2008-04-18ide: remove IDE_*_REG macrosBartlomiej Zolnierkiewicz
* Add IDE_{ALTSTATUS,IREASON,BCOUNTL,BCOUNTH}_OFFSET defines. * Remove IDE_*_REG macros - this results in more readable and slightly smaller code. There should be no functional changes caused by this patch.

Add ide_atapi_{discard_data,write_zeros} inline helpers to <linux/ide.h> and use them instead of home-brewn helpers in ide-{floppy,tape,scsi}.

2008-02-02ide-floppy: bump driver version numberBorislav Petkov
Acknowledge major ide-floppy code refactoring and cleanup by bumping the driver version number. Also, remove a wrong comment. Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove atomic test_*bit macrosBorislav Petkov
..and replace them with flag enums. Bart: - fix idefloppy_media_changed() return value Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: remove unused flag PC_ABORTBorislav Petkov
This flag was never being set in the code so remove it. By the way, the code in the second patch was being executed unconditionally, i.e. in case pc->retries > IDEFLOPPY_MAX_PC_RETRIES is true (actually that is the only case when the outer if-test passed), !test_bit(PC_ABORT, &pc->flags) was always true so the comment is now incorrect and has to go.

2008-02-02ide-floppy: remove IDEFLOPPY_DEBUG_INFOBorislav Petkov

2008-02-02ide-floppy: remove unused IDEFLOPPY_USE_READ12Borislav Petkov
This flag is not being set anywhere in the driver so it can go. Bart: - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: merge idefloppy_{input,output}_buffersBorislav Petkov
We merge idefloppy_{input,output}_buffers() into idefloppy_io_buffers() by introducing a 4th arg. called direction. According to its value we atapi_input_bytes() or atapi_output_bytes(). Also, this simplifies the interrupt handler logic a bit. Finally, rename idefloppy_io_buffers() to ide_floppy_io_buffers().

2008-02-02ide-floppy: use an xfer_func_t and io_buf_t typedefs in order to unify rwBorislav Petkov
Also, move xfer_func_t typedef to the ide.h since it is used by two drivers now (more coming). Bart: - use __func__ while at it Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: mv idefloppy_{should_,}report_errorBorislav Petkov
In addition to shortening the function name, move the printk-call into the function thereby saving some code lines. Also, make the function out_of_line since it is not on a performance critical path. Finally, rename the reworked function to ide_floppy..(). Bart: - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: factor out ioctl handlers from idefloppy_ioctl()Borislav Petkov
By passing idefloppy_floppy_t *floppy to the factored out functions, we get rid of (almost) all local vars so stack usage should be at minimum here. Also, we merge idefloppy_begin_format() into idefloppy_format_start() since it is its only user. Also, rename idefloppy_format_start() to idefloppy_format_unit(). Finally, rename the reworked functions to ide_floppy..(). Bart - minor CodingStyle fixup Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-02ide-floppy: remove struct idefloppy_capacity_descriptorBorislav Petkov
Also, - remove the accompanying 4 byte idefloppy_capacity_header. - rename functions from idefloppy_... to ide_floppy_... after cleanup. - simplify loop in ide_floppy_get_capacity() by reversing if-test condition logically. - finally, fix white space and checkpatch.pl issues Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove struct idefloppy_request_sense_resultBorislav Petkov
While at it, collapse idefloppy_analyze_error() into idefloppy_request_sense_callback() since the latter was its only user. Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove struct idefloppy_capabilities_pageBorislav Petkov
This change is rather temporary and is in preparation of using generic commands as is the case with ide-cd and the uniform cdrom layer (i.e. init_cdrom_command()) However, before this happens, we'll have to remove all typedefs and teach idefloppy_create_mode_sense_cmd() to work directly on u8 buffers. Also, since idefloppy_get_capability_page() was used to read only the sfrp bit, rename the latter so that the name reflects what it does.

2008-02-02ide-floppy: cleanup and unify debugging macro callsBorislav Petkov
* some debug_log() calls were not using "ide-floppy: " prefix * a few used printk levels different than KERN_INFO (KERN_NOTICE and KERN_ERR, which is the default one if no level is given) Bart: - fix build issues for IDEFLOPPY_DEBUG_LOG set to 1 while at it - s/__FUNCTION__/__func__/ Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: disambiguate function namesBorislav Petkov
There were two almost identical function names in ide-floppy.c, which makes their distinction almost impossible. While ide_floppy_release() cleans up the object after the last reference to it has been dropped, idefloppy_release() is the blkdev .release method from struct block_device_operations which releases that last reference. Rename ide_floppy_release() to idefloppy_cleanup_obj() in order to make its purpose more clear. There should be no functionality change resulting from this patch.

Replace the ide-floppy packet commands opcode defines with the generic ones. Add a missing GPCMD_WRITE_12 (opcode 0xaa) to the generic ones in cdrom.h. The last one can be found in the current version of INF-8090, p.905.

2008-02-01ide-{floppy,tape}: remove debug code for dumping identify dataBartlomiej Zolnierkiewicz
IDE core supports dumping raw identify data in hdparm friendly format now so verbose identify dumping in ide-{floppy,tape}.c device drivers (done iff IDE{FLOPPY,TAPE}_DEBUG_INFO is defined to '1' and it is '0' by default) is no longer nedeed.

2007-10-10Introduce rq_for_each_segment replacing rq_for_each_bioNeilBrown
Every usage of rq_for_each_bio wraps a usage of bio_for_each_segment, so these can be combined into rq_for_each_segment.

2007-07-20ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz
Now that ide-floppy supports SG_IO we can add support for SCSI ioctls (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET ones - we can add them later iff really needed). While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from generic_ide_ioctl(): - This prevents ide-{disk,tape,scsi} device drivers from obtaining REQ_TYPE_BLOCK_PC type requests which are currently unsupported by these drivers and which are potentially harmful (as reported by Andrew). - There is no functionality loss since aforementioned ioctls will now be handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl() (for devices using ide-cd driver).
