Maybe from me, at least the links above refer to messages I sent. IIRC PM support was added to si3124.c in snv_111 and it definitely worked for me. I could access three disks connected to a PM. Wondering why everybody said PMs are not supported by si3124 I googled a bit and found this thread: http://comments.gmane.org/gmane.os.solaris.opensolaris.storage.general/8073 To summarize: PM support worked from snv_111 up to snv_124. Some change in snv_125 seems to have borken it. Looking at http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/io/sata/adapters/si3124/si3124.c it seems a lot (if not all) of PM stuff is already there, see eg. 175 * Port Multiplier: Enumeration of port multiplier is handled during the 176 * controller initialization and also during the a hotplug operation. 177 * Current logic takes care of situation where a port multiplier 178 * is hotplugged into a port which had a cdisk connected previously 179 * and vice versa. 3182 static int 3183 si_enumerate_port_multiplier( 3333 static int 3334 si_read_portmult_reg( 3454 static int 3455 si_write_portmult_reg( 4009 static void 4010 si_recover_portmult_errors( Without any deeper knowledge I would guess that bringing back PM support should only involve some (minor?) tweaking of the existing code. My sincere apologies to everybody I misled by my postings. I should've done some research before posting. Sorry for that.
