* [PATCH 3/8] pseries: phyp dump: use sysfs to release reserved mem
From: Manish Ahuja @ 2008-02-29 0:27 UTC (permalink / raw)
To: linuxppc-dev, paulus, michael; +Cc: mahuja, linasvepstas
In-Reply-To: <47C74A66.1060105@austin.ibm.com>
Check to see if there actually is data from a previously
crashed kernel waiting. If so, Allow user-sapce tools to
grab the data (by reading /proc/kcore). When user-space
finishes dumping a section, it must release that memory
by writing to sysfs. For example,
echo "0x40000000 0x10000000" > /sys/kernel/release_region
will release 256MB starting at the 1GB. The released memory
becomes free for general use.

Initial patch for reserving memory in early boot, and freeing it later.
If the previous boot had ended with a crash, the reserved memory would contain
a copy of the crashed kernel data.

+
+ Hypervisor-Assisted Dump
+ ------------------------
+ November 2007
+
+The goal of hypervisor-assisted dump is to enable the dump of
+a crashed system, and to do so from a fully-reset system, and
+to minimize the total elapsed time until the system is back
+in production use.
+
+As compared to kdump or other strategies, hypervisor-assisted
+dump offers several strong, practical advantages:
+
+-- Unlike kdump, the system has been reset, and loaded
+ with a fresh copy of the kernel. In particular,
+ PCI and I/O devices have been reinitialized and are
+ in a clean, consistent state.
+-- As the dump is performed, the dumped memory becomes
+ immediately available to the system for normal use.
+-- After the dump is completed, no further reboots are
+ required; the system will be fully usable, and running
+ in it's normal, production mode on it normal kernel.
+
+The above can only be accomplished by coordination with,
+and assistance from the hypervisor. The procedure is
+as follows:
+
+-- When a system crashes, the hypervisor will save
+ the low 256MB of RAM to a previously registered
+ save region. It will also save system state, system
+ registers, and hardware PTE's.
+
+-- After the low 256MB area has been saved, the
+ hypervisor will reset PCI and other hardware state.
+ It will *not* clear RAM. It will then launch the
+ bootloader, as normal.
+
+-- The freshly booted kernel will notice that there
+ is a new node (ibm,dump-kernel) in the device tree,
+ indicating that there is crash data available from
+ a previous boot. It will boot into only 256MB of RAM,
+ reserving the rest of system memory.
+
+-- Userspace tools will parse /sys/kernel/release_region
+ and read /proc/vmcore to obtain the contents of memory,
+ which holds the previous crashed kernel. The userspace
+ tools may copy this info to disk, or network, nas, san,
+ iscsi, etc. as desired.
+
+ For Example: the values in /sys/kernel/release-region
+ would look something like this (address-range pairs).
+ CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: /
+ DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A
+
+-- As the userspace tools complete saving a portion of
+ dump, they echo an offset and size to
+ /sys/kernel/release_region to release the reserved
+ memory back to general use.
+
+ An example of this is:
+ "echo 0x40000000 0x10000000 > /sys/kernel/release_region"
+ which will release 256MB at the 1GB boundary.
+
+Please note that the hypervisor-assisted dump feature
+is only available on Power6-based systems with recent
+firmware versions.
+
+Implementation details:
+----------------------
+
+During boot, a check is made to see if firmware supports
+this feature on this particular machine. If it does, then
+we check to see if a active dump is waiting for us. If yes
+then everything but 256 MB of RAM is reserved during early
+boot. This area is released once we collect a dump from user
+land scripts that are run. If there is dump data, then
+the /sys/kernel/release_region file is created, and
+the reserved memory is held.
+
+If there is no waiting dump data, then only the highest
+256MB of the ram is reserved as a scratch area. This area
+is *not* be released: this region will be kept permanently
+reserved, so that it can act as a receptacle for a copy
+of the low 256MB in the case a crash does occur. See,
+however, "open issues" below, as to whether
+such a reserved region is really needed.
+
+Currently the dump will be copied from /proc/vmcore to a
+a new file upon user intervention. The starting address
+to be read and the range for each data point in provided
+in /sys/kernel/release_region.
+
+The tools to examine the dump will be same as the ones
+used for kdump.
+
+General notes:
+--------------
+Security: please note that there are potential security issues
+with any sort of dump mechanism. In particular, plaintext
+(unencrypted) data, and possibly passwords, may be present in
+the dump data. Userspace tools must take adequate precautions to
+preserve security.
+
+Open issues/ToDo:
+------------
+ o The various code paths that tell the hypervisor that a crash
+ occurred, vs. it simply being a normal reboot, should be
+ reviewed, and possibly clarified/fixed.
+
+ o Instead of using /sys/kernel, should there be a /sys/dump
+ instead? There is a dump_subsys being created by the s390 code,
+ perhaps the pseries code should use a similar layout as well.
+
+ o Is reserving a 256MB region really required? The goal of
+ reserving a 256MB scratch area is to make sure that no
+ important crash data is clobbered when the hypervisor
+ save low mem to the scratch area. But, if one could assure
+ that nothing important is located in some 256MB area, then
+ it would not need to be reserved. Something that can be
+ improved in subsequent versions.
+
+ o Still working the kdump team to integrate this with kdump,
+ some work remains but this would not affect the current
+ patches.
+
+ o Still need to write a shell script, to copy the dump away.
+ Currently I am parsing it manually.

