Aleksander Jan Bajkowski fbd33d6164 lantiq: enable interrupts on second VPEs 
This patch is needed to handle interrupts by the second VPE on the Lantiq
ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
the second VPE results in a hang. Currently, the vsmp_init_secondary()
function is responsible for enabling these interrupts. It only enables
Malta-specific interrupts (SW0, SW1, HW4 and HW5).

The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
interrupts are wired to an ICU instance. Each VPE has an independent
instance of the ICU. The mapping of the ICU interrupts is shown below:
SW0(IP0) - IPI call,
SW1(IP1) - IPI resched,
HW0(IP2) - ICU 0-31,
HW1(IP3) - ICU 32-63,
HW2(IP4) - ICU 64-95,
HW3(IP5) - ICU 96-127,
HW4(IP6) - ICU 128-159,
HW5(IP7) - timer.

This patch enables all interrupt lines on the second VPE.

This problem affects multithreaded SoCs with a custom interrupt controller.
SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
future, this may be replaced with some generic solution.

Tested on Lantiq xRX200.

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Development

To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
