This patchset adds support for Netlogic's XLP processor family.

The CPU_XLR config variable is sufficient for XLR compilation, the
variable NLM_XLR can be removed.

* [PATCH 04/12] MIPS: Netlogic: Move code common with XLP to common/
@ 2011-11-11 11:38 ` Jayachandran C
0 siblings, 0 replies; 44+ messages in thread
From: Jayachandran C @ 2011-11-11 11:38 UTC (permalink / raw)
To: linux-mips, ralf
- Move code that can be shared with XLP (irq.c, smp.c, time.c and
xlr_console.c) to arch/mips/netlogic/common
- Add asm/netlogic/haldefs.h and asm/netlogic/common.h for common and
io functions shared with XLP
- remove type 'nlm_reg_t *' and use uint64_t for mmio offsets
- Move XLR specific code in smp.c to xlr/wakeup.c
- Move XLR specific PCI code from irq.c to mips/pci/pci-xlr.c
- Provide API for pic functions called from common/irq.c

* [PATCH 04/12] MIPS: Netlogic: Move code common with XLP to common/
@ 2011-11-11 11:38 ` Jayachandran C
0 siblings, 0 replies; 44+ messages in thread
From: Jayachandran C @ 2011-11-11 11:38 UTC (permalink / raw)
To: linux-mips, ralf
- Move code that can be shared with XLP (irq.c, smp.c, time.c and
xlr_console.c) to arch/mips/netlogic/common
- Add asm/netlogic/haldefs.h and asm/netlogic/common.h for common and
io functions shared with XLP
- remove type 'nlm_reg_t *' and use uint64_t for mmio offsets
- Move XLR specific code in smp.c to xlr/wakeup.c
- Move XLR specific PCI code from irq.c to mips/pci/pci-xlr.c
- Provide API for pic functions called from common/irq.c
Signed-off-by: Jayachandran C <jayachandranc@netlogicmicro.com>

To: linux-mips, ralf
Add support for Netlogic's XLP MIPS SoC. This patch adds:
* XLP processor ID in cpu_probe.c and asm/cpu.h
* XLP case to asm/module.h
* CPU_XLP case to mm/tlbex.c
* minor change to r4k cache handling to ignore XLP secondary cache
* XLP cpu overrides to mach-netlogic/cpu-feature-overrides.h

* [PATCH 07/12] MIPS: Netlogic: Add XLP platform files for XLP SoC
@ 2011-11-11 11:39 ` Jayachandran C
0 siblings, 0 replies; 44+ messages in thread
From: Jayachandran C @ 2011-11-11 11:39 UTC (permalink / raw)
To: linux-mips, ralf
- Update common files to support XLP.
- Add arch/mips/include/asm/netlogic/xlp-hal for register definitions
and access macros
- Add arch/mips/netlogic/xlp/ for XLP specific files.

* [PATCH 10/12] MIPS: Netlogic: Merge some of XLR/XLP wakup code
@ 2011-11-11 11:40 ` Jayachandran C

To: linux-mips, ralf
Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP. In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.
The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.
Add support for starting XLR and XLP in 1/2/4 threads per core.

* [PATCH 10/12] MIPS: Netlogic: Merge some of XLR/XLP wakup code
@ 2011-11-11 11:40 ` Jayachandran C
0 siblings, 0 replies; 44+ messages in thread
From: Jayachandran C @ 2011-11-11 11:40 UTC (permalink / raw)
To: linux-mips, ralf
Create a common NMI and reset handler in smpboot.S and use this for
both XLR and XLP. In the earlier code, the woken up CPUs would
busy wait until released, switch this to wakeup by NMI.
The initial wakeup code or XLR and XLP are differ since they are
started from different bootloaders (XLP from u-boot and XLR from
netlogic bootloader). But in both platforms the woken up CPUs wait
and are released by sending an NMI.
Add support for starting XLR and XLP in 1/2/4 threads per core.

* [PATCH 12/12] MIPS: Netlogic: Mark Netlogic chips as SMT capable
@ 2011-11-11 11:41 ` Hillf Danton

To: linux-mips, ralf
Netlogic XLR chip has multiple cores. Each core includes four integrated
hardware threads, and they share L1 data and instruction caches.
If the chip is marked to be SMT capable, scheduler then could do more, say,
idle load balancing.
Changes are now confined only to the code of XLR, and hardware is probed
to get core ID for correct setup.

Normally if you're resending other people's patches they should be sent
out with your email in the email's From: header and with the patch
author's name and Email address in a From: line in the first (important,
otherwise git won't parse it right) of the body. Somehow here Hillf
ended up in the From: header which may be confusing, might upset him
and might also trigger spam filters.
No need to resend but you may want to fix that for the next batch of
patches.

Hi Ralf,
The patch was delivered by me, and reprepared under ideas and comments from
you and Jayachandran, thanks. It was fine tuned, and SOB, by Jayachandran, and
included in this patchset, which is far beyond my capability, for supporting
Netlogic chips. And please reconsider the patchset.
Thanks

This was just a comment on the mechanics of sending patches, not a review
of the patch itself - in fact I think it's fine.
What seems to have happened is that Jayachandran prepared the patches
with git-format-patch, then sent them out using mutt -H, not as the
authors of git had intended using git-send-email. Git-send-email
puts the sender's email address into the from header and inserts a From:
into the first line of the body, where needed.
On the receiving side it doesn't change a thing - the patch would have
looked exactly the same after being applied to git but as elaborated
before, there are other problems.
