* [PATCH] s390: wrong interrupt delivered for hsch() or csch()Cornelia Huck2006-03-24
| | | | | | | | | | | | | When cio waits for the interrupt for a basic sense, interrupts for hsch() or csch() issued in the meantime are wrongly counted as interrupts for the basic sense and the accumulated irb is passed to the device driver. In ccw_device_w4sense(), check for clear or halt function in the irb and pass the irb for the csch() or hsch() to the device driver.

* [PATCH] s390: V=V qdio fixesFrank Pavlic2006-02-20
| | | | | | | | | | | | | | | | | Using FCP devices with V=V support, the input queue stalled when CCQ 97 had been returned in qdio_do_eqbs. When this happen we have to reissue the eqbs instruction. Another bug was when V=V was enabled we checked if hardware has SIGA-sync support. If not we returned with 0 from tiqdio_is_inbound_q_done. Thus qdio lost initiative on FCP devices and input queue stalled. Running devices in V=V there is no SIGA-sync support but nevertheless we have to process tiqdio_is_inbound_q_done either.

* [PATCH] s390: qdio V=V pass-throughFrank Pavlic2006-01-06
| | | | | | | | | | | | | | | | | | | New feature V=V qdio pass-through. QDIO and HiperSockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements. Especially the shadowing of SBALs and SLSBs structures in the hypervisor, and the need to issue SIGA SYNC operations to observe state changes, eventually causes significant CPU processing overhead in the hypervisor. The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O.

* [PATCH] fix missing includesTim Schmielau2005-10-30
| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [PATCH] s390: debug feature changesMichael Holzheu2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
