mips: configs: enable I2C_DESIGNWARE_CORE with I2C_DESIGNWARE_PLATFORM

2024-09-09T22:36:52+00:00

The dependency handling of the Synopsys DesignWare I2C adapter drivers is going to be changed so that the glue drivers for the PCI and platform buses depend on I2C_DESIGNWARE_CORE.

MIPS: config: Add ip30_defconfig

2024-07-15T16:17:34+00:00

Add ip30_defconfig derived from ip27_defconfig to ensure this target is build tested by various kernel testing projects. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

MIPS: config: lemote2f: Regenerate defconfig

2024-07-15T16:17:23+00:00

Regenerate defconfig to include some drivers that are used by this platform, including sm712fb, simplefb, rtl8187. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

MIPS: config: generic: Add board-litex

2024-07-15T16:17:07+00:00

The LiteX framework provides a convenient and efficient infrastructure to create FPGA Cores/SoCs. We have implemented LiteX support for a couple of opensource MIPS CPU cores including microAptiv UP from MIPS, GS232 from Loongson, and CDIM from CQU. For this platform, devicetree is generated by litex python scripts so there is no devicetree addition necessary.

MIPS: config: Enable MSA and virtualization for MIPS64R6

2024-07-15T16:16:44+00:00

All MIPS64R6 cores so far supports MSA and vz, so it makes sense to enable them in 64R6 default config. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

mips: configs: ci20: Enable DRM_DW_HDMI

2024-06-11T11:03:11+00:00

Commit 4fc8cb47fcfd ("drm/display: Move HDMI helpers into display-helper module") turned the DRM_DW_HDMI dependency of DRM_INGENIC_DW_HDMI into a depends on which ended up disabling the drivers in the defconfig. Make sure it's still enabled.

MIPS: mobileye: Add EyeQ6H support

2024-06-11T08:15:50+00:00

EyeQ6H (or “High”) is an other SoC from Mobileye still based on the MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC contains 4 cores which are capable of running 4 threads. Besides this, it features multiple controllers such as the classic UART, high speed I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It also includes a Hardware Security Module, Functional Safety Hardware, and video encoders and more. This commit provides the infrastructure to build a kernel running on EyeQ6H SoC. For now the support is limited and only one CPU core is running. Reviewed-by: Jiaxun Yang Signed-off-by: Gregory CLEMENT Signed-off-by: Thomas Bogendoerfer

mips: defconfig: drop RT_GROUP_SCHED=y from generic/db1xxx/eyeq5

2024-06-11T08:14:39+00:00

For cgroup v1, if turned on, and there's any cgroup in the "cpu" hierarchy it needs an RT budget assigned, otherwise the processes in it will not be able to get RT at all. The problem with RT group scheduling is that it requires the budget assigned but there's no way we could assign a default budget, since the values to assign are both upper and lower time limits, are absolute, and need to be sum up to < 1 for each individal cgroup. That means we cannot really come up with values that would work by default in the general case.[1] For cgroup v2, it's almost unusable as well. If it turned on, the cpu controller can only be enabled when all RT processes are in the root cgroup. But it will lose the benefits of cgroup v2 if all RT process were placed in the same cgroup. Red Hat, Gentoo, Arch Linux and Debian all disable it. systemd also doesn't support it.[2] [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1229700 [2]: https://github.com/systemd/systemd/issues/13781#issuecomment-549164383 Signed-off-by: Celeste Liu Signed-off-by: Thomas Bogendoerfer
