* Mega busdma API commit.Scott Long2003-07-011-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour. sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen. If anyone gets panics or warnings from dflt_lock() being called, please let me know right away. Reviewed by: tmm, gibbs Notes: svn path=/head/; revision=117126

* Fix:Gerard Roudier2001-02-111-10/+32
| | | | | | | | | | | | | | | | | | | | - Missing cpu_to_scr() added (endian-ness). Improvement (fix|workaroung??): - Blindly firing a PPR can lead to some messy situations due to various causes or misfeatures, for example: * The 53C1010-[33|66] supports offset 62 in DT mode, but only offset 31 in ST mode. As a result, a PPR(DT, offset 62) responded with PPR(ST, any offset > 31) must be rejected. * A device that doesn't know about PPR should reject it, but may also be confused by this message. When a PPR encounters problems, the driver now patches the goal transfer settings for legacy negotiations to be performed later with the offending target. This give a chance for bad situations to be fixed automagically. Notes: svn path=/head/; revision=72361
* A couple of chip errata work-arounds refined:Gerard Roudier2001-01-281-3/+3
| | | | | | | | | | | | | | | | - When used on a 33MHz PCI BUS, the 53C1010-66 revision 0 requires extra clocks to be inserted in data out phase. Revision 1 is fixed. - The 53C1010-33 revision 1 requires internal cycles to be disabled due to possible contentions on IO registers. Revision 2 is fixed. Fix: - The probing of HVD from GPIO3 bit by the driver was reversed. The driver could misprobe the bus mode of a 825 or 875 chip that was not previously initialized (no BIOS for example).

* This new version adds support for early NCR chips.Gerard Roudier2000-04-296-2109/+4510
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 53C810 non 'A', 53C815 and 53C825 non 'A' are now attached by the driver (by default). The driver uses a different SCRIPTS set based on MEMORY MOVE instructions for these chips. 2 SCRIPTS sets (firmwares) numbered #1 and #2 are used for the whole support of the 53C8XX family to get possible: - FW #1 : Only based on MEMORY MOVE instructions. Selected for 810, 815, 825. - FW #2 : LOAD/STORE based. This is the firmware also used by previous driver versions. Selected for other chips. When both `ncr' and `sym' are configured, `sym' will now attach all the 53C8XX devices by default. Previous balancing between `ncr' and `sym' can be preserved by: - Either editing sym_conf.h and commenting the following compile option: #define SYM_CONF_GENERIC_SUPPORT (This also saves about 3.5Kb of kernel memory). - Or setting kernel config option SYM_SETUP_LP_PROBE_MAP to 64 (bit 0x40) Notes: svn path=/head/; revision=59743

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | support. Changes are rather simplifications of the SCRIPTS interface (prior to complexifying it again;) ), dead code removes and comment fixes. Code removed: - Handling of kernel variables referenced from SCRIPTS. - Handling of selection without ATN. Slightly rewritten: - Handling of illegal phase (4/5) and data overrun conditions. Simplifications: - Extended error flag and bits now only set from the C code. - Move the extended error status (xerr_status) and nego status (nego_status) outside the data structure accessed by SCRIPTS (struct dsb). - Get rid of the script status field (scr_st). - Only patch SCR_NO_OP SCRIPTS instructions to adapt SCRIPTS to actual chip capabilities. Cosmetic changes: - Miscellaneous comments in SCRIPTS. - FreeBSD_4_Bus define replaced by FreeBSD_Bus_Io_Abstraction. Notes: svn path=/head/; revision=59252
* This new driver version uses the DMA mapping interfaceGerard Roudier2000-04-022-320/+1021
| | | | | | | | | | | | | | | | | | | | | | | | | | introduced in FreeBSD-4.0. The driver is now full up-to-date with regards to the current kernel interfaces. Another significant change in this driver version applies to the checking of the data direction. The driver is now able to check against the expected data direction in any circumstance and will not hang either if direction is wrong at the start of the IO, or if for some weird reason, the device changes to the wrong direction during the IO. This driver version is still usable under FreeBSD 3.2/3.3, since it only requires CAM, other kernel interface dependencies being #if'ed in the sources according to kernel version. But, in order to use the driver under those early kernel versions, user has to move the driver sources by hand and make appropriate tiny changes to let the kernel know about the driver. Other changes: - Remove the debugging stuff for WSR bit. - Get rid of some warnings about volatile being discarded. Notes: svn path=/head/; revision=58927
* Simplifications:Gerard Roudier2000-02-132-584/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Remove all the code intended to deal with experimental C1010 revisions. This code got useless due to commercial chip revisions having been fixed. Fixes: - Rewrite/rework the WSR condition handling. Previous drivers snooped on the BUS through the SBDL IO register and this has been discovered to trigger a spurious SCSI parity error when WSR had been set by chip and cleared by SCRIPTS prior to reading SBDL bit [0...7]. On the other hand, the C1010 does not use the SWIDE register when synchronous data transfers are taking place and requires a CHMOV (1) WHEN DATA_IN to be performed in order to move to memory the residual byte when WSR is set and the residual byte is useful data. BTW, the new WSR handling by the driver is simpler. - No longer attempt to read from SCRIPTS the SBDL register. This is intended to avoid to be victimized again by any other issue regarding the handling of this register by 8xx chips. Miscellaneous: - The driver is now able to handle the WSR + IGN RESIDUE condition at the end of a DATA IN I/O without need of a programmed interrupt. It is a minor? optimization. - A few other minor cosmetic changes. This driver version fixes notably a permanent SCSI parity error condition at boot that can be triggerred due to recent changes in cam_xpt.c between 1.79 and 1.80. Changes in CAM/XPT are fine, but the new handling of the full INQUIRY may trigger the driver problem when a target returned an odd value in the `additionnal length' field of the INQUIRY response. The diff against previous driver version is large, but it consists approximatively in: - 350 lignes removed and not compiled in previous drivers (They addressed experimental C1010 revisions) - 250 lignes added or changed, half being comments or empty lines. So, in fact, the real changes are about 120 lines of source. About 80 lines address SCRIPTS changes and about 40 lines address C code changes.
