* ethtool occationally fails to communicate with with ucc_geth
From: Lennart Sorensen @ 2013-02-06 20:05 UTC (permalink / raw)
To: Li Yang; +Cc: netdev, linuxppc-dev, linux-kernel, Len Sorensen
We are occationally seeing ethtool fail to communicate with ucc_geth.
I think I have tracked down why it happens, but I don't see a good way
to fix it.
When the phy state changes, adjust_link() checks if the state has changed
and if the link is up. If it is it does:
if (new_state) {
/*
* To change the MAC configuration we need to disable
* the controller. To do so, we have to either grab
* ugeth->lock, which is a bad idea since 'graceful
* stop' commands might take quite a while, or we can
* quiesce driver's activity.
*/
ugeth_quiesce(ugeth);
ugeth_disable(ugeth, COMM_DIR_RX_AND_TX);
out_be32(&ug_regs->maccfg2, tempval);
out_be32(&uf_regs->upsmr, upsmr);
ugeth_enable(ugeth, COMM_DIR_RX_AND_TX);
ugeth_activate(ugeth);
}
The problem I believe is that ugeth_quiesce() does netif_device_detach
which clears __LINK_STATE_PRESENT, and hence makes dev_ethtool fail
due to:
if (!dev || !netif_device_present(dev))
return -ENODEV;
So if ethtool happens to be run between ugeth_quiesce() and
ugeth_activate(), it fails as if the device simply doesn't exist, which
is of course not true, it's just temporarily disabled.
I don't see any obvious way to make the ethtool requests block while the
adjust_link does it's business. It seems that that making the device
disappear is the wrong thing to do though.
I am able to make it happen if I do:
'while ethtool ifname; do :; done' while plugging and unplugging the
cable for a few minutes.
Any suggestions?

This seems to be a workaround for a bug in phylib: phy_state_machine()
calls netif_carrier_on() before adjust_link(), so the TX scheduler can
start immediately even though the MAC has not been configured.
A better workaround would be to use netif_carrier_{off,on}() in
ugeth_{quiesce,activate}() respectively instead of
netif_device_{detach,attach}(). But I think phylib really ought to be
fixed.

I am willing to try things, but this is certainly in parts of the network
stack I don't normally poke around in and hence don't know how works.
I just managed to track it down this far. :)
I can try the carrier_off/on in place of the detach/attach and see if
it works.

In x86-64, schedule_user() and do_notify_resume() can be called before
syscall_trace_leave(). As a result we may be entering
syscall_trace_leave() in user mode (from a context tracking POV). To
fix this I added a call to user_exit() on the very beginning of that
function.
You can find the details in 2c5594df344cd1ff0cc9bf007dea3235582b3acf
("rcu: Fix unrecovered RCU user mode in syscall_trace_leave()").
Could this problem happen in ppc as well?

* [RFC][PATCH] powerpc: add Book E support to 64-bit hibernation
From: Wang Dongsheng @ 2013-02-07 2:25 UTC (permalink / raw)
To: linuxppc-dev; +Cc: scottwood, chenhui.zhao, Wang Dongsheng
Update the 64-bit hibernation code to support Book E CPUs.
Some registers and instructions are not defined for Book3e
(SDR reg, tlbia instruction).
SDR: Storage Description Register. Book3S and Book3E have different
address translation mode, we do not need HTABORG & HTABSIZE to
translate virtual address to real address.
More registers are saved in BookE-64bit.(TCR, SPRGx)
Signed-off-by: Wang Dongsheng <dongsheng.wang@freescale.com>
---
Hopefully someone can give me some advice about cache flush. It
confused me that why only 1 MiB is flushed from KERNEL_START on
Book3S. Is there a need to flush L2 cache if I have already flushed
L1 cache? If yes, how about L3 cache? Cache levels are different
in cores, the instruction sets may also be different.

Hi Glauber,
I don't think so. We can offline some of the sections and leave the
reset online.
For example, we store page_cgroups of memory9~11 in memory8. So when we
offline memory8,
we free memory8's page_cgroup storing on other section, but we cannot
free the page_cgroups
being stored in memory8 if memory9~11 are left online.
So we still need to offline memory9~11, and then offline memory8, right ?
I think it makes no difference.
Thanks. :)

The Freescale implementation of the MPIC only allows a single CPU

to check if the Destination registers should be set.
This prevents more than one bit is set at secondary processors

Hi Frederic,
Thank you very much for the reminding.

> Could this problem happen in ppc as well?
I checked the code(64 bit) today, it seems to me that it won't happen.
But fortunately, we are in the ppc mailing list, please correct me if my
understanding is wrong.
By the way, I enabled CONTEXT_TRACKING_FORCE and PROVE_RCU, so if it
could happen, I think there should be some illegal RCU usage complaints
reported.
Thanks, Zhong

Hi Scott,
I measured the power consumption of the whole system on the tqmp2020 ( http=

with a QorIQ P2020.

In idle using nap I got:

0.81W/9.81W =3D 0.083 (8.3 %)

How can I use this interface?

Ah indeed. Looking at syscall_exit_work label in entry_64.S,
do_syscall_trace_leave is called before ret_from_except which is where
we handle user preemption and do_notify_resume. So that looks fine.

Ok.

Make sure that CONFIG_FSL_PMC is enabled, and that you have a pmc node =20
in the device tree. You'll only have standby, not sleep. mpc8536 and =20
p1022 can support what the chip calls "deep sleep" and is exposed as =20
"sleep" rather than "standby", but it doesn't look like the code for =20
that has made it into mainline Linux yet.

From: Aaro Koskinen @ 2013-02-07 23:09 UTC (permalink / raw)

Hi,
I get this BUG when enabling DEBUG_PAGEALLOC with 3.8-rc6+
(6bacaa9ddacb71c691d32c678d37bc59ffc71fac) on G5 PPC.
It seems to be fairly reproducible - I saw it 3 times, soon after booting
while running a compilation job on ext3 partition. Unfortunately I'm
not able to capture the full trace at the moment. Kernel config is below.

* [PATCH] powerpc: Add support for context switching the TAR register
From: Ian Munsie @ 2013-02-08 1:46 UTC (permalink / raw)
To: Benjamin Herrenschmidt, linuxppc-dev
Cc: Michael Neuling, Matt Evans, Ian Munsie
In-Reply-To: <E5260325-626C-47FA-AB0D-56AAA16E2FB1@kernel.crashing.org>
From: Ian Munsie <imunsie@au1.ibm.com>
This patch adds support for enabling and context switching the Target
Address Register in Power8. The TAR is a new special purpose register
that can be used for computed branches with the bctar[l] (branch
conditional to TAR) instruction in the same manner as the count and link
registers.

v2 changelog:
- Encased thread_struct->tar in #ifdef CONFIG_PPC_BOOK3S_64 as per Kumar's
comments
- Rebased on powerpc/next
- Removed definition of CPU_FTR_BCTAR since this already got defined in
"powerpc: Repack 64bit CPU features to remove holes"

Ok. I applied the fix because it was obviously correct vs. the previous
version of the code (ie. the kmalloc was already there)

But a static will be shared by all CPUs or do you mean a per-cpu one ?

What about the stack ? thread info isn't very big...

I suspect that this is caused by the changes to init/Kconfig:

The next line of context is:
default VIRT_CPU_ACCOUNTING if PPC64
Which may have needed changing as well? Indeed, changing that to
VIRT_CPU_ACCOUNTING_NATIVE restores the old defaults.
