Impact: clean up The code in process_ver_nack is a little obfuscated. This change makes it a bit more readable by humans. It removes the complex if statement and replaces it with a cleaner flow of control.

o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

We're calling request_irq() with a IRQs disabled. No straightforward fix exists because we want to enable these IRQs and setup state atomically before getting into the IRQ handler the first time. What happens now is that we mark the VIRQ to not be automatically enabled by request_irq(). Then we make explicit enable_irq() calls when we grab the LDC channel. This way we don't need to call request_irq() illegally under the LDC channel lock any more. Bump LDC version and release date. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Since we have to be able to handle MD updates, having an in-tree set of data structures representing the MD objects actually makes things more painful. The MD itself is easy to parse, and we can implement the existing interfaces using direct parsing of the MD binary image. The MD is now reference counted, so accesses have to now take the form: handle = mdesc_grab(); ... operations on MD ... mdesc_release(handle); The only remaining issue are cases where code holds on to references to MD property values. mdesc_get_property() returns a direct pointer to the property value, most cases just pull in the information they need and discard the pointer, but there are few that use the pointer directly over a long lifetime. Those will be fixed up in a subsequent changeset. A preliminary handler for MD update events from domain services is there, it is rudimentry but it works and handles all of the reference counting. It does not check the generation number of the MDs, and it does not generate a "add/delete" list for notification to interesting parties about MD changes but that will be forthcoming.

All of the interrupts say "LDX RX" and "LDX TX" currently which is next to useless. Put a device specific prefix before "RX" and "TX" instead which makes it much more useful. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

1) LDC_MODE_RELIABLE is deprecated an unused by anything, plus it and LDC_MODE_STREAM were mis-numbered. 2) read_stream() should try to read as much as possible into the per-LDC stream buffer area, so do not trim the read_nonraw() length by the caller's size parameter. 3) Send data ACKs when necessary in read_nonraw(). 4) In read_nonraw() when we get a pure ACK, advance the RX head unconditionally past it. 5) Provide the ACKID field in the ldcdgb() packet dump in read_nonraw(). This helps debugging stream mode LDC channel problems. 6) Decrease verbosity of rx_data_wait() so that it is more useful. A debugging message each loop iteration is too much. 7) In process_data_ack() stop the loop checking when we hit lp->tx_tail not lp->tx_head. 8) Set the seqid field properly in send_data_nack().

Virtual devices on Sun Logical Domains are built on top of a virtual channel framework. This, with help of hypervisor interfaces, provides a link layer protocol with basic handshaking over which virtual device clients and servers communicate. Built on top of this is a VIO device protocol which has it's own handshaking and message types. At this layer attributes are exchanged (disk size, network device addresses, etc.) descriptor rings are registered, and data transfers are triggers and replied to. Signed-off-by: NDavid S.
