* [PATCH V3 0/8] ppc/pnv: Rework on pnv P7IOC initialization
From: Gavin Shan @ 2012-06-25 15:43 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Gavin Shan
The rework is done based on Ben's initial ideas on how PE and resource
assignment is done on top of PCI core instead of doing resource assignment
by powernv platform. With the series of patches, the following aspects will
be covered:
- Only create PE based on PCI bus. Basically, there will be 2 types
of PEs built on PCI bus: (A) PE only includes single PCI bus. (B)
PE includes the PCI bus as well as its subordinate PCI buses.
- Make the I/O and MMIO resources of P2P bridge aligned according to
the PHB's resource layout. For example, MMIO resource of P2P bridges
will be aligned with 16MB if PHB has 16MB M32 segment.
- The resource allocation will be done on basis of PE.
- Trivial fixup on the hook of enabling PCI device, PE check etc.
The series of patches has been verified on Firebird-L and Juno-IOC-L based on
kernel 3.4.RC6. During the kernel boots, USB HUBs can be detected and initialized
correctly. Also, the disk drive as well as network interfaces can work successfully
after booting into shell environment.
V1 -> V2
- Add separate field into "struct pci_host_bridge" to trace the minimal
alignment of prefetchable MMIO bars for P2P bridges (Benjamin Herrenschmidt)
- Reduced variable names while measuring the MMIO bars (Benjamin Herrenschmidt)
- Change the commit log for more clear description on [PATCH 2/8] (Benjamin Herrenschmidt)
- Change the commit log for more clear description on the types of PCI bus
sensitive PEs on [PATCH 5/8] (Richard Yang)
V2 -> V3
- Rework the sequence of the patches so that it won't break "git bitsect" (Benjamin Herrenschmidt)
- Cleanup on variables name so that they have shorter length (Benjamin Herrenschmidt)
- Rework on PE's resource calculation based on the PCI bus (Benjamin Herrenschmidt)
- Cleanup on changelog (Benjamin Herrenschmidt)

* [PATCH 7/8] ppc/pnv: using PCI core to do resource assignment
From: Gavin Shan @ 2012-06-25 15:43 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Gavin Shan
In-Reply-To: <1340639001-28152-1-git-send-email-shangw@linux.vnet.ibm.com>
Currently, the PCI probe flags "PCI_PROBE_ONLY | PCI_REASSIGN_ALL_RSRC"
used on powernv platform. That means the platform has to do the PCI
resource assignment by itself.
The patch changes the PCI probe flag to "PCI_REASSIGN_ALL_RSRC" so
that the PCI core will do the resource assignment. Also, the I/O
and MMIO minimal alignment for P2P bridges have been configured
while doing fixup for the PHBs.

* [PATCH 1/8] ppc/pnv: create bus sensitive PEs
From: Gavin Shan @ 2012-06-25 15:43 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Gavin Shan
In-Reply-To: <1340639001-28152-1-git-send-email-shangw@linux.vnet.ibm.com>
Basically, there're 2 types of PCI bus sensitive PEs: (A) The PE
includes single PCI bus. (B) The PE includes the PCI bus and all
the subordinate PCI buses. At present, we'd like to put PCI bus
originated by PCI-e link to form PE that contains single PCI bus,
and the PCIe-to-PCI bridge will form the 2nd type of PE. We don't
figure out to detect PLX bridge yet. Once we can detect PLX bridge
some day, we have to put PCI buses originated from the downstream
port of PLX bridge to the 2nd type of PE.
The patch changes the original implementation for a little bit
to support 2 types of PCI bus sensitive PEs described as above.
Also, the function used to retrieve the corresponding PE according
to the given PCI device has been changed based on that because each
PCI device should trace the directly associated PE.

* [PATCH 5/8] ppc/pnv: skip check on PE if necessary
From: Gavin Shan @ 2012-06-25 15:43 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Gavin Shan
In-Reply-To: <1340639001-28152-1-git-send-email-shangw@linux.vnet.ibm.com>
While the device driver or PCI core tries to enable PCI device, the
platform dependent callback "ppc_md.pcibios_enable_device_hook" will
be called to check if there has one associated PE for the PCI device.
If we don't have the associated PE for the PCI device, it's not allowed
to enable the PCI device. Unfortunately, there might have some cases
we have to enable the PCI device (e.g. P2P bridge), but the PEs have
not been created yet.
The patch handles the unfortunate cases. Each PHB (struct pnv_phb)
has one field "initialized" to trace if the PEs have been created
and configured or not. When the PEs are not available, we won't check
the associated PE for the PCI device to be enabled.

