1.5	06-Sep-2025	riastradh	pvscsi(4): Zero rings before using them. bus_dmamem_alloc(9) doesn't guarantee zeroing, as far as I can tell, and who knows what might happen if the ring header and contents have anything nonzero initially. Insert an initial preread/prewrite sync between zeroing and first use, and, out of paranoia, a final postread/postwrite sync between last use and unload/free. Prompted by (but not really related to): PR kern/59618: occasional virtio block device lock ups/hangs
1.4	06-Sep-2025	riastradh	pvscsi(4): Use bus_dmamap_sync, not membar_, for DMA. membar_ may be a noop if we're booting on a single _virtual_ CPU, but the barriers are still needed in case the host behind pvscsi(4) is running on another _physical_ CPU. Prompted by (and related to but not the same issue as): PR kern/59618: occasional virtio block device lock ups/hangs
1.3	06-Sep-2025	riastradh	pvscsi(4): Use paravirt_membar_sync(9) where needed. PR kern/59618: occasional virtio block device lock ups/hangs (pvscsi(4) is not virtio(4) but the same fundamental issue arises.)
1.2	05-Aug-2025	skrll	branches: 1.2.2; 1.2.4; Add the barrier that a comment describes.
1.1	04-Aug-2025	skrll	Add a port of the FreeBSD driver for the VMware PV SCSI controller found in VMware's ESXi product. Tested on ESXi/Arm such that an installation from ISO succeeds and boots.
1.2.4.2	08-Aug-2025	martin	Pull up following revision(s) (requested by skrll in ticket #1148): sys/arch/evbarm/conf/GENERIC64: revision 1.227 sys/dev/pci/files.pci: revision 1.451 sys/dev/pci/pvscsi.c: revision 1.1 sys/dev/pci/pvscsi.c: revision 1.2 sys/dev/pci/pvscsi.h: revision 1.1 sys/arch/amd64/conf/GENERIC: revision 1.617 Add a port of the FreeBSD driver for the VMware PV SCSI controller found in VMware's ESXi product. Tested on ESXi/Arm such that an installation from ISO succeeds and boots. Add the barrier that a comment describes.
