| | | | | | | | | | | If a qeth device is set offline, data and control subchannels are cleared, which means removal of all IP Assist Primitive settings implicitly.

| | | | | | | | | | | | For OSA the CHPARM-definition determines the number of available outbound queues. A CHPARM-change may occur while a Linux system with probed OSA device is in suspend state.

* [S390] qdio: outbound tasklet scan thresholdJan Glauber2011-01-051-0/+2
| | | | | | | | | | | | | | | | | | Introduce a scan treshold for the qdio outbound queues. By setting the threshold the driver can tell qdio after how much used SBALs qdio should schedule the outbound tasklet that scans the queue for finished SBALs. The threshold is specific by the drivers because a Hipersockets device is much faster in utilizing outbound buffers than a ZFCP or OSA device. The default values after how many used SBALs the tasklet should run are: OSA: > 31 SBALs Hipersockets: > 7 SBALs zfcp: > 55 SBALs Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | | For a certain Hipersockets specific error code in the xmit path, the qeth driver tries to invoke dev_queue_xmit again. Commit 79640a4ca6955e3ebdb7038508fa7a0cd7fa5527 introduces a busylock causing locking problems in case of re-invoked dev_queue_xmit by qeth.

* qeth: NAPI support for l2 and l3 disciplineFrank Blaschka2010-09-081-2/+24
| | | | | | | | | | | | | This patch adds NAPI support to the qeth layer 2 and layer 3 discipline. It is important to understand that we can not enable/disable IRQs as usual, we have to use the corresponding new QDIO interface. Also to not overdraw the budget we have to stop and restart buffer processing at any point during processing a bulk of QDIO buffers. Having the driver NAPI enabled it is possible to turn on GRO for the layer 3 discipline. Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* qeth: rework TSO functionsFrank Blaschka2009-11-161-35/+2
| | | | | | | | | | | The maximum TSO size OSA can handle is 15 * PAGE_SIZE. This patch reduces gso_max_size to this value and adds some sanity checks and statistics to the TSO implementation. Since only layer 3 is able to do TSO move all TSO related functions to the qeth_l3 module. Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

* qeth: Recognize return codes of ccw_device_set_onlineUrsula Braun2009-11-161-10/+16
| | | | | | | | | | | | | | Setting a qeth device online requires to call function ccw_device_set_online() for read-, write-, and data-subchannel. Failures should be detected immediately without an attempt to invoke follow-on activity qeth_qdio_clear_card()., In addition, ccw_device_set_online calls are consolidated in qeth_core_main.c only.

* qeth: Exploit Connection IsolationEinar Lueck2009-11-161-0/+151
| | | | | | | | | | | Isolate data connection to a shared OSA card against other data connections to the same OSA card. Connectivity between isolated data connections sharing the same OSA card is therefore possible only through external network gear (e.g. a router).

* qeth: Convert ethtool get_stats_count() ops to get_sset_count()Ben Hutchings2009-10-051-3/+8
| | | | | | | | | This string query operation was supposed to be replaced by the generic get_sset_count() starting in 2007. Convert qeth's implementation. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* qeth: display service_level info only when valid.Klaus-Dieter Wacker2009-08-261-2/+3
| | | | | | | | | | qeth displayed an entry in /proc/service_level even when no valid MCL-string was available (the MCL info is blank). The change is to create an entry in /proc/service_level only when MCL-string is non-zero. Signed-off-by: Klaus-Dieter Wacker <kdwacker@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* qeth: Cleanup for cast-type determination.Klaus-Dieter Wacker2009-08-261-49/+0
| | | | | | | | | Clear separation of cast-type determination (send path) for layer-2 resp. layer-3. Allowing to have inline functions for qeth layer- discipline. Signed-off-by: Klaus-Dieter Wacker <kdwacker@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* qeth: HiperSockets SIGA retry support on CC=2.Klaus-Dieter Wacker2009-08-261-8/+52
| | | | | | | | | | Qeth HiperSockets support now retries sending of packets when the IBM System z signals a temporary resource shortage (e.g. target buffer full). The packet is enqueued into the device queue. After 3 times of unsuccessful send the packet is dropped. Signed-off-by: Klaus-Dieter Wacker <kdwacker@de.ibm.com> Signed-off-by: David S.
