Subject: [PATCH v1 00/20] eznps a new ARC platform
Date: Sat, 31 Oct 2015 15:15:07 +0200 [thread overview]
Message-ID: <1446297327-16298-1-git-send-email-noamc@ezchip.com> (raw)
From: Noam Camus <noamc@ezchip.com>
This set introduce new platform to ARC architecture.
Platform name called "eznps" for working with EZchip NPS400
Network Proccessor.
NPS400 is targeted to service "fast path" network applications.
NPS400 got mesh of 256 extended ARC cores (AKA CTOP), each core
got 16 HW threats. This is basically SMT core where at any point of
time only one HW thread is active.
Each core have HW scheduler that round robin between eligible HW
threads. Totaly, kernel sees 4096 CPUs which I belive is a high record.
There is no cache coherency between cores so generic user applications
and kernel do not use D$.
Cores got special memory mappings for huge pages (8MB).
Mapping is static and should provide application enough memory without
any "TLB miss". This mapping is on top of TLB mapping.
This is a basic set that will later be followed with additional
set of patches with all advanced features.
Many thanks to all people helping to make this happen.
Regards,
Noam Camus
Noam Camus (17):
Documentation: Add EZchip vendor to binding list
clocksource: Add NPS400 timers driver
irqchip: add nps Internal and external irqchips
ARC: Set vmalloc size from configuration
ARC: rwlock: disable interrupts in !LLSC variant
ARC: Mark cpu online only after it has executed the per cpu init
hook.
ARC: mm: use generic macros _BITUL()
ARC: add CONFIG_CLKSRC_OF support to time_init()
ARC: [plat-eznps] Add eznps board defconfig and dts
ARC: [plat-eznps] Add eznps platform
ARC: [plat-eznps] Use dedicated user stack top
ARC: [plat-eznps] Use dedicated bitops/atomic/cmpxchg
ARC: [plat-eznps] Use dedicated SMP barriers
ARC: [plat-eznps] Use dedicated identity auxiliary register.
ARC: [plat-eznps] Use dedicated COMMAND_LINE_SIZE
ARC: [plat-eznps] define IPI_IRQ
ARC: Add eznps platform to Kconfig and Makefile
Tal Zilcer (3):
ARC: Use res_service as entry point for secondaries
ARC: [plat-eznps] Use dedicated cpu_relax()
ARC: [plat-eznps] replace sync with proper cpu barrier