+DESCRIPTION
+
+The Interlaken is a narrow, high speed channelized chip-to-chip interface. To
+facilitate interoperability between a data path device and a look-aside
+co-processor, the Interlaken Look-Aside protocol is defined for short
+transaction-related transfers. Although based on the Interlaken protocol,
+Interlaken Look-Aside is not directly compatible with Interlaken and can be
+considered a different operation mode.
+
+The Interlaken LA controller connects internal platform to Interlaken serial
+interface. It accepts LA command through software portals, which are system
+memory mapped 4KB spaces. The LA commands are then translated into the
+Interlaken control words and data words, which are sent on TX side to TCAM
+through SerDes lanes.
+
+There are two 4KiB spaces defined within the LAC global register memory map.
+There is a full register set at 0x0000-0x0FFF (also known as the "hypervisor"
+version), and a subset at 0x1000-0x1FFF. The former is a superset of the
+latter, and includes certain registers that should not be accessible to
+partitioned software. Separate nodes are used for each region, with a phandle
+linking the hypervisor node to the normal operating node.
+
+PROPERTIES
+
+ - compatible
+ Usage: required
+ Value type: <string>
+ Definition: Must include "fsl,interlaken-lac". This represents only

have one patch will change parameter all to bus instead of bridge.

ommitdiff;h=3D3dc90c8f31e5e6153e1ac9a903189d3013690e80
in that case, we can just make find_pci_host_bridge() global.

* [PATCH 0/18] powerpc: convert GPR usage to %r0-31 and R0-31
From: Michael Neuling @ 2012-06-25 23:33 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman
Cc: mikey, matt, linuxppc-dev, schwab, Anton Blanchard,
Olof Johannsson
First 5 patches convert us to %r0-31.
Next 12 convert make using R0-31 required in macros.
Last 2 convert instructions where ra = r0 we use 0 rather than the
register value (as suggested by Andreas).
Version 4 add:
Fixes for bpf_jit code
Version 3 adds:
Fixes for chroma (moved some defines ppc_asm.h -> ppc-opcode.h)
Fixed comment in sldi patch to reflect new change (thanks Segher)
Version 2 adds:
ra = 0 idea (as Andreas suggested)
Fixes for 32bit KVM (added ppc44x_defconfig to my testing)
Based on mpe's next tree which has Antons power7 copy patches which
needed fixes for this

The assembler doesn't take %r0 register arguments in braces, so remove them.

* [PATCH 3/18] powerpc: fix usage of register macros getting ready for %r0 change

Anything that uses a constructed instruction (ie. from ppc-opcode.h),
need to use the new R0 macro, as %r0 is not going to work.
Also convert usages of macros where we are just determining an offset
(usually for a load/store), like:
std r14,STK_REG(r14)(r1)
Can't use STK_REG(r14) as %r14 doesn't work in the STK_REG macro since
it's just calculating an offset.

* [PATCH 4/18] powerpc/kvm: sldi should be sld
From: Michael Neuling @ 2012-06-25 23:33 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman
Cc: mikey, matt, linuxppc-dev, schwab, Anton Blanchard,

In-Reply-To: <1340667187.357853.615199632713.qpush@ale>
Since we are taking a registers, this should never have been an sldi.
Talking to paulus offline, this is the correct fix.
Was introduced by:
commit 19ccb76a1938ab364a412253daec64613acbf3df
Author: Paul Mackerras <paulus@samba.org>
Date: Sat Jul 23 17:42:46 2011 +1000
Talking to paulus, this shouldn't be a literal.

* [PATCH 9/18] powerpc: change mtcrf to use real register names

In-Reply-To: <1340667187.357853.615199632713.qpush@ale>
mtocrf define is just a wrapper around the real instructions so we can
just use real register names here (ie. lower case).
Also remove braces in macro so this is possible.

These macros are using integers where they could be using logical
names since they take registers.
We are going to enforce this soon, so fix these up now.

From: Michael Neuling @ 2012-06-25 23:33 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman

Now have ___PPC_RA/B/S/T we can use it in some places. These are
places where we can't use the existing defines which will soon enforce
R0-R31 usage.
The macros being changed here are being used in inline asm, which
can't convert to enforce the R0-R31 usage.
bpf_jit uses a mix of both generated and non-generated with the same
code, so just convert all these to use the ___PPC_R versions which
won't enforce R usage later.

* [PATCH 16/18] powerpc: enforce usage of R0-R31 where possible
From: Michael Neuling @ 2012-06-25 23:33 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman

In-Reply-To: <1340667187.357853.615199632713.qpush@ale>
Enforce the use of R0-R31 in macros where possible now we have all the
fixes in.
R0-R31 macros are removed here so that can't be used anymore. They
should not be defined anywhere.

* [PATCH 18/18] powerpc: enforce usage of RA 0-R31 where possible
From: Michael Neuling @ 2012-06-25 23:33 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman
Cc: mikey, matt, linuxppc-dev, schwab, Anton Blanchard,
Olof Johannsson
In-Reply-To: <1340667187.357853.615199632713.qpush@ale>
Some macros use RA where when RA=R0 the values is 0, so make this
the enforced mnemonic in the macro.
Idea suggested by Andreas Schwab.
