Technically speaking it's not required to do it, has the data and the instruction cache have been disabled in _start(). However, it may change in the future, so I don't want to rely on this behavior.

| | | | | | | | | | | | | | | | | | | | vmspace_exitfree() and vmspace_free() which could result in the same vmspace being freed twice. Factor out part of exit1() into new function vmspace_exit(). Attach to vmspace0 to allow old vmspace to be freed earlier. Add new function, vmspace_acquire_ref(), for obtaining a vmspace reference for a vmspace belonging to another process. Avoid changing vmspace refcount from 0 to 1 since that could also lead to the same vmspace being freed twice. Change vmtotal() and swapout_procs() to use vmspace_acquire_ref().

Actually, this isn't probably *quite* right yet for one RAID volume, and if we ever end up with finding a device that supports more than one RAID volume (not likely), it probably won't quite be right either. The problem here is that the creating of this 'physical' passthru sim is just a cheap way to leverage off the CAM midlayer to do our negotiation for us on the subentities that make up a RAID volume. It almost causes more trouble than it is worth because we have to remember which side we're talking to in terms of forming commands and which target ids are real and so on. Bleah. + Skip trying to actually do SPI settings for the RAID volumes on the real side of the raid/passthru bus pair- this just confuses the issue. The underlying real physical devices will have the negotiation performed and the Raid volume will inherit the resultant settings. At the sime time, non-RAID devices can be on the same real bus, so *do* perform negotiations with them. + At the end of doing all of the settings twiddling, *ahem*, remember to go update the settings on the card itself (dunno how this got nuked). At this point, negotiations *seem* to be being done (again) correctly for both RAID volumes and their subentities. And they seem to be *mostly* now right for other non-RAID entities on the same bus (I ended up with 3 out of 8 other disks still at narror/async- haven't the slightest idea why yes). Finally, negotiations on a normal bus seem to work (again). There's still more work coming into this area, but we're in the final stretch. Notes: svn path=/head/; revision=159051

| | | | | | | | | | | | | | | | | | | | | Also use BUS_DMA_ALLOCNOW to be on the safe side. 2. Look for the Descriptor Error, and Descriptor Protocol Error flags from the card, and down the interface if we detect either. #1 (along with fixes to busdma) makes sure that this card works in all memory situations. Prior to this change, it was just luck that 512 count RX/TX lists were properly aligned. Now we can use any size of RX/TX lists and still have them properly aligned. #2 ensures that we don't get into an endless interrupt storm if busdma fails us. Descriptor Protocol Error would occur if we misaligned the TX/RX rings, and Descriptor Error would occur if we tried to give the card descriptors or rings with addresses > 1G. Trying to reinitialize the card isn't going to fix these errors, hence we don't try. Notes: svn path=/head/; revision=159013

* Use the limited scatter-gather capabilities of ehci, ohci and uhciIan Dowse2006-05-2814-379/+812
| | | | | | | | | | | | | | | | | | host controllers to avoid the need to allocate any multi-page physically contiguous memory blocks. This makes it possible to use USB devices reliably on low-memory systems or when memory is too fragmented for contiguous allocations to succeed. The USB subsystem now uses bus_dmamap_load() directly on the buffers supplied by USB peripheral drivers, so this also avoids having to copy data back and forth before and after transfers. The ehci and ohci controllers support scatter/gather as long as the buffer is contiguous in the virtual address space. For uhci the hardware cannot handle a physical address discontinuity within a USB packet, so it is necessary to copy small memory fragments at times. Notes: svn path=/head/; revision=158998

After this, I can see both submembers and the raid volumes again, but speed negotiation is still broken.
