This patch contains additional structure and function definition changes

by the previous 4 patches.
 - structure and function definition changes to header files as a result
   of Ethport, Enet, IOCEth, Tx, Rx redesign.
 - ethtool changes to use new enet function and definitions
 - Set number of Tx and Rx queues bassed on underlying hardware. Define
   separate macros for maximum and supported numbers of Tx and Rx queues
   based on underlying hardware. Take VLAN header into account for MTU
   calculation. Default to INTx mode when pci_enable_msix() fails. Set a
   bit in Rx poll routine, check and wait for that bit to be cleared in
   the cleanup routine before proceeding.
 - The TX and Rx coalesce settings are programmed in steps of 5 us. The value
   that are not divisible by 5 are rounded to the next lower number. This was
   causing the value os 1 to 4 to be rounded to 0, which is an invalid setting.
   When creating Rx and Tx object, we are currently assigning the default
   values of Rx and Tx coalescing_timeo. If these values are changed in the
   driver to a different value, the change is lost during such operations as

   path setup. In the old design, setting up Txqs, Rxqs were done in the driver.
   With the new design, most of the hardware setup steps for the Txq, Rxqs are
   moved to FW. Host driver issues commands to FW through the message queue to
   setup/teardown tx, rx data path. FW performs necessary steps and responds
   back to the driver with a status.

   objects have changed significantly. Instead of doing the raw register access,
   these state machines mostly send a command to FW and wait for response and

The inode structure layout is largely random, and some of the vfs paths
really do care.  The path lookup in particular is already quite D$
intensive, and profiles show that accessing the 'inode->i_op->xyz'

We already optimized the dcache to not unnecessarily load the d_op
structure for members that are often NULL using the DCACHE_OP_xyz bits
in dentry->d_flags, and this does something very similar for the inode
ops that are used during pathname lookup.

It also re-orders the fields so that the fields accessed by 'stat' are
together at the beginning of the inode structure, and roughly in the
order accessed.

The effect of this seems to be in the 1-2% range for an empty kernel
"make -j" run (which is fairly kernel-intensive, mostly in filename
lookup), so it's visible.  The numbers are fairly noisy, though, and

exofs: ios: Move to a per inode components & device-table

Exofs raid engine was saving on memory space by having a single layout-info,
single pid, and a single device-table, global to the filesystem. Then passing
a credential and object_id info at the io_state level, private for each
inode. It would also devise this contraption of rotating the device table
view for each inode->ino to spread out the device usage.

This is not compatible with the pnfs-objects standard, demanding that
each inode can have it's own layout-info, device-table, and each object
component it's own pid, oid and creds.

So: Bring exofs raid engine to be usable for generic pnfs-objects use by:

* Define an exofs_comp structure that holds obj_id and credential info.

* Break up exofs_layout struct to an exofs_components structure that holds a
  possible array of exofs_comp and the array of devices + the size of the
  arrays.

* Add a "comps" parameter to get_io_state() that specifies the ids creds
  and device array to use for each IO.

  This enables to keep the layout global, but the device-table view, creds
  and IDs at the inode level. It only adds two 64bit to each inode, since
  some of these members already existed in another form.

* ios raid engine now access layout-info and comps-info through the passed
  pointers. Everything is pre-prepared by caller for generic access of
  these structures and arrays.

At the exofs Level:

* Super block holds an exofs_components struct that holds the device
  array, previously in layout. The devices there are in device-table
  order. The device-array is twice bigger and repeats the device-table
  twice so now each inode's device array can point to a random device
  and have a round-robin view of the table, making it compatible to
  previous exofs versions.

* Each inode has an exofs_components struct that is initialized at
  load time, with it's own view of the device table IDs and creds.
  When doing IO this gets passed to the io_state together with the
  layout.

While preforming this change. Bugs where found where credentials with the
wrong IDs where used to access the different SB objects (super.c). As well
as some dead code. It was never noticed because the target we use does not
check the credentials.

exofs: Move exofs specific osd operations out of ios.c

ios.c will be moving to an external library, for use by the
objects-layout-driver. Remove from it some exofs specific functions.

Also g_attr_logical_length is used both by inode.c and ios.c
move definition to the later, to keep it independent

13 years agoexofs: Add offset/length to exofs_get_io_state
Boaz Harrosh [Tue, 16 Nov 2010 18:09:58 +0000 (20:09 +0200)]
exofs: Add offset/length to exofs_get_io_state

In future raid code we will need to know the IO offset/length
and if it's a read or write to determine some of the array
sizes we'll need.

So add a new exofs_get_rw_state() API for use when
writeing/reading. All other simple cases are left using the
old way.

The major change to this is that now we need to call
exofs_get_io_state later at inode.c::read_exec and
inode.c::write_exec when we actually know these things. So this
patch is kept separate so I can test things apart from other
changes.
