI-less tasks in stack_top() - Drop change to mm initialization. The broken test is not built by default anymore. - Link to v1: https://lore.kernel.org/r/20250212-kunit-mips-v1-0-eb49c9d76615@linutronix.de --- tools/testing/kunit/qemu_configs/mips.py | 18 ++++++++++++++++++ tools/testing/kunit/qemu_configs/mips64.py | 19 +++++++++++++++++++ tools/testing/kunit/qemu_configs/mips64el.py | 19 +++++++++++++++++++ tools/testing/kunit/qemu_configs/mipsel.py | 18 ++++++++++++++++++ 4 files changed, 74 insertions(+) diff --git a/tools/testing/kunit/qemu_configs/mips.py b/tools/testing/kunit/qemu_configs/mips.py new file mode 100644 index 0000000000000000000000000000000000000000..8899ac157b30bd2ee847eacd5b90fe6ad4e5fb04 --- /dev/null +++ b/tools/testing/kunit/qemu_configs/mips.py @@ -0,0 +1,18 @@ +# SPDX-License-Identifier: GPL-2.0 + +from ..qemu_config import QemuArchParams + +QEMU_ARCH = QemuArchParams(linux_arch='mips', + kconfig=''' +CONFIG_32BIT=y +CONFIG_CPU_BIG_ENDIAN=y +CONFIG_MIPS_MALTA=y +CONFIG_SERIAL_8250=y +CONFIG_SERIAL_8250_CONSOLE=y +CONFIG_POWER_RESET=y +CONFIG_POWER_RESET_SYSCON=y +''', + qemu_arch='mips', + kernel_path='vmlinuz', + kernel_command_line='console=ttyS0', + extra_qemu_params=['-M', 'malta']) diff --git a/tools/testing/kunit/qemu_configs/mips64.py b/tools/testing/kunit/qemu_configs/mips64.py new file mode 100644 index 0000000000000000000000000000000000000000..1478aed05b94da4914f34c6a8affdcfe34eb88ea --- /dev/null +++ b/tools/testing/kunit/qemu_configs/mips64.py @@ -0,0 +1,19 @@ +# SPDX-License-Identifier: GPL-2.0 + +from ..qemu_config import QemuArchParams + +QEMU_ARCH = QemuArchParams(linux_arch='mips', + kconfig=''' +CONFIG_CPU_MIPS64_R2=y +CONFIG_64BIT=y +CONFIG_CPU_BIG_ENDIAN=y +CONFIG_MIPS_MALTA=y +CONFIG_SERIAL_8250=y +CONFIG_SERIAL_8250_CONSOLE=y +CONFIG_POWER_RESET=y +CONFIG_POWER_RESET_SYSCON=y +''', + qemu_arch='mips64', + kernel_path='vmlinuz', + kernel_command_line='console=ttyS0', + extra_qemu_params=['-M', 'malta', '-cpu', '5KEc']) diff --git a/tools/testing/kunit/qemu_configs/mips64el.py b/tools/testing/kunit/qemu_configs/mips64el.py new file mode 100644 index 0000000000000000000000000000000000000000..300c711d7a82500b2ebcb4cf1467b6f72b5c17aa --- /dev/null +++ b/tools/testing/kunit/qemu_configs/mips64el.py @@ -0,0 +1,19 @@ +# SPDX-License-Identifier: GPL-2.0 + +from ..qemu_config import QemuArchParams + +QEMU_ARCH = QemuArchParams(linux_arch='mips', + kconfig=''' +CONFIG_CPU_MIPS64_R2=y +CONFIG_64BIT=y +CONFIG_CPU_LITTLE_ENDIAN=y +CONFIG_MIPS_MALTA=y +CONFIG_SERIAL_8250=y +CONFIG_SERIAL_8250_CONSOLE=y +CONFIG_POWER_RESET=y +CONFIG_POWER_RESET_SYSCON=y +''', + qemu_arch='mips64el', + kernel_path='vmlinuz', + kernel_command_line='console=ttyS0', + extra_qemu_params=['-M', 'malta', '-cpu', '5KEc']) diff --git a/tools/testing/kunit/qemu_configs/mipsel.py b/tools/testing/kunit/qemu_configs/mipsel.py new file mode 100644 index 0000000000000000000000000000000000000000..3d3543315b45776d0e77fb5c00c8c0a89eafdffd --- /dev/null +++ b/tools/testing/kunit/qemu_configs/mipsel.py @@ -0,0 +1,18 @@ +# SPDX-License-Identifier: GPL-2.0 + +from ..qemu_config import QemuArchParams + +QEMU_ARCH = QemuArchParams(linux_arch='mips', + kconfig=''' +CONFIG_32BIT=y +CONFIG_CPU_LITTLE_ENDIAN=y +CONFIG_MIPS_MALTA=y +CONFIG_SERIAL_8250=y +CONFIG_SERIAL_8250_CONSOLE=y +CONFIG_POWER_RESET=y +CONFIG_POWER_RESET_SYSCON=y +''', + qemu_arch='mipsel', + kernel_path='vmlinuz', + kernel_command_line='console=ttyS0', + extra_qemu_params=['-M', 'malta']) --- base-commit: 5606dd26f0b0d614e64a51e68c86e5066f9a5b71 change-id: 20241014-kunit-mips-e4fe1c265ed7 Best regards, -- Thomas Weißschuh <thomas.weissschuh@...utronix.de>
