* [PATCH 3/7] powerpc: Add book3s privileged doorbell exception vectors
From: Ian Munsie @ 2012-11-15 4:49 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Michael Neuling, linuxppc-dev, Ian Munsie
In-Reply-To: <1352954990-2858-1-git-send-email-imunsie@au1.ibm.com>
From: Ian Munsie <imunsie@au1.ibm.com>
Directed Privileged Doorbell Interrupts come in at 0xa00 (or
0xc000000000004a00 if relocation on exception is enabled), so add
exception vectors at these locations.
If doorbell support is not compiled in we handle it as an
unknown_exception.

* powerpc: Add support for POWER8 directed doorbell interrupts
From: Ian Munsie @ 2012-11-15 4:49 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Michael Neuling, linuxppc-dev
This patch series adds support for using directed doorbell interrupts for IPIs
between threads within a core, which is supported by POWER8.
This should avoid the overhead of using XICS to deliver an IPI within a core,
though delivering IPIs between threads of different cores must still use XICS
as before.
Please note that this series depends on this series posted by Michael Neuling,
as it adds additional relocation on exception vectors:

we send a doorbell interrupt.

* [PATCH 7/7] powerpc: Hook up doorbells on server
From: Ian Munsie @ 2012-11-15 4:49 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Michael Neuling, linuxppc-dev, Ian Munsie
In-Reply-To: <1352954990-2858-1-git-send-email-imunsie@au1.ibm.com>
From: Ian Munsie <imunsie@au1.ibm.com>
This patch actually hooks up doorbell interrupts on POWER8:
- Select the PPC_DOORBELL Kconfig option from PPC_PSERIES
- Add the doorbell CPU feature bit to POWER8
- We define a new pSeries_cause_ipi_mux() function that issues a
doorbell interrupt if the recipient is another thread within the same
core as the sender. If the recipient is in a different core it falls
back to using XICS to deliver the IPI as before.
- During pSeries_smp_probe() at boot, we check if doorbell interrupts
are supported. If they are we set the cause_ipi function pointer to
the above mentioned function, otherwise we leave it as whichever XICS
cause_ipi function was determined by xics_smp_probe().

* [PATCH 5/7] powerpc: Add code to handle soft-disabled doorbells on server
From: Ian Munsie @ 2012-11-15 4:49 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Michael Neuling, linuxppc-dev, Ian Munsie
In-Reply-To: <1352954990-2858-1-git-send-email-imunsie@au1.ibm.com>
From: Ian Munsie <imunsie@au1.ibm.com>
This patch adds the logic to properly handle doorbells that come in when
interrupts have been soft disabled and to replay them when interrupts
are re-enabled:
- masked_##_H##interrupt is modified to leave interrupts enabled when a
doorbell has come in since doorbells are edge sensitive and as such
won't be automatically re-raised.
- __check_irq_replay now tests if a doorbell happened on book3s, and
returns either 0xe80 or 0xa00 depending on whether we are the
hypervisor or not.
- restore_check_irq_replay now tests for the two possible server
doorbell vector numbers to replay.
- __replay_interrupt also adds tests for the two server doorbell vector
numbers, and is modified to use a compare instruction rather than an
andi. on the single bit difference between 0x500 and 0x900.
The last two use a CPU feature section to avoid needlessly testing
against the hypervisor vector if it is not the hypervisor, and vice
versa.

* [PATCH 6/7] powerpc: Update Kconfig + Makefile to prepare for server doorbells
From: Ian Munsie @ 2012-11-15 4:49 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Michael Neuling, linuxppc-dev, Ian Munsie
In-Reply-To: <1352954990-2858-1-git-send-email-imunsie@au1.ibm.com>
From: Ian Munsie <imunsie@au1.ibm.com>
Move the rule to build doorbell support out of the Makefile and into a
new Kconfig boolean that platforms can select.
We will add doorbell support to pseries as well in the next patch.

