HI Anton, thanks for the changes. I have only one concern, has this code
been tried for ucc_geth ? I remember I had some issues with getting the
ucc_geth mdio also working. I will take in these changes and try at my
end for ucc_geth.
-Thanks

Which version your kernel is ? I cant find sandpoint.c in powerpc git tree.
And I suspect it's conditional "if (r3 && r6)" to copy cmd_line, and
your change makes it unconditioned. Maybe it
will affect something.

Right, and I fail to see how it would make any sense the other way
around :-)
Seriously, the map and xlate functions are used to hook up interrupt to
the PIC inputs. So logically, the 3 cascade interrupts are -inputs- to
the parent controller and as such get mapped by that controller. IE. The
parent is the only one to "understand" the format of the "interrupts"
properties for those and the interrupt numbers for those are HW numbers
in the parent space. It wouldn't make -any- sense to call map/xlate of
the child. In fact, for the code in question, the child PIC is just a
device, the fact that that device is itself a PIC is irrelevant.

Yes.

Or you can just keep track of the irq_host * of the FPGA and manually
call irq_create_mapping() passing it a HW number in the FPGA irq space
if you don't want to create device nodes for those children but the
device-node approach is preferred.

> Correct me if i am wrong.
It looks ok except that if I remember correctly, your FPGA PIC has a
#interrupt-cells value of '3' which means that it expects 3 numbers in
the "interrupts" property to define an interrupt (which your xlate
function is then going to translate into the appropriate HW number and
sense/polarity flags for linux).
So if you use only 2 numbers, you need to fix your #interrupt-cells
property value.

I Understood the thing. Thank you very much. So you mean to say that my
map/xlate functions will get invoked only for the devices which is
connected the FPGA PIC. So for example suppose if i have an WDT connected
to my FPGA then the interrupt-parent tag should point to FPGA-PIC. So at
that time the irq_of_parse_and_map() will invoke my map/xlate functions
right.
So i need to define the nodes on my device tree for the devices which are
all going to generate interrupts for FPGA and keeping the interrupt-parent
property as fpga-pic.
So my device node for WDT is something like the following
wdt@4,2000 {
#interrupt-cells = <2>;
device_type = "watchdog";
compatible = "gef,fpga-wdt";
reg = <0x4 0x2000 0x8>;
interrupts = <0x1a 0x4>;
interrupt-parent = <&fpga_pic>;
};
Correct me if i am wrong.

Which means we'd like it in 32 please Ben.
Also Andre, once Ben has merged this you should forward it to

You could just always do an eieio here, it's not expensive at all
compared to the emulation trap itself.
However -- eieio is a Book II insn, it will never trap anyway!

But when MSR[HV]=0 and MSR[PR]=0, mtspr to a hypervisor resource
will not trap but be silently ignored. Sorry for not being more clear.
...Oh. You run your guest as MSR[PR]=1 anyway! Tricky.

I decided to try this in linux-next, but an x86_64 allmodconfig build
gave this (gcc 4.4.0):
ERROR: "__build_bug_on_failed" [drivers/net/virtio_net.ko] undefined!
ERROR: "__build_bug_on_failed" [drivers/block/virtio_blk.ko] undefined!
I assume that this is caused by the "MAYBE_BUILD_BUG_ON(fbit >= 32)" in
virtio_has_feature() (in include/linux/virtio_config.h) which is called
all over the place. Unfortunately, virtio_has_feature() gets uninlined
in those two files ...
I have taken the patch back out again for today.

I inadvertently left that debug code enabled, causing the number of
contexts to be clamped to 31 which is going to slow things down on

* [PATCH RFC] gianfar: Make polling safe with IRQs disabled
From: Anton Vorontsov @ 2009-11-04 22:57 UTC (permalink / raw)
To: David Miller; +Cc: linuxppc-dev, netdev, Andy Fleming, Jason Wessel
When using KGDBoE, gianfar driver spits 'Interrupt problem' messages,
which appears to be a legitimate warning, i.e. we may end up calling
netif_receive_skb() or vlan_hwaccel_receive_skb() with IRQs disabled.
This patch reworks the RX path so that if netpoll is enabled (the
only case when the driver don't know from what context the polling
may be called), we check whether IRQs are disabled, and if so we
fall back to safe variants of skb receiving functions.
Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

I'm not sure if this is suitable for mainline since it doesn't
have KGDBoE support. Jason, if the patch is OK, would you like
to merge it into KGDB tree?

