EDAC, altera: Generalize driver to use DT Memory size · f9ae487e

由 Thor Thayer 提交于 6月 04, 2015

The Arria10 SOC uses a completely different SDRAM controller from the
earlier CycloneV and ArriaV SoCs. The memory size is calculated in the
bootloader and passed via the device tree. Using this device tree size
is more generic than using the register fields to calculate the memory
size for different SDRAM controllers.

EDAC, mce_amd_inj: Modify flags attribute to use string arguments · 0451d14d

由 Aravind Gopalakrishnan 提交于 6月 02, 2015

Use strings such as "hw" or "sw" to indicate the type of error injection
to be performed.

Current flags attribute derives the meanings of values that can be
programmed into it from asm/mce.h. Moving to defined strings for the
attribute allows this module to be self-sufficient and removes the
dependency. Also, we can introduce new flags as and when needed without
having to worry about conflicting with the flags already defined in
asm/mce.h.

Also, modify do_inject() to use the newly defined injection_type enum to
figure out the injection mechanism we need to use

EDAC, xgene: Fix cpuid abuse · 451bb7fb

由 Arnd Bergmann 提交于 6月 01, 2015

The new x-gene EDAC driver incorrectly tried to figure out the version
of one of its IP blocks by looking at the version of the CPU core, which
is only vagely related.

This removes the incorrect code and instead uses the version of the IP
block in the compatible string where it belongs.

Found using build testing on x86, which does not provide the arm64
cpuid interface.

EDAC: Cleanup atomic_scrub mess · b01aec9b

由 Borislav Petkov 提交于 5月 21, 2015

So first of all, this atomic_scrub() function's naming is bad. It looks
like an atomic_t helper. Change it to edac_atomic_scrub().

The bigger problem is that this function is arch-specific and every new
arch which doesn't necessarily need that functionality still needs to
define it, otherwise EDAC doesn't compile.

So instead of doing that and including arch-specific headers, have each
arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c
for ifdeffery. Much cleaner.

And we already are doing this with another symbol - EDAC_SUPPORT. This
is also much cleaner than having CONFIG_EDAC enumerate all the arches
which need/have EDAC support and drivers.

This way I can kill the useless edac.h header in tile too.
