sdbfs/lib: add flag ZEROBASED and remove verbose argument to register() · 290089ef


Adding ZEROBASED allows the lm32 to enumerate fpga cores without
prviding a specific read() method.

Removing "verbose" as an argument to sdbfs_dev_create (and allowing
the user to set it in fs->flags) is a minor cleanup, though incompatible.
Userspace is fixed to deal with this incompatibility.

This is a slight incompatibility, but it's worh doing.

- pcie_wb: turn on/off non-MSI interrupts as required · 2cbb743f
  Wesley W. Terpstra authored 10 years ago
```
Usually our cards are used in MSI mode. On older motherboards, they
can fall back to classic interrupt generation. However, then the
interrupt enable register in the card must be turned on.
