Requested by: Stefan Esser (se at freebsd dot org)[1] Reviewed by: jhb, scottl [1] Stefan requested this be part of 8.0 but has been unavailable to do the MFC since submitting the request. We want to get 8.0-RC3 started so I'm doing the merges with re@ hat on. 2008-10-14T20:18:57Z Marius Strobl marius@FreeBSD.org 2008-10-14T20:18:57Z urn:sha1:1675bf71aeb374223ef6ed952d49d326c6c26d56 MFC after: 1 month 2008-08-07T23:41:17Z Marius Strobl marius@FreeBSD.org 2008-08-07T23:41:17Z urn:sha1:a91a964c748fb1c18e4e553b28fbec0c7ee371a6 MFC after: 3 days 2008-05-15T20:27:18Z Marius Strobl marius@FreeBSD.org 2008-05-15T20:27:18Z urn:sha1:d7405474eac5d1b9f950164e8d7a4b015d2293c5 - Obsolete redundant inst_name and unit members of struct sym_hcb. - Fix three more NULL vs. 0 confusions. - Use device_set_softc(9) to tell the bus layer that this driver allocates a instance of struct sym_hcb itself. 2008-04-24T22:48:34Z Marius Strobl marius@FreeBSD.org 2008-04-24T22:48:34Z urn:sha1:82897554f5e88752948491b038357b453068ba2b in order to get rid of bus space handle and tag in struct sym_hcb. - Remove unused members related to bus addresses in struct sym_hcb. - sym(4) takes care of allocating an instance of struct sym_hcb itself so don't let newbus allocate it as an unused softc also. - Add basic MPSAFE locking. This includes changing the sym(4) CCBs to be allocated up-front instead of on demand as needed. Besides making these allocations more likely to succeed, this also solves the problem of calling bus_dmamap_create(9) with the SIM mutex held.

This is a porblem in the case of the Symbios driver, since the SCRIPTS engine in the SCSI chip operates on physical addresses and needs physically contiguous memory. Earlier patches used contigmalloc on amd64, but this version replaces part of a structure by a pointer to that data. In order to not introduce an extra indirection for other architectures, the change has been made conditional on __amd64__. Earlier attempts to repair this problem are removed (i.e. the macros that made amd64 use contigmalloc). The fix was submitted by Jan Mikkelsen and modified by me to only affect amd64.
