QNX Software Development Platform 6.5.0 Service Pack 1

• We've added the following cam option:
  • resmgr=m:l:h:d

  as well as the following interface-specific options:

  • altstatus
  • enable
  • iwaitnbsy=ms
  • resets=num
  • tmem=name
  • vaddr
  • verbose=level

  and the following device-specific options:

  • apm_level=level
  • drdy=mode
  • nobmstr
  • rahead=state
  • spinup=time
  • verbose=level

  The following options are obsolete:

  • noconcurrent (interface-specific)
  • lba48 (device-specific)

  The wcache device-specific option takes a value of on or off.

• We've described how the driver chooses the connection mode.

heads=num

Specify the number of heads (default 1).

tracks=num

Specify the number of sectors per track (default 1).

• nodaemon — don't daemonize
• priority=prio — set the working priority of the internal pulse.

• debug=[rx|tx|intr|all|none] — write raw URB data to slogger
• drt=num — data ready timeout
• name=name — the basename for the pathname entry
• retry=num — the number of retries if a status of USBD_STATUS_DEV_NOANSWER is given
• -o nodaemon — don't daemonize

• -A — when registering the path names for the partitions with resmgr_attach(), use the _RESMGR_FLAG_AFTER flag to force the path to be resolved after others with the same pathname at the same mountpoint.
• -L limit — the number of retries to make if the physical flash erase functions for a unit fails. The default is 0.

The following options are new:

• -D — enable automatic detection of ECC mode.
• -x — enable software ECC mode.

The arguments to the -t option have changed. You can now specify the high water, low water, and maximum number of threads for the driver's thread pool.

int_mod=N

The interrupt moderation value. The default is 20000 interrupts/sec; a value of zero disables interrupt moderation.

force_link

Force the link speed/duplex. The default is to autonegotiate the advertised speed/duplex.

max_read=N

The maximum PCIe read request size. N must be 128, 256, 512, 1024, 2048, or 4096 bytes.

tx_reap=N

The maximum number of transmit descriptors to reap. The default is 64.

Other changes include:

• The default number of receive descriptors is now 512, and the maximum is 4096.
• The default number of transmit descriptors is now 4096, and so is the maximum.

ports=port:port...

Set the enumeration order of each root port. Use colons to separate the port numbers.

memory=name

Use the specified typed memory for DMA descriptors (endpoint descriptor, transfer descriptors, and so on).

isoptd=num

Restrict the number of isoch frames each TD can transfer (default 8).

memory=name

Use the specified typed memory for DMA descriptors (endpoint descriptor, transfer descriptors, and so on).

• The following options are new:

  -H

  Don't apply the hostname to the local system, whether supplied by the server or via the -h option. In the latter case, the hostname is still sent to the server via option 12.

  -k

  Don't set the CS_DOMAIN (Domain Name) configuration string if you're using the -m option.

• The dhcp.client utility now runs an optional script, /etc/dhcp/dhcp-check, that takes the environment as dhcp-up does, but returns a value indicating if the configuration is acceptable (0 means OK; other values result in a DHCPDECLINE).

• -P — dump the physical memory mappings.
• -t — dump the stack of the errant thread only, instead of for all threads.

We've documented the following card options that apply to all sound drivers:

unit=number

The card number to mount the driver as.

dindex=number

The device number that additional following options apply to.

play_name=name

The symbolic name to assign to the PCM playback device.

cap_name=name

The symbolic name to assign to the PCM capture device.

as well as the following memory (-m) options:

pool_size=kbytes

The size of the DMA memory pool to create, in KB.

pool_name=string

The name of a shared memory object to map and use as DMA memory pool. This object must be physically contiguous memory.

and the following global (-o) options:

intr_thread_prio=priority

Set the priority of the interrupt service threads. The default is 50.

sw_mixer_rate=[FAHQ|FA|Lvalue]

Set the method of selecting the sampling frequency used by the PCM software mixing device if the underlying hardware device supports multiple rates.

sw_mixer_samples=num

Adjust the fragment size used by the software mixer to something other than the default of 2048 samples.

• There's a new -P option that you can use to specify the priority to use for io-pkt's main thread. The default is 21.
• The TCP/IP module supports the following new options:

  pfil_ipsec

  (io-pkt-v4-hc and io-pkt-v6-hc only) Run packet filters on packets before encryption.

  timer_pulse_prio=priority

  The priority to use for the timer pulse.

-e priority

Set the priority of the enumeration thread.

-r num

Set the number of enumeration retries (default 3).

-t memory=name

Set the typed-memory name (default none, using sysram).

• The documentation now shows how to load this module when you start io-pkt-*.
• By default, AutoIP no longer uses routes to direct the link-local network to use the routable IP address of the interface, nor does it route by default to the link-local IP address. If the old routing behavior is necessary, use the old option. Using routing this way was problematic depending on the peer configuration, as well as when multiple interfaces were present. The force option now has no effect unless you've also specified old.

• -p priority — run at the given static priority.

We've also documented the following:

• -d — don't daemonize

• -d — don't daemonize

• scrub fragment reassemble
• scrub fragment crop
• scrub fragment drop-ovl

They're replaced by the reassemble feature, which you specify with the set reassemble command.

• The description of the Blocked column now mentions that if the blocking process is running on a remote node, the process ID is followed by @ and the node name.
• We've documented these format letters:

  C D F G L r t U u V v W w X x Y y Z z
  

  as well as the @ memory format letter, and the debug, thread, and process flags.

• If a shared object that contains text relocations is remapped as private, pidin mem now displays an exclamation mark (!) beside the name.

• -d — don't daemonize

• We've described the -save-temps option, which saves intermediate files created during compilation.
• We've added c++-header to the list of supported values for the -x option, and we've listed the extensions that are parsed to create precompiled headers.

• -m — use CLOCK_MONOTONIC instead of the default CLOCK_REALTIME as the clock source.
• -u event_id — generate a user-string trace event for all messages received.