* [PATCH 2/3] fsl_pq_mdio: Fix compiler/sparse warnings (part 2)
From: Anton Vorontsov @ 2009-11-04 22:52 UTC (permalink / raw)
To: David Miller; +Cc: linuxppc-dev, Sandeep Gopalpet, Andy Fleming, netdev
This patch fixes following warnings:
fsl_pq_mdio.c:112:38: warning: cast adds address space to expression (<asn:2>)
fsl_pq_mdio.c:124:38: warning: cast adds address space to expression (<asn:2>)
fsl_pq_mdio.c:133:38: warning: cast adds address space to expression (<asn:2>)
fsl_pq_mdio.c:414:11: warning: cast adds address space to expression (<asn:2>)
Instead of adding __force all over the place, introduce convenient
fsl_pq_mdio_get_regs() call that does the ugly casting just once.

From: Anton Vorontsov @ 2009-11-04 22:52 UTC (permalink / raw)
To: David Miller; +Cc: linuxppc-dev, Sandeep Gopalpet, Andy Fleming, netdev
commit 1d2397d742b7a2b39b2f09dd9da3b9d1463f55e9 ("fsl_pq_mdio: Add
Suport for etsec2.0 devices") introduced the following warnings:

fsl_pq_mdio.c:287: warning: initialization makes pointer from integer without a cast
fsl_pq_mdio.c:287: warning: assignment makes integer from pointer without a cast
These warnings are not easy to fix without ugly __force casts. So,
instead of introducing the casts, rework the code to substitute an
offset from an already mapped area. This makes the code a lot simpler
and less duplicated.
Plus, from now on we don't actually map reserved registers on
non-etsec2.0 devices, so we have more chances to catch programming
errors.

In-Reply-To: <4AF1FB29.50905@austin.ibm.com>
Update the powerpc/iseries vio code to use the new generic OF dynamic code.
NOTE: I have no means of testing iseries kernels, this does at least pass the
compile test for me.

* [RFC PATCH 4/5] Microblaze updates for OF dynamic code
From: Nathan Fontenot @ 2009-11-04 22:19 UTC (permalink / raw)
To: devicetree-discuss, linuxppc-dev, microblaze-uclinux
In-Reply-To: <4AF1FB29.50905@austin.ibm.com>
This patch removes the common OF dynamic device tree updating from the
microblaze prom.c file to now use the generic OF code.
NOTE: I have no means of building and testing for the microblaze architecture.
I'll sign off on this with the understanding that it has not even passed the
compile test yet.

^ permalink raw reply
* [RFC PATCH 3/5] powerpc and pseries updates for new OF dynamic code
From: Nathan Fontenot @ 2009-11-04 22:18 UTC (permalink / raw)
To: devicetree-discuss, linuxppc-dev, microblaze-uclinux
In-Reply-To: <4AF1FB29.50905@austin.ibm.com>
Updates to powerpc generic and powerpc/pseries. This patch removes the
dynamic device tree updating code from prom.c and deletes the no longer
neccessary pSeries_reconfig.h file, all of the functionality is now in the
generic OF code.
The remaining changes deal with updating code for name changes with using
the OF code.
Signed-off-by: Nathan Fonteot <nfont@austin.ibm.com>

^ permalink raw reply
* [RFC PATCH 2/5] Merge dynamic OF code to of_dynamic.c
From: Nathan Fontenot @ 2009-11-04 22:16 UTC (permalink / raw)
To: devicetree-discuss, linuxppc-dev, microblaze-uclinux
In-Reply-To: <4AF1FB29.50905@austin.ibm.com>
Creation of the OF dynamic device tree update code in drivers/of. This
merges the common device tree updating routines to add/remove nodes and
properties from powerpc and microblaze. All of the new code is conditional
based on a new OF_DYNAMIC config option.
There are two updates to the code. First, the routines to update properties
are re-named from prom_* to of_*. This seems correct as the routines no longer
reside in prom.c files. Second, the addition of a notifier chain for when
nodes are added removed from the device tree. This is a feature that currently
exists in powerpc.

