| | | | | | | | | | | | | | This patch builds on the infrastructure introduced in the patches that allow user specification of GRU blades & chiplets for context allocation.

* gru: fix istatus race in GRU tlb dropinJack Steiner2009-12-161-29/+20
| | | | | | | | | | | | | | | | | | TLB dropins require updates to the CBR instruction istatus field. This is needed to resolve race conditions in the chip. The code currently uses the user address of the CBR. This works but opens up additional endcases related to stealing of contexts and accessing the CBR from tasks that do not have access to the user address space. (Some of this non-user task access is debug code that is not currently being pushed to the community). User CBRs are also directly accessible using the kernel mapping of the CBR. Change the TLB dropin code to use the the kernel mapping of the CBR.

* x86: uv: XPC receive message reuse triggers invalid BUG_ON()Robin Holt2009-12-161-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was a difficult bug to trip. XPC was in the middle of sending an acknowledgement for a received message. In xpc_received_payload_uv(): . ret = xpc_send_gru_msg(ch->sn.uv.cached_notify_gru_mq_desc, msg, sizeof(struct xpc_notify_mq_msghdr_uv)); if (ret != xpSuccess) XPC_DEACTIVATE_PARTITION(&xpc_partitions[ch->partid], ret); msg->hdr.msg_slot_number += ch->remote_nentries; at the point in xpc_send_gru_msg() where the hardware has dispatched the acknowledgement, the remote side is able to reuse the message structure and send a message with a different slot number. This problem is made worse by interrupts. The adjustment of msg_slot_number and the BUG_ON in xpc_handle_notify_mq_msg_uv() which verifies the msg_slot_number is consistent are only used for debug purposes. Since a fix for this that preserves the debug functionality would either have to infringe upon the payload or allocate another structure just for debug, I decided to remove it entirely.

* X86: uv: xpc_make_first_contact hang due to not accepting ACTIVE stateRobin Holt2009-12-161-1/+2
| | | | | | | | | | | | | | | | | Many times while the initial connection is being made, the contacted partition will send back both the ACTIVATING and the ACTIVE remote_act_state changes in very close succescion. The 1/4 second delay in the make first contact loop is large enough to nearly always miss the ACTIVATING state change. Since either state indicates the remote partition has acknowledged our state change, accept either.

* x86: uv: update XPC to handle updated BIOS interfaceRobin Holt2009-12-163-16/+47
| | | | | | | | | | | | | | | | | The UV BIOS has moved the location of some of their pointers to the "partition reserved page" from memory into a uv hub MMR. The GRU does not support bcopy operations from MMR space so we need to special case the MMR addresses using VLOAD operations. Additionally, the BIOS call for registering a message queue watchlist has removed the 'blade' value and eliminated the structure that was being passed in. This is also reflected in this patch.

| * | | | sysctl: Drop & in front of every proc_handler.Eric W. Biederman2009-11-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For consistency drop & in front of every proc_handler. Explicity taking the address is unnecessary and it prevents optimizations like stubbing the proc_handlers to NULL.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes handling of uv hub irq affinity. IRQs with ALL or NODE affinity can be routed to cpus other than their originally assigned cpu. Those with CPU affinity cannot be rerouted.

| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Writes may take some time on EEPROMs, so for consecutive writes, we already have a loop waiting for the EEPROM to become ready. Use such a loop for reads, too, in case somebody wants to immediately read after a write.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not a single line of actual code in the function was really fundamentally correct. Problems ranged from lack of proper range checking, to removing the last character written (which admittedly is usually '\n'), to not accepting hex numbers even though the 'show' routine would show the data in that format. This tries to do better.
