+/* NVIDIA context programs handle a number of other conditions which are
+ * not implemented in our versions. It's not clear why NVIDIA context
+ * programs have this code, nor whether it's strictly necessary for
+ * correct operation. We'll implement additional handling if/when we
+ * discover it's necessary.
+ *
+ * - On context save, NVIDIA set 0x400314 bit 0 to 1 if the "3D state"
+ * flag is set, this gets saved into the context.
+ * - On context save, the context program for all cards load nsource
+ * into a flag register and check for ILLEGAL_MTHD. If it's set,
+ * opcode 0x60000d is called before resuming normal operation.
+ * - Some context programs check more conditions than the above. NV44
+ * checks: ((nsource & 0x0857) || (0x400718 & 0x0100) || (intr & 0x0001))
+ * and calls 0x60000d before resuming normal operation.
+ * - At the very beginning of NVIDIA's context programs, flag 9 is checked
+ * and if true 0x800001 is called with count=0, pos=0, the flag is cleared
+ * and then the ctxprog is aborted. It looks like a complicated NOP,
+ * its purpose is unknown.
+ * - In the section of code that loads the per-vs state, NVIDIA check
+ * flag 10. If it's set, they only transfer the small 0x300 byte block
+ * of state + the state for a single vs as opposed to the state for
+ * all vs units. It doesn't seem likely that it'll occur in normal
+ * operation, especially seeing as it appears NVIDIA may have screwed
+ * up the ctxprogs for some cards and have an invalid instruction
+ * rather than a cp_lsr(ctx, dwords_for_1_vs_unit) instruction.
+ * - There's a number of places where context offset 0 (where we place
+ * the PRAMIN offset of the context) is loaded into either 0x408000,
+ * 0x408004 or 0x408008. Not sure what's up there either.
+ * - The ctxprogs for some cards save 0x400a00 again during the cleanup
+ * path for auto-loadctx.

-config DST
- tristate "Distributed storage"
- depends on NET && CRYPTO && SYSFS && BLK_DEV
- select CONNECTOR
- ---help---
- DST is a network block device storage, which can be used to organize
- exported storage on the remote nodes into the local block device.
-
- DST works on top of any network media and protocol; it is just a matter
- of configuration utility to understand the correct addresses. The most
- common example is TCP over IP, which allows to pass through firewalls and
- create remote backup storage in a different datacenter. DST requires
- single port to be enabled on the exporting node and outgoing connections
- on the local node.
-
- DST works with in-kernel client and server, which improves performance by
- eliminating unneded data copies and by not depending on the version
- of the external IO components. It requires userspace configuration utility
- though.
-
- DST uses transaction model, when each store has to be explicitly acked
- from the remote node to be considered as successfully written. There
- may be lots of in-flight transactions. When remote host does not ack
- the transaction it will be resent predefined number of times with specified
- timeouts between them. All those parameters are configurable. Transactions
- are marked as failed after all resends complete unsuccessfully; having
- long enough resend timeout and/or large number of resends allows not to
- return error to the higher (FS usually) layer in case of short network
- problems or remote node outages. In case of network RAID setup this means
- that storage will not degrade until transactions are marked as failed, and
- thus will not force checksum recalculation and data rebuild. In case of
- connection failure DST will try to reconnect to the remote node automatically.
- DST sends ping commands at idle time to detect if remote node is alive.
-
- Because of transactional model it is possible to use zero-copy sending
- without worry of data corruption (which in turn could be detected by the
- strong checksums though).
-
- DST may fully encrypt the data channel in case of untrusted channel and implement
- strong checksum of the transferred data. It is possible to configure algorithms
- and crypto keys; they should match on both sides of the network channel.
- Crypto processing does not introduce noticeble performance overhead, since DST
- uses configurable pool of threads to perform crypto processing.
-
- DST utilizes memory pool model of all its transaction allocations (it is the
- only additional allocation on the client) and server allocations (bio pools,
- while pages are allocated from the slab).
-
- At startup DST performs a simple negotiation with the export node to determine
- access permissions and size of the exported storage. It can be extended if
- new parameters should be autonegotiated.
-
- DST carries block IO flags in the protocol, which allows to transparently implement
- barriers and sync/flush operations. Those flags are used in the export node where
- IO against the local storage is performed, which means that sync write will be sync
- on the remote node too, which in turn improves data integrity and improved resistance
- to errors and data corruption during power outages or storage damages.