This is a follow on to Grant Likely's patches, attempting to merge the common
pieces of dynamic OF device tree updating. These patches move the common
code for adding and removing nodes and properties from the device tree to
drivers/of/of_dynamic.c and wraps them under the new OF_DYNAMIC config
option. Additionally this makes the necessary updates to powerpc and
microblaze arch's for this move.

irq_of_parse_and_map() will call the map/xlate function of the parent
PIC for the given interrupt.
In your case, the interrupts you are calling it for are defined as being
interrupts wiring the FPGA to the MPIC, hence are MPIC inputs, and thus
will be parsed/mapped by the MPIC. From the MPIC standpoint, the FPGA is
just a device.
So the code is doing what you tell it to do :-)
I don't understand what you are actually trying to acheive. If those 3
interrupts aren't outputs from the FPGA to the MPIC but input to the
FPGA then they shouldn't be there, they should be device interrupts
connected to the FPGA. Those will end up with map/xlate called in the
FPGA host.

* RE: DMA to User-Space
From: john.p.price @ 2009-11-04 19:02 UTC (permalink / raw)
To: Jonathan Haws, Bo.Liu; +Cc: linuxppc-dev
In-Reply-To: <BB99A6BA28709744BF22A68E6D7EB51F03310302E2@midas.usurf.usu.edu>
Jonathan, what kind of memory is fpga_drv.strmdata? memory from the
kernel stack, something you allocated? You'll notice you were trying to
access location 0.
To use dma streaming memory you must call dma_map_single() to get the
physical address of fpga_drv.strmdata. That memory must be contiguous.
Then you may call remap_pfn_range with the page offset of the physical
address returned from the dma_map_single() call. Then when the cpu
accesses that region you must sync the region for with dma direction for
cpu or when the device needs to access it, for the device.
LDD3 seems a bit dated on this topic it says to use nopage instead of
remap_pfn_range(), in my experiments remap_pfn_range seemed ok. I would
ask others on the list for their experience on the topic.
Ultimately I went with mapping user space provided address and
implementing dma with scatter-gather.

Can you provide an example for how to do that? I have an mmap routine
to map BARs that the FPGA maintains and I can access those, however when
I try to map the DMA buffer and access what is in it, the system
crashes. Here is the mmap function I have right now:
/* fpga_mmap()
*
* Description:
* The purpose of this function is to serve as a 'file_operation'
* which maps different PCI resources into the calling processes
* memory space.
*
* NOTE: The file offset are in page size; i.e.:
* offset 0 in process's mmap syscall -> BAR0
* offset 4096 in process's mmap syscall -> BAR1
* offset 8192 in process's mmap syscall -> BAR2
* offset 12288 -> Streaming DMA buffer
*
* Arguments:
* struct file *filp -- struct representing an open
file
* struct vm_area_struct *vma -- struct representing memory
'segment'
*
* Returns:
* int -- indication of success or failure
*

Where am I going wrong?
Using mmap() would work well for me.
Also, what about this:
1. I open /dev/mem and get a file descriptor
2. I use mmap to reserve some physical addresses for my buffers in user
space.
3. I give that address to the FPGA for DMA use.
4. When I get the FPGA interrupt, I invalidate the data cache and write
the data to disk
Does that sound like it would work? Would the address I receive from
mmap() and pass to the FPGA be the actual physical address, or would I
need to send the physical address to the FPGA and use the mmap() address
to access and write to disk?
Thanks for the help!
Jonathan

One more question about this approach: does the mmap() call prevent the ker=
nel from using this memory for other purposes? Will the kernel be able to =
"move" this memory elsewhere? I guess what I am asking is if this memory i=
s locked for all other purposes?
