Helge Deller b845f66f78 parisc/pci: Switch LBA PCI bus from Hard Fail to Soft Fail mode Carlo Pisani noticed that his C3600 workstation behaved unstable during heavy I/O on the PCI bus with a VIA VT6421 IDE/SATA PCI card. To avoid such instability, this patch switches the LBA PCI bus from Hard Fail mode into Soft Fail mode. In this mode the bus will return -1UL for timed out MMIO transactions, which is exactly how the x86 (and most other architectures) PCI busses behave. This patch is based on a proposal by Grant Grundler and Kyle McMartin 10 years ago: https://www.spinics.net/lists/linux-parisc/msg01027.html Cc: Carlo Pisani <carlojpisani@gmail.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Reviewed-by: Grant Grundler <grantgrundler@gmail.com> Signed-off-by: Helge Deller <deller@gmx.de>		2018-03-27 18:52:22 +02:00

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."
