* RDMA/nes: Fix Xansation test crash on cm_node ref_countFaisal Latif2009-12-101-1/+16
| | | | | | | | | | | | | | | | While running a Xansation test, an active side node crashed. The problem started on the passive side, which generated an STtag that was 0. The passive side sent a TERMINATE instead of an MPA REJECT msg. The active side, receives TERMINATE and sends connect_err() and set the cm_node state to CLOSED. The passive side sends FIN + ACK after TERMINATE. Active side ends up in handle_ack_pkt() and send_reset(). send_reset() consumes 1 cm_node's ref_count. Because the cm_node is in CLOSED state, which means that cm_node will be destroyed after completion of the connect_err() indication, CM will crash after send_reset().

* RDMA/nes: Abnormal listener exit causes loopback node crashFaisal Latif2009-12-101-13/+3
| | | | | | | | | | | When the listener is destroyed for a loopback connection, the listener node gets a reset event. This causes a crash as the listener is not expecting a reset event. Code review of cm_event_reset() during debugging showed the cm_id ref count is incremented after calling its event handler and not before.

* RDMA/nes: Fix crash in nes_accept()Faisal Latif2009-12-102-28/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While running IMP_EXT's window test, we saw a crash in nes_accept(). Here is the sequence of what happened: (1) In MVAPICH2, connect request is received for port #0. FIX: Add a nes_connect() check to make sure local or remote tcp port is not 0. (2) Remote node's (passive) TCP stack sends a reset when it gets a connect request because of port = 0. Active side set the connect error to IW_CM_EVENT_STATUS_REJECTED when it received the RST from remote node. FIX: The corect error code is -ECONNRESET. (3) Wrong error code of IW_CM_EVENT_STATUS_REJECTED causes the core to destroy its listener ports. Here there are connections that may have sent an MPA request up and waiting for accept or reject. But the listener and its cm_nodes have been freed already causing the crash noticed. FIX: The cm_node is freed only if its state is not NES_CM_STATE_MPAREQ_RCVD. If cm_node's state is NES_CM_STATE_MPAREQ_RCVD then its new state is set to NES_CM_STATE_LISTENER_DESTROYED and it is not freed. When nes_accept() or nes_reject() is received, its state is checked for NES_CM_STATE_LISTENER_DESTROYED and in this case the cm_node is freed and error is returned.

| | | | | | | | | | During testing of REJECT connection error handling, we saw that the cm_id resources are not released. When the retransmit timer expires, we need to send a reset message to remote node before issuing the ABORTED event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable framebuffer compression on a g4x, we not only need the buffer to tiled (X only), we also need to hold a fence register for the buffer. Currently we only install a fence register for pre-i965s when setting up the scanout buffer. Rather than adding some convoluted logic to g4x_enable_fbc() to acquire a fence register, and perhaps to g4x_disable_fbc() to release it again, we can extend the acquisition during setup to all chipsets.

Border should be used when in VGA centered (un-scaled) mode or when scaling a 4:3 source image to a wide screen panel (typical 16:9). So when the LVDS scaling is used, decide whether the LVDS_BORDER should be enabled or not according to the current scaling mode.

But the optimization get abused. Considering thread a, b, which work on one file. a reads sectors s, s+2, s+4, ...; b reads sectors s+1, s+3, s +5, ... Both a and b are sequential read, so they can open idle window. a reads a sector s and goes to idle window and wakeup b. b reads sector s+1, since in current implementation, cfq_should_preempt() thinks a and b are cooperators, b will preempt a. b then reads sector s+1 and goes to idle window and wakeup a. for the same reason, a will preempt b and reads s+2. a and b will continue the circle. The circle will be very long, and a and b will occupy whole disk queue. Other applications will nearly have no chance to run. Fix this limiting coop preempt until a queue is scheduled normally again.
