Subject: [DistroKit] [PATCH v1 1/9] mipsel: kernel-malta: set page size to 4k
Date: Fri, 16 Aug 2024 14:52:09 +0200	[thread overview]
Message-ID: <20240816125217.1900626-1-o.rempel@pengutronix.de> (raw)

QA tool complains:
4KiB page size is the most common supported page size across
architecture with best software compatibility and least internal
fragmentation.  This comes at the cost of increased TLB usage and page
table size.

For more server-like workloads (more processes, larger executables), a
bigger page size can be a better trade-off, but the rationale should be
explicitly documented by overriding this check.