This is going to fire on non-pseries LPAR platforms, like iSeries and
PS3. Which is not what you want I think.

The only changes are in patch 2.
moved early_init_dt_scan_phyp_dump from rtas.c to phyp_dump.c
Added dummy function in phyp_dump.h
Patch 3 required repatching due to changes to patch 2.
Resubmitting all patches to avoid confusion.
Thanks,

I -think- it has it... Pismo definitely has one of the first variant of
UniNorth with "working" FW afaik.
The first UniNorth was used in the first "toilet-seat" ibook, but I
think this one didn't have firewire, or a non-working one... and in the
first Sawtooth G4 for which FW and Ethernet even were separate PCI chips
because the ones in UniNorth were too broken.
It's possible that early G4 titanium powerbooks or other model of FW
iBooks have that UniNorth FW variant too.

* 2.6.25-rc3 Sequoia build - section mismatch(es)
From: Steve Heflin @ 2008-02-28 23:21 UTC (permalink / raw)
To: linuxppc-embedded
Upon building the default Sequoia (AMCC-440EPx) configuration, the
MODPOST step warns about section mismatches:
WARNING: modpost: Found 5 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
After using the CONFIG_DEBUG_SECTION_MISMATCH option, the section
mismatches are cases in one of the following:
1) functions in the device initialization (.devinit)
calls routines which are contained in the .text section;
2) functions in the device init section calls routines in the
device exit section;
3) data structures in the .data section contain pointers to
functions in the .devinit section or .devexit section; (note that
these data structures are used during initialization)
My question is, will this cause the code to malfunction?
thanks,
Steve

Right now the dtc makefiles do this. Though I have created a makefile so

I guess what I see libfdt as something like shared userspace library. At
the moment dtc is the only userspace project to use it. So it make
perfect since to keep it with the source and not separated.
Though when other projects need it .. the option of having to try to
figure out what version of dtc to grab so understand what libfdt is
usable, can be a bit of a pain.
Though I can't really argue that you can't get around this by just
downloading dtc and grabbing out the libfdt package..though it does
cause some indirection.

Actually ouch.. I think you got me dead on :-) .... so basically I am

No device_type, compatible should be "fsl,gianfar-mdio".

The localbus node isn't just a container for flash; if you're not going to

"ranges;".

Should this go under the localbus node?

Actually, in it's current form, it's not. It's built to be statically
linked, not as a shared library (.a vs. .so).

You still haven't explained why maintenance is harder or somehow less
doable by having it in the dtc repo. Maintenance is very much the
concern of the upstream developers, which seem to be saying it's not a
problem for them...

That's akin to saying libcrypto should be broken out to be completely
standalone from openssl. That doesn't make sense either.

Okay, if you say so :)
I based the code on arch/powerpc/platforms/pseries/hotplug-cpu.c

No, the patch looks OK. However, note that non-PPC_CPM_NEW_BINDING code
should go away altogether soon.

I don't have any problems with this, but I think the naming needs to
change. pcibios_* namespace should probably remain arch dependent.
Renaming the unified implementation to pci_enable_resources, and adding
a weak function pcibios_enable_resources that can be overridden by
parisc and arm to enable PERR/SERR after calling the generic
pci_enable_resources function. No?
