* V4L/DVB (5593): Budget-ci: Fix tuning for TDM 1316 (160..200 MHz)Oliver Endriss2007-05-09
| | | | | | | | | | | | | | | | | | | Revert changeset http://linuxtv.org/hg/v4l-dvb?cmd=changeset;node=e7c424bbf9aa;style=gitweb Petri Helin found that this changeset broke tuning: 'Well, after going through the changes that might have had effect on tuning, I found out the one which had caused this problem. I do not know the actual reason behind the change, but the changelog says that it was meant to "Fix TD1316 tuner for DVBC". But at least in my case it seams to have broken the tuner instead.'

* V4L/DVB (5592): DMA: Correctly free resources on error, sync PCI streamed dataJon Burgess2007-05-09
| | | | | | | | | | | | | | | | | | | I added saa7146_vmalloc_destroy_pgtable() which frees the resources allocated by saa7146_vmalloc_build_pgtable() and updated the callers in budget-core.c and av7110.c. I have also been through the updated functions and updated the error paths to ensure they free all allocated resources on error. I also realised that there are other callers to saa7146_pgtable_free() which did not have any sg DMA mapped so it seems wrong to add the pci_unmap_sg() into that function. Instead I created saa7146_vmalloc_destroy_pgtable() to do this. Also included in this patch are the previous fixes for pci_unmap_sg() and syncing the PCI streamed data to work with a SWIOTLB and match the requirements documented in DMA-API.txt.

* V4L/DVB (5578): Workaround for bad hardare/firmware on some pluto2 devicesholger@muscate-magnussen.de2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | pluto2_driver: Workaround for pluto2 card reporting wrong number of received packets and flooding system with interrupts. This patch constitutes a workaround for a hardware/firmware problem of the pluto2-based card (e.g., Satelco EasyWatch). It can happen in rare cases that the card gets into a mode where it always reports back a number of received packets (nbpackets) which is larger than the maximum permissible number of packets (TS_DMA_PACKETS). The workaround that is already in the driver in function pluto_dma_end reports back zero received packets. In spite of the (in reality) zero received packets the card continues to generate interrupts at a very high rate, which can effectively stall the system. The patch resets the TS logic, which puts the card back into normal operations.

* V4L/DVB (5575): Pvrusb2: Implement ability to disable IR receiverMike Isely2007-05-09
| | | | | | | | | | | | | | Anyone using multiple PVR USB2 devices really only want one of them acting as the actual IR receiver. Implemented here is a new per-instance module option (ir_mode) which is a flag to enable the IR receiver. The default is enabled.

* V4L/DVB (5573): Pvrusb2: kill unnecessary attribute->ownerTejun Heo2007-05-09
| | | | | | | | | | | | | | | | | | | | | | | sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Must clear adapter failed flag if an fsf request times out. This is necessary because on link down situations the failed flags gets set but the QDIO queues are still up. Since an adapter reopen will be skipped if the failed flag is set an adapter_reopen that is issued on fsf request timeout has no effect if the local link is down. Might lead to locked up system if the SCSI stack is waiting for abort completion.

| * | [SCSI] zfcp: Fix deadlock between zfcp ERP and SCSIChristof Schmitt2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SCSI stack requires low level drivers to register and unregister devices. For zfcp this leads to the situation where zfcp calls the SCSI stack, the SCSI tries to scan the new device and the scan SCSI command fails. This would require the zfcp erp, but the erp thread is already blocked in the register call. The fix is to make sure that the calls from the ERP thread to the SCSI stack do not block the ERP thread. In detail: 1) Use a workqueue to avoid blocking of the scsi_scan_target calls. 2) When removing a unit make sure that no scsi_scan_target call is pending. 3) Replace scsi_flush_work with scsi_target_unblock. This avoids blocking and has the same result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

Status information and data that is being read from the device is written to this memory by the hardware. After that, the hardware signals this via the response queue and zfcp continues processing. Now, if zfcp detects that there is a signal for an incoming response from the hardware, but there is no outstanding request for that request id, then some memory that can be in use anywhere in the system has just been overwritten. This should never happen, but if it does, stop the system with a panic.

| * | [SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllersSalyzyn, Mark2007-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kexec patch introduced a superfluous (and otherwise inert) reset of some adapters. The register can have a hardware default value that has zeros for the undefined interrupts. This patch refines the test of the interrupt enable register to focus on only the interrupts that affect the driver in order to detect if an incomplete shutdown of the Adapter had occurred (kdump).
