* LCS recovery dumps when cable reconnectKlaus-D. Wacker2008-08-271-1/+2
| | | | | | | | | | LCS recovery dumps in irq routine when CCW address in Subchannel Status Word (SCSW) is zero. This occurs when recovery is driven after cable reconnect. Signed-off-by: Klaus-D.

* lcs: Channel errors drive lcs_recovery which leads to kernel panic.Klaus D. Wacker2007-10-101-3/+8
| | | | | | | | | | | | When the lcs irq routine detects channel failures it drives device recovery. After this event the device is no longer usable for shutdown requests, because the lcs_irq routine may get wrong channel status information. In such a case the lcs_irq routine marks the channel in 'error' state. The channel state comes back to 'running' after restarting the channels. Signed-off-by: Klaus D.

* [PATCH] s390: lcs driver bug fixes and improvements [1/2]Klaus Wacker2006-05-261-170/+171
| | | | | | | | | | | | | | | | Several problems occured with lcs device driver: - device not operational anymore after cable pull/plug-in. - unpredictable results occured, e.g. kernel panic using cards of type QD8F. - STOPLAN and delete multicast address command were not proper recognized by OSA card under heavy network workload. - channel/device error checks missing in interrupt handler. To fix all problems at once recovery of lcs devices has been improved. missing error checks in lcs interrupt handler has been added. Once a hardware problem occurs lcs will recover the device now properly. Signed-off-by: Frank Pavlic <fpavlic@de.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [PATCH] s390: debug feature changesMichael Holzheu2005-06-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the memory allocation method for the s390 debug feature. Trace buffers had been allocated using the get_free_pages() function before. Therefore it was not possible to get big memory areas in a running system due to memory fragmentation. Now the trace buffers are subdivided into several subbuffers with pagesize. Therefore it is now possible to allocate more memory for the trace buffers and more trace records can be written. In addition to that, dynamic specification of the size of the trace buffers is implemented. It is now possible to change the size of a trace buffer using a new debugfs file instance. When writing a number into this file, the trace buffer size is changed to 'number * pagesize'. In the past all the traces could be obtained from userspace by accessing files in the "proc" filesystem. Now with debugfs we have a new filesystem which should be used for debugging purposes. This patch moves the debug feature from procfs to debugfs. Since the interface of debug_register() changed, all device drivers, which use the debug feature had to be adjusted.

* [PATCH] s390: set online race in the lcs driverFrank Pavlic2005-05-151-15/+16
| | | | | | | | | | | | | | | | | [patch 3/10] s390: set online race in the lcs driver. From: Michael Holzheu <holzheu@de.ibm.com> There is a race between lcs_stopcard() and lcs_open_device() which can lead to the error 'lcs: Error in starting channel, rc=-16'. lcs_open_device() is invoked when 'ifconfig up' is called due to a hotplug event, which is caused by register_netdev(). In parallel lcs_stopcard() is executed. Both functions are sending lcs commands. The second invocation fails with -EBUSY (-16) as return value. Move invocation of register_netdev() after invocation of lcs_stopcard to avoid the race. Signed-off-by: Frank Pavlic <pavlic@de.ibm.com>

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+2347
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
