Subject: [PATCH 0/1] Initial ARMv7-A LPAE support
Date: Tue, 3 Feb 2026 14:19:44 +0000 [thread overview]
Message-ID: <20260203141945.1417902-1-renaud.barbier@ametek.com> (raw)
The LPAE support allows to map physical address above the 32-bit space in
the ARMv7-A processor to a 32-bit virtual address.
This patch set was tested on a LS1021A-IOT. Later, a patch to the PCIe
designware driver will be provided to prove the remapping of 40-bit PA to
32-bit VA.
This patch does not include an update of the mmuinfo command.
