2008-07-01powerpc/mpc5200: Fix lite5200b suspend/resumeTim Yamin
Suspend/resume ("echo mem > /sys/power/state") does not work with vanilla kernels -- the system does not suspend correctly and just hangs. This patch fixes this so suspend/resume works: 1) of_iomap does not map the whole 0xC000 of the MPC5200 immr so saving registers does not work. 2) PCI registers need to be saved and restored.

2008-06-16powerpc/spufs: fix missed stop-and-signal eventLuke Browning
There is a delay in the transition to the stopped state for class 2 interrupts. In some cases, the controlling thread detects the state of the spu as running, and goes back to sleep resulting in a hung application as the event is missed. This change detects the stop condition and re-generates the wakeup event after a context save. Signed-off-by: Luke Browning <lukebrowning@us.ibm.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

2008-06-16powerpc/spufs: remove class_0_dsisr from spu exception handlingLuke Browning
According to the CBEA, the SPU dsisr is not updated for class 0 exceptions. spu_stopped() is testing the dsisr that was passed to it from the class 0 exception handler, so we return a false positive here. This patch cleans up the interrupt handler and erroneous tests in spu_stopped. It also removes the fields from the csa since it is not needed to process class 0 events.

2008-06-09[POWERPC] 85xx: MPC85xx MDS - Unconditionally select PHYLIB for board fixupsKumar Gala
The MPC85xx MDS board requires some board level tweaks of the PHYs that either the eTSEC (gianfar) or UCC ethernet controllers are connected to. Its possible to build the phylib as a module, however this breaks the board level fix ups because phy_read and phy_write are not available if we build as a module. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in MPC85xx MDS support. This was determined to be the easiest soultion even though it prevents the user from removing PHYLIB support if they decide they don't want it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-05-05[POWERPC] spufs: handle faults while the context switch pending flag is setLuke Browning
Currently, page fault handlers don't issue a mfc restart if the context switch pending flag is set, which can leave us with a hanging DMA after a context restore. This patch introduces fault pending flag that is set by the fault handler and read by the context switch code, so that the latter can add the restart bit at the right spot, after it has successfuly saved the state of the mfc control register.

2008-05-05[POWERPC] spufs: try to route SPU interrupts to local nodeLuke Browning
Currently, we re-route SPU interrupts to the current cpu, which may be on a remote node. In the case of time slicing, all spu interrupts will end up routed to the same cpu, where the spusched_tick occurs. This change routes mfc interrupts to the cpu where the controlling thread last ran, provided that cpu is on the same node as the spu (otherwise don't reroute interrupts). This should improve performance and provide a more predictable environment for processing spu exceptions. In the past we have seen concurrent delivery of spu exceptions to two cpus. This eliminates that concern. Signed-off-by: Luke Browning <lukebr@linux.vnet.ibm.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
2008-05-05[POWERPC] spufs: set SPU_CONTEXT_SWITCH_PENDING before synchronising SPU irqsLuke Browning
synchronize_irq() provides the serialization for SPU_CONTEXT_SWITCH_PENDING which is read with a simple load. This routine guarantees that the relevant interrupt handlers are not running, so that the next time they do run they will see the update memory value. This must be done correctly so that exception handling code does not restart the mfc in the middle of a context switch while we are trying to atomically stop it and save state.

Currently, we update the SPU master run control bit (ie, spu_enable_spu) in spufs_run_spu before we grab the context mutex.

2008-05-05[POWERPC] spufs: fix save of mfc_cntl registerJeremy Kerr
Currently, we can introduce invalid entries into the MFC queues: 1) context starts a DMA 2) context gets scheduled out during a DMA - kernel saves MFC queue to CSA - kernel saves 0x0 in csa->mfc_control_RW 3) context gets scheduled in - csa->mfc_control[Q] ('queues empty') isn't set, so DMA queues are restored from the CSA 4) context's DMA is completed 5) context gets scheduled out again, no DMA occuring this time - kernel sees that MFC_CNTL[Q] ('queues empty') is set, so doesn't touch saved queue data in CSA - kernel saves 0x0 in csa->mfc_control_RW 6) context gets scheduled in - csa->mfc_control[Q] ('queues empty') isn't set (we saved is as 0!), so DMA queues are restored from the CSA In this last restore, we've restored the queue status from step 2, which are now invalid. This change makes save_mfc_cntl() closer to the save/restore sequence, as specified in the CBE handbook. With changes from Luke Browning. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>

2008-05-05[POWERPC] cell: Fix lost interrupts due to fasteoi handlerJeremy Kerr
We may currently lose interrupts during SPE context switch, as we alter the INT_Route register. Because the IIC uses a per-thread priority status, changing the interrupt routing to a different thread means that the IRQ is no longer masked by the priority status, so we end up with two fasteoi IRQ handlers executing for the one irq_desc. The fasteoi handler doesn't handle multiple IRQs, so drops the second one. Fix this by using our own flow handler. This is based on handle_edge_irq, but issues an eoi after IRQs are handled, and doesn't do any mask/unmasking. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
