* ide_xfer_verbose() fixups:
- beautify returned mode names
- fix PIO5 reporting
- make it return 'const char *'
* Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode().
* Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid
DMA info in identify block.
* Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update().
As a result DMA won't be tuned or will be disabled after tuning if device
reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the
same checks while the IDE device is probed by ide-{cd,disk} device driver).
* Remove no longer needed ide_dma_verbose().
This patch should fix the following problem with out-of-sync IDE messages
reported by Nick Warne:
hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:
skipping word 93 validity check
, UDMA(66)
and later debugged by Mark Lord to be caused by:
ide_dma_verbose()
printk( ... "2048kB Cache");
eighty_ninty_three()
printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
ide_dma_verbose()
printk(", UDMA(66)"
Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.
v2:
* fixes suggested by Randy:
- use KERN_CONT for printk()-s in ide-{cd,disk}.c
- don't remove argument name from ide_xfer_verbose() declaration
v3:
* Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug()
(spotted by Sergei).
* "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei).
* Fix ide_find_dma_mode() to report the correct mode ('mode' after being
limited by 'req_mode').
