2022-01-07docs: automarkup.py: Fix invalid HTML link output and broken URI fragmentsJames Clark
Since commit d18b01789ae5 ("docs: Add automatic cross-reference for documentation pages"), references that were already explicitly defined with "ref:" and referred to other pages with a path have been doubled. This is reported as the following error by Firefox: Start tag "a" seen but an element of the same type was already open. End tag "a" violates nesting rules. As well as the invalid HTML, this also obscures the URI fragment links to subsections because the second link overrides the first. For example on the page admin-guide/hw-vuln/mds.html the last link should be to the "Default Mitigations" subsection using a # URI fragment: admin-guide/hw-vuln/l1tf.html#default-mitigations But it is obsured by a second link to the whole page: admin-guide/hw-vuln/l1tf.html The full HTML with the double <a> tags looks like this: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref"> <a class="reference internal" href="l1tf.html"> <span class="doc">L1TF - L1 Terminal Fault</span> </a> </span> </a> After this commit, there is only a single link: <a class="reference internal" href="l1tf.html#default-mitigations"> <span class="std std-ref">Documentation/admin-guide/hw-vuln//l1tf.rst</span> </a> Now that the second link is removed, the browser correctly jumps to the default-mitigations subsection when clicking the link. The fix is to check that nodes in the document to be modified are not already references. A reference is counted as any text that is a descendant of a reference type node. Only plain text should be converted to new references, otherwise the doubling occurs. Testing ======= * Test that the build stdout is the same (ignoring ordering), and that no new warnings are printed. * Diff all .html files and check that the only modifications occur to the bad double links. * The auto linking of bare references to pages without "ref:" is still working.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2022-01-06 1) Expose FEC per lane block counters via ethtool 2) Trivial fixes/updates/cleanup to mlx5e netdev driver 3) Fix htmldoc build warning 4) Spread mlx5 SFs (sub-functions) to all available CPU cores: Commits 1..5 Shay Drory Says: ================ Before this patchset, mlx5 subfunction shared the same IRQs (MSI-X) with their peers subfunctions, causing them to use same CPU cores. In large scale, this is very undesirable, SFs use small number of cpu cores and all of them will be packed on the same CPU cores, not utilizing all CPU cores in the system. In this patchset we want to achieve two things. a) Spread IRQs used by SFs to all cpu cores b) Pack less SFs in the same IRQ, will result in multiple IRQs per core. In this patchset, we spread SFs over all online cpus available to mlx5 irqs in Round-Robin manner. e.g.: Whenever a SF is created, pick the next CPU core with least number of SF IRQs bound to it, SFs will share IRQs on the same core until a certain limit, when such limit is reached, we request a new IRQ and add it to that CPU core IRQ pool, when out of IRQs, pick any IRQ with least number of SF users. This enhancement is done in order to achieve a better distribution of the SFs over all the available CPUs, which reduces application latency, as shown bellow. Machine details: Intel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz with 56 cores. PCI Express 3 with BW of 126 Gb/s. ConnectX-5 Ex; EDR IB (100Gb/s) and 100GbE; dual-port QSFP28; PCIe4.0 x16.

Numbers: latency = 15.136 usec, CPU Util = 35% Test description: There are 250 SFs on the system. There are 3 instances of netperf running, on-top three different SFs, in parallel.

The last two entries (#3 and #4) shows the latency reduction improvement of this patch. e.g.: SFs are on different CPUs. - Whenever we use several CPUs, in case there is a different CPU utilization, write the utilization of each CPU separately. - Whenever the latency result of the netperf instances were different, write the latency of each netperf instances separately.

2022-01-03Documentation: refer to config RANDOMIZE_BASE for kernel address-space ↵Lukas Bulwahn
randomization The config RANDOMIZE_SLAB does not exist, the authors probably intended to refer to the config RANDOMIZE_BASE, which provides kernel address-space randomization. They probably just confused SLAB with BASE (these two four-letter words coincidentally share three common letters), as they also point out the config SLAB_FREELIST_RANDOM as further randomization within the same sentence. Fix the reference of the config for kernel address-space randomization to the config that provides that.

2022-01-03Documentation: kgdb: properly capitalize the MAGIC_SYSRQ configLukas Bulwahn
Most readers are probably going to figure out that the config is actually all upper-case letters, as all Kconfig symbols are this way.

So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb documentation.