* linux-next: manual merge of the powerpc tree with the signal tree

Hi all,
Today's linux-next merge of the powerpc tree got a conflict in
arch/powerpc/kernel/entry_64.S between commits 40792104b255 ("powerpc:
don't mess with r2 in copy_thread() and friends") and 53b50f9483cc
("powerpc: take dereferencing to ret_from_kernel_thread()") from the
signal tree and commit 12660b170253 ("powerpc: Fix
MAX_STACK_TRACE_ENTRIES too low warning !") from the powerpc tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

If you Linux exception handlers are at low (or high) real addresses, as
usual, you can just "ba" to them?

My bad, didn't notice, I don't have error injection enabled in my test
configs. I think that stuff went in after the original patches were
written I think.
Not a big deal, nobody actually enables that error inject test stuff
just yet, I'll put a fix patch into my "dt" and my "next" branch asap.

Ben.

Hi all,
The code looks correct and inviting to me as it has led to good cleanups.
I dont think passing 0 as the argument to the function
sched_clock_idle_wakeup_event()
should lead to problems,as it does not do anything useful with the
passed arguments.
My only curiosity is what was the purpose of passing idle residency time to
sched_clock_idle_wakeup_event() when this data could always be retrieved from
dev->last_residency for each cpu,which gets almost immediately updated.
But this does not seem to come in way of this patch for now.Anyway I
have added Peter to
the list so that he can opine about this issue if possible and needed.

book3e is different with book3s since 3s includes the exception
vectors code in head_64.S as it relies on absolute addressing
which is only possible within this compilation unit. So we have
to get that label address with got.
And when boot a relocated kernel, we should reset ipvr properly again
after .relocate.

book3e have no real MMU mode so we have to create a 1:1 TLB
mapping to make sure we can access the real physical address.
And correct something to support this pseudo real mode on book3e.

* [PATCH 4/6] book3e/kexec/kdump: introduce a kexec kernel flag
From: Tiejun Chen @ 2012-11-15 9:39 UTC (permalink / raw)
To: benh; +Cc: linuxppc-dev, linux-kernel
In-Reply-To: <1352972396-13489-1-git-send-email-tiejun.chen@windriver.com>
We need to introduce a flag to indicate we're already running
a kexec kernel then we can go proper path. For example, We
shouldn't access spin_table from the bootloader to up any secondary
cpu for kexec kernel, and kexec kernel already know how to jump to
generic_secondary_smp_init.

It makes sense to me for the reserved ranges to be kept with the memory
nodes themselves, even if it does mean that sometimes they need to be
split up for multiple memory nodes.

In-Reply-To: <OF69EAD6CA.250DF267-ON65257AB7.0045C620-65257AB7.0045EB55@in.ibm.com>
[-- Attachment #1: Type: text/plain, Size: 59296 bytes --]
Hello All,
I am trying to bring-up a network interface on my card. The card which is based on PowerPC 440, running linux, has an Intel NIC plugged onto PCIe link.
When I do a ping test , following happens:
1. The card (10.10.10.111) and a PC (10.10.10.2) are connected to a switch. PC has Wireshark installed.2. Pinging from the card to PC - issued ping 10.10.10.2 -c 2 (used a startup script. No serial console)3. PC receives an ARP REQ prior to ICMP from the CARD. <--------- observed on Wireshark installed on the PC.4. PC responses with an ARP RESP .5. the NIC(intel GigE) on the card receives ARP RESP and the NIC counters are incremented. But, Neither DD (Descriptor Done) nor EOP (End Of Packet) bits are set on the descriptor.
When the NIC receives a frame, NIC is supposed to issue the DMA operation to store the received frame to the host buffer and upon successful DMA of the frame to host memory, the NIC is supposed to increment RDH (Receive Descriptor Head) pointer and set DD and EOP bits on the status field of descriptor and has to notify the processor. But that did not happen. I'm fine receiving other interrupts.
Can anyone point out why this can happen? Any pointers would be great help.
Following is the bootlog of the machine: (Userspace prints are observed using ttyprintk method, the lines starting with '[U]' prefixed are from userland)
