Subject: [PATCH v4 00/43] Meta Linux Kernel Port
Newsgroups: gmane.linux.kernel
Date: Tuesday 29th January 2013 14:15:10 UTC (over 3 years ago)
This patchset adds core architecture support to Linux for Imagination's
Meta ATP (Meta 1) and HTP (Meta 2) processor cores. I'm now happy with
this patchset as it is. Not a lot has changed since v3 (see below),
which is why I've only included patches which have changed in
non-trivial ways, namely patches 19, 21, 26, 42, 43, but of course
further review and acks are welcome.

The patches are based on v3.8-rc5, and can be found in a more complete
form in the following git tree:
  git://github.com/jahogan/metag-linux.git
metag-core

Meta cores are 32-bit, hardware multithreaded, general purpose, embedded
processors which also feature a DSP instruction set, and can be found in
many digital radios. They are capable of running different operating
systems on different hardware threads, for example a digital radio might
run RTOSes for DAB decoding and audio decoding on 3 hardware threads,
and run Linux on the 4th hardware thread to manage the user interface,
networking etc. HTPs are also capable of running SMP Linux on multiple
hardware threads.

A buildroot tree containing toolchain patches can be found here (use
meta2_defconfig):
  git://github.com/img-meta/metag-buildroot.git
metag-core

Freely available instruction set and architecture overview documents can
be found on the following page:

v4 (tag: metag-core-v4):

changes since v3
* tree:
  * rebased on v3.8-rc5
  * make more use of __core_reg_{get,set} interfaces over inline asm
  * removed the oprofile patch for now until I've looked at wrapping it
    around perf as some other architectures do
* timekeeping
  * move to drivers/clocksource/metag_generic.c (Arnd)
  * use cpu notifier to setup secondary cpu timers
* traps
  * fix lack of critical section restart in kick_handler
* irq handling
  * rename irqchips s/meta/metag/
* scheduling/process management
  * fix idle race (requires use of inline asm to trigger irq entry
    rather than SWITCH instruction) (Arnd)
* build infrastructure & device tree
  * move dtb directory into dts and use common dtb rules (Rob Herring)
* ftrace:
  * remove duplicate include (Steven Rostedt)
* tty/metag_da:
  * addressed review comments (Jiri Slaby)
* fs/imgdafs:
  * clean up fscall similarly to chancall in tty/metag_da


v3 (tag: metag-core-v3):

changes since v2
* tree:
  * rebased on linux-next and related changes
  * integrated generic kernel_thread/kernel_execve into patches
* signals:
  * replace do_notify_resume with do_work_pending containing signal
    handling loop (Al Viro)
  * handlerless local syscall restart (Al Viro)
  * fix rt_sigreturn's do_sigaltstack handling (Al Viro)
  * explicitly detect rt_sigreturn and treat as non-syscall for purposes
    of syscall restart (Al Viro)
  * refactor syscall restart code based on arm
  * use generic sigaltstack
* irq handling:
  * move irq drivers into drivers/irqchip/ (Arnd)
  * switch to sparse irq (Arnd)
  * allow per machine override of nr_irqs
  * switch root TBI, internal, and external interrupt drivers to linear
    irqdomain
  * implement masking in internal interrupt driver
* system calls:
  * remove magic pt_regs 7th syscall argument (Al Viro)
  * use generic sys_clone (Al Viro)
  * fix use of 0 for invalid syscall number (use -1 instead)
* documentation
  * added Documentation/kernel-ABI.txt describing various ABIs (Al Viro)
* tbx:
  * move tbx/tbicache.c to mm/cache.c and refactor / clean up (Joe
    Perches)
  * clean up tbx/tbistring.c
  * rename asm/lock.h->asm/global_lock.h, remove dependence on tbx
  * update all lock users to use asm/global_lock.h rather than tbx
    macros
  * add and use __core_reg_[gs]et macros to replace TBI_[GS]ETREG
  * make use of compiler builtins for cache/tlb handling instructions
    rather than tbx macros
* tty/metag_da:
  * mostly rewritten to address Alan Cox' feedback
  * use del_timer_sync() where appropriate (Alan Cox)
  * convert to use tty_port helpers (Alan Cox)
  * fix tty kref safety (Alan Cox)
  * implement proper output buffering (Alan Cox)
  * fix init error handling
  * implement hangup (Alan Cox)
  * omit specific baud rate (Alan Cox)
* boot:
  * switch to generic CMDLINE Kconfig symbols (Sam Ravnborg)
* alignment patches
  * removed taskstats changes (see "netlink: align attributes on
    64-bits" patches)
  * rework CONFIG_HAVE_64BIT_ALIGNED_ACCESS patch for clarity


v2 (tag: metag-core-v2):

changes based on rfc-v1 review feedback:
* moved build infrastructure patch later (Sam Ravnborg)
* various build system cleanups (Sam Ravnborg)
* split generic build changes out of main build patch (Sam Ravnborg)
* deprecate powervr DT vendor id (Rob Herring)
* ftrace now uses recordmcount.c (Steven Rostedt)
* fixed imgdafs fserrno problem (Al Viro)
* io.h changes, inline asm, removed casts, added metag_in/out (Arnd)
* remove bus_to_virt (Arnd)
* use asm-generic/syscalls.h (Arnd)
* remove superfluous metag_spinlock system call (Arnd)
* renamed packed 64bit arg syscall wrappers (Arnd)

other changes:
* rebased on v3.7-rc8
  * changes based on v3.6..v3.7-rc8 patches
  * uapi disintegration (thanks to David Howells for the assistance)
* add cmpdi2/ucmpdi2 intrinsics and clean up lib Makefile
* fix numa build
* split memory management patch into 6 separate patches to make them
  more manageable and stop them bouncing:
  * cache/tlb handling
  * memory management
  * memory handling
  * huge tlb
  * highmem
  * tcm
* split architecture definitions out of TBX into asm/metag_*.h
* merged remaining TBX header files into a single asm/tbx.h
* split TBX patch into 2 separate patches to stop them bouncing
* merge various similar Kconfig changes in generic code
* dropped sysfs drivers from this patchset (we normally have them turned
  off anyway so they're not a priority)
* renamed dafs to imgdafs
* implemented perf events
* rewrote ptrace to use nicely abstracted regsets
* removed non-standard hw_breakpoints/ptrace API
* use ptrace abstracted context structs in sigcontext
* update DA TTY to be more thread safe and use tty_ports
* switch to generic sys_execve
