[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset is prepared for the next 4.21 release for Linux/MIPS. It
add Loongson-3A R2.1 basic support, adds "model name" and "CPU MHz"
knobs in /proc/cpuinfo which is needed by some userspace tools, adds
Loongson-3 kexec/kdump support, and introduces WAR_LLSC_MB to improve
stability.

V1 -> V2:
1, Add Loongson-3A R3.1 basic support.
2, Fix CPU UART irq delivery problem.
3, Improve code and descriptions (Thank James Hogan).
4, Sync the code to upstream.

V2 -> V3:
1, Remove merged patches.
2, Improve code and descriptions (Thank James Hogan).
3, Sync the code to upstream.

V3 -> V4:
1, Remove merged patches.
2, Improve kdump support.
3, Sync the code to upstream.

V4 -> V5:
1, Remove merged patches.
2, Add Loongson-3A R2.1 support.
3, Improve kexec/kdump support.
4, Sync the code to upstream.

Huacai Chen(8):
 MIPS: Loongson: Add Loongson-3A R2.1 basic support.
 MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3.
 MIPS: Ensure pmd_present() returns false after pmd_mknotpresent().
 MIPS: Add __cpu_full_name[] to make CPU names more human-readable.
 MIPS: Align kernel load address to 64KB.
 MIPS: Reserve extra memory for crash dump.
