-Subject: ARM64: Dynamically allocate cpumasks and increase supported CPUs to
- 512
-Forwarded: https://lore.kernel.org/lkml/37099a57-b655-3b3a-56d0-5f7fbd49d7db@gentwo.org/

-
-  [ a.k.a. Revert "Revert "ARM64: Dynamically allocate cpumasks and
-    increase supported CPUs to 512""; originally reverted because of a
-    bug in the cpufreq-dt code not using zalloc_cpumask_var() ]
-
-Currently defconfig selects NR_CPUS=256, but some vendors (e.g. Ampere
-Computing) are planning to ship systems with 512 CPUs. So that all CPUs on
-these systems can be used with defconfig, we'd like to bump NR_CPUS to 512.
-Therefore this patch increases the default NR_CPUS from 256 to 512.
-
-As increasing NR_CPUS will increase the size of cpumasks, there's a fear that
-this might have a significant impact on stack usage due to code which places
-cpumasks on the stack. To mitigate that concern, we can select
-CPUMASK_OFFSTACK. As that doesn't seem to be a problem today with
-NR_CPUS=256, we only select this when NR_CPUS > 256.
-
-CPUMASK_OFFSTACK configures the cpumasks in the kernel to be
-dynamically allocated. This was used in the X86 architecture in the
-past to enable support for larger CPU configurations up to 8k cpus.
-
-With that is becomes possible to dynamically size the allocation of
-the cpu bitmaps depending on the quantity of processors detected on
-bootup. Memory used for cpumasks will increase if the kernel is
-run on a machine with more cores.
-
-Further increases may be needed if ARM processor vendors start
-supporting more processors. Given the current inflationary trends
-in core counts from multiple processor manufacturers this may occur.
-
-There are minor regressions for hackbench. The kernel data size
-for 512 cpus is smaller with offstack than with onstack.
-
-Benchmark results using hackbench average over 10 runs of
-
- 	hackbench -s 512 -l 2000 -g 15 -f 25 -P
