ipr: Increase default adapter init stage change timeout

2015-08-12T14:33:14+00:00

commit 45c44b5ff9caa743ed9c2bfd44307c536c9caf1e upstream. Increase the default init stage change timeout from 15 seconds to 30 seconds. This resolves issues we have seen with some adapters not transitioning to the first init stage within 15 seconds, which results in adapter initialization failures.

[SCSI] ipr: Fix BUG on adapter dump timeout

2011-10-20T15:19:55+00:00

If an adapter dump times out, the ipr driver will abort the dump and proceed to reset and recover the adapter. When an adapter dump completes, the work thread which is reading the adapter dump will initiate an adapter reset to recover the adapter. However, when the adapter dump gets aborted, the work thread should not initiate an adapter reset, since an adapter reset is already in progress. This fixes a case of calling pci_block_user_cfg_access overlapped, which results in a BUG. Signed-off-by: Brian King Signed-off-by: James Bottomley

[SCSI] ipr: Add support to flash FPGA and flash back DRAM images

2011-10-16T15:56:27+00:00

The write buffer command is used to download and burn new IOA FW images. The same interface can now be used to flash FPGA and flash back DRAM images. To download and flash the new images takes more than 15 minutes, so increase the write buffer command timeout to 30 minutes. The FPGA and flash back DRAM images don't have the same card_type as the IOA FW image. So, remove the sanity checking from the driver. The adapter has sanity checking and will only accept a valid image. Signed-off-by: Wayne Boyer Acked-by: Brian King Signed-off-by: James Bottomley

[SCSI] ipr: Stop reading adapter dump prematurely

2011-09-22T11:30:28+00:00

When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.

[SCSI] ipr: increase the dump size for 64 bit adapters

2011-05-01T17:09:20+00:00

Currently the size of the dump generated by the driver is limited in 4MB, which is insufficient to gather much useful data from the new 64 bit adapters. This patch makes the needed changes to increase the dump limit for the 64 bit adapters to 32MB, or even to a bigger value in the future, but keeping the current limitations for the legacy 32 bit adapters.

[SCSI] ipr: fix synchronous request flags for better performance

2011-05-01T15:16:44+00:00

In testing it was noticed that Extended Delay after Reset flag was being set for gscsi and volume set devices. This had a negative effect on performance for volume sets. The fix is to only set the flag for gscsi devices. Signed-off-by: Wayne Boyer Acked-by: Brian King Signed-off-by: James Bottomley

[SCSI] ipr: fix mailbox register definition and add a delay before reading

2010-12-21T18:23:55+00:00

The definition for the mailbox register for new adapters was incorrect. The value has been updated to the correct offset. After an adapter reset, the mailbox register on the new adapters takes a number of seconds to stabilize. A delay has been added before reading the register.

[SCSI] ipr: add definitions for a new adapter

There was an addition to the hardware roadmap that includes a new adapter. This patch adds the new definitions for the adapter. Signed-off-by: Wayne Boyer Acked-by: Brian King Signed-off-by: James Bottomley
