Use ARM LDM instead of VFP for uncached reads on Marvell PJ4 · e9f978f3

Siarhei Siamashka authored Oct 17, 2013



Marvell PJ4 core used in CuBox very poorly handles VFP uncached
reads from the framebuffer. Using WMMX or ARM LDM reads is much
faster, with LDM instructions having a minor advantage. This
improves framebuffer read performance from ~50MB/s to ~100MB/s.

WMMX runtime detection and PJ4 core identification is also added
as part of this fix.

CPU: Remove unneeded test program bundled with runtime CPU detection · 66f3e5cc

The 'main' function got there by accident and was not spotted
earlier because the driver itself is a shared library.
