2010-01-04[S390] qdio: convert global statistics to per-device statsJan Glauber7-265/+177
Revamp the qdio performance statistics and move them from procfs to debugfs using the seq_file interface. Since the statistics are not intended for the general user the removal of /proc/qdio_perf should not surprise anyone. The per device statistics are disabled by default, writing 1 to /<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the statistics for the given device.

2009-12-18[S390] qdio: add counter for input queue full conditionJan Glauber3-1/+5
Add a counter to the qdio performance statistics that indicates that no free buffers were left in the input queue. If the counter gets increased it means that the qdio adapter filled all available buffers and possibly had more buffers ready but could not transmit them.

2009-12-18[S390] cio: fix channel path varyPeter Oberparleiter3-14/+19
Channel path vary is currently broken: channel paths which are varied offline are still used by Linux. The reason for this is that: * the path mask indicating which paths of an I/O device can be used is reset by each internal I/O request * the logic that checks if a path group is already in its designated target state incorrectly interprets the result "is correctly set" as "is correctly set and available" Fix this by resetting the path mask only for internal I/O requests which affect the path mask and by correcting the pgid check logic.

2009-12-15tree-wide: convert open calls to remove spaces to skip_spaces() lib functionAndré Goddard Rosa1-2/+3
Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Cc: Julia Lawall <julia@diku.dk> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Jeff Dike <jdike@addtoit.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: "H.

Support for special command is implemented in the AP Bus in the NQAP function __ap_send. This is extended for a further parameter special. When set, the special bit, in GR0 will be set. Therefor the ap_message struct is extended for a further bit. Thus calling functions of __ap_send can use the special parameter in ap_message to give to __ap_send. Affected is in the first place ap_queue_message, which is called by the actual card driver. The second part of this support is that the card driver for the CEX3C needs to set this special bit, when an according CPRB is sent to the driver.

2009-12-07[S390] dasd: let device initialization wait for LCU setupStefan Weinhuber3-14/+89
The first DASD that is set online for a specific logical control unit has to do certain setup steps on the storage server to make full use of it, for example it will enable PAV. The features and characteristics reported by the storage server will depend on this setup, so all other devices on the same LCU will need to wait for the setup to be finished.

2009-12-07[S390] dasd: improve error recovery for internal I/OStefan Weinhuber6-94/+253
Most of the error conditions reported by a FICON storage server indicate situations which can be recovered. Sometimes the host just needs to retry an I/O request, but sometimes the recovery is more complex and requires the device driver to wait, choose a different path, etc. The DASD device driver has a fully featured error recovery for normal block layer I/O, but not for internal I/O request which are for example used during the device bring up. This can lead to situations where the IPL of a system fails because DASD devices are not properly recognized. This patch will extend the internal I/O handling to use the existing error recovery procedures.
