Subject: [PATCH 0/7] microblaze: Define SMP safe operations
Date: Wed, 12 Feb 2020 16:42:22 +0100 [thread overview]
Message-ID: <cover.1581522136.git.michal.simek@xilinx.com> (raw)
Hi,
This is follow up series on the top of cleanup series available here.
https://lkml.org/lkml/2020/2/12/215
There are two things together.
1. Changes in cpuinfo structure in patches 1 and 2
2. Defining SMP safe operations instead of IRQ disabling
Microblaze has 32bit exclusive load/store instructions which should be used
instead of irq enable/disable. For more information take a look at
https://www.xilinx.com/support/documentation/sw_manuals/xilinx2019_2/ug984-vivado-microblaze-ref.pdf
starting from page 25.
Thanks,
Michal
