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

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

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.Signed-off-by: Brian King

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.Signed-off-by: Kleber Sacilotto de Souza

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

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

A change in the hardware design of the chip for the new adapters changes the
default endianness of MMIO operations. This patch adds a register definition
which when written to with a predefined value will change the endianness
back to what the driver expects.This patch also fixes two problems found during testing.
First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only
reserved one byte. The correct amount to reserve is 2 bytes.Second, the reserved field of the ipr_hostrcb64_error structure only reserved
2 bytes. The correct amount to reserve is 16 bytes.Signed-off-by: Wayne Boyer

This patch adds a reboot notifier that will issue a shutdown prepare command

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).Signed-off-by: Brian King
