Documentation: use a source-read extension for the index link boilerplate

2026-01-23T18:59:34+00:00

The root document usually has a special :ref:`genindex` link to the generated index. This is also the case for Documentation/index.rst. The other index.rst files deeper in the directory hierarchy usually don't. For SPHINXDIRS builds, the root document isn't Documentation/index.rst, but some other index.rst in the hierarchy. Currently they have a ".. only::" block to add the index link when doing SPHINXDIRS html builds. This is obviously very tedious and repetitive. The link is also added to all index.rst files in the hierarchy for SPHINXDIRS builds, not just the root document. Put the boilerplate in a sphinx-includes/subproject-index.rst file, and include it at the end of the root document for subproject builds in an ad-hoc source-read extension defined in conf.py. For now, keep having the boilerplate in translations, because this approach currently doesn't cover translated index link headers.

irqchip/loongson-eiointc: Add virt extension support

2024-11-13T08:18:27+00:00

Interrupts can be routed to maximal four virtual CPUs with real HW EIOINTC interrupt controller model, since interrupt routing is encoded with CPU bitmap and EIOINTC node combined method. Here add the EIOINTC virt extension support so that interrupts can be routed to 256 vCPUs in virtual machine mode. CPU bitmap is replaced with normal encoding and EIOINTC node type is removed, so there are 8 bits for cpu selection, at most 256 vCPUs are supported for interrupt routing.

Docs/LoongArch: Add advanced extended IRQ model description

2024-09-24T07:32:20+00:00

Introduce the advanced extended interrupt controllers (AVECINTC). This feature will allow each core to have 256 independent interrupt vectors and MSI interrupts can be independently routed to any vector on any CPU. The whole topology of irqchips in LoongArch machines looks like this if AVECINTC is supported: +-----+ +-----------------------+ +-------+ | IPI | --> | CPUINTC | <-- | Timer | +-----+ +-----------------------+ +-------+ ^ ^ ^ | | | +---------+ +----------+ +---------+ +-------+ | EIOINTC | | AVECINTC | | LIOINTC | <-- | UARTs | +---------+ +----------+ +---------+ +-------+ ^ ^ | | +---------+ +---------+ | PCH-PIC | | PCH-MSI | +---------+ +---------+ ^ ^ ^ | | | +---------+ +---------+ +---------+ | Devices | | PCH-LPC | | Devices | +---------+ +---------+ +---------+ ^ | +---------+ | Devices | +---------+ Signed-off-by: Huacai Chen Signed-off-by: Tianyang Zhang

docs: kernel_feat.py: fix potential command injection

2024-01-11T16:21:01+00:00

The kernel-feat directive passes its argument straight to the shell. This is unfortunate and unnecessary. Let's always use paths relative to $srctree/Documentation/ and use subprocess.check_call() instead of subprocess.Popen(shell=True). This also makes the code shorter. This is analogous to commit 3231dd586277 ("docs: kernel_abi.py: fix command injection") where we did exactly the same thing for kernel_abi.py, somehow I completely missed this one.

The current links of ABI can not be found for some time, let us fix the broken links. By the way, the latest and official ABI documentation releases are available at https://github.com/loongson/la-abi-specs, but there are no Chinese and pdf versions for now, so just do the minimal changes to update the links so that they can be found, hope there are stable links in the future.

and fix all in-tree references. Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy.
