7 years agoregmap: Add generic non-memory mapped register access API
Mark Brown [Wed, 11 May 2011 17:59:58 +0000]
regmap: Add generic non-memory mapped register access API

There are many places in the tree where we implement register access for
devices on non-memory mapped buses, especially I2C and SPI. Since hardware
designers seem to have settled on a relatively consistent set of register
interfaces this can be effectively factored out into shared code.  There
are a standard set of formats for marshalling data for exchange with the
device, with the actual I/O mechanisms generally being simple byte
streams.

We create an abstraction for marshaling data into formats which can be
sent on the control interfaces, and create a standard method for
plugging in actual transport underneath that.

This is mostly a refactoring and renaming of the bottom level of the
existing code for sharing register I/O which we have in ASoC. A
subsequent patch in this series converts ASoC to use this.  The main
difference in interface is that reads return values by writing to a
location provided by a pointer rather than in the return value, ensuring
we can use the full range of the type for register data.  We also use
unsigned types rather than ints for the same reason.

As some of the devices can have very large register maps the existing
ASoC code also contains infrastructure for managing register caches.
This cache work will be moved over in a future stage to allow for
separate review, the current patch only deals with the physical I/O.

7 years agovirtio: expose for non-virtualization users too
Ohad Ben-Cohen [Tue, 5 Jul 2011 14:06:14 +0000]
virtio: expose for non-virtualization users too

virtio has been so far used only in the context of virtualization,
and the virtio Kconfig was sourced directly by the relevant arch
Kconfigs when VIRTUALIZATION was selected.

Now that we start using virtio for inter-processor communications,
we need to source the virtio Kconfig outside of the virtualization
scope too.

Moreover, some architectures might use virtio for both virtualization
and inter-processor communications, so directly sourcing virtio
might yield unexpected results due to conflicting selections.

The simple solution offered by this patch is to always source virtio's
Kconfig in drivers/Kconfig, and remove it from the appropriate arch
Kconfigs. Additionally, a virtio menu entry has been added so virtio
drivers don't show up in the general drivers menu.

This way anyone can use virtio, though it's arguably less accessible
(and neat!) for virtualization users now.

Note: some architectures (mips and sh) seem to have a VIRTUALIZATION
menu merely for sourcing virtio's Kconfig, so that menu is removed too.

Blackfin: dpmc: don't save/restore scratch registers

The Blackfin C ABI says we do not need to save/restore R0-R3 and P0-P2
as they are available as scratch registers.  So don't bother.

Re-architect how we save/restore the gpio/port logic that only pertains

Mike Frysinger [Mon, 27 Jun 2011 03:11:19 +0000]
Blackfin: dpmc: optimize hibernate/resume path

The current save logic used in hibernation is to do a MMR load (base +
offset) into a register, and then push that onto the stack.  Then when
restoring, pop off the stack into a register followed by a MMR store
(base + offset).  These use plenty of 32bit insns rather than 16bit,
are pretty long winded, and full of pipeline bubbles.

So, by taking advantage of MMRs that are contiguous, the multi-register
push/pop insn, and register abuse, we can shrink this code considerably.

When saving, the new logic does a lot of loads into the data and pointer
registers before executing a single multi-register push insn.  Then when
restoring, we do a single multi-register pop insn followed by a lot of
stores.  Overall, this allows us to cut the insn count by ~30%, the code
size by ~45%, and drastically reduce the register hazards that trigger
bubbles in the pipeline.

Blackfin: dpmc: do not save/restore EVT0/EVT1/EVT4 when hibernating

EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int
disable" region.  None of these are used by software (or even hardware),
so don't bother saving/restoring them when we hibernate since nothing
ever uses these in Linux (the only thing they would be useful for is
core-memory scratch, but that's just crazy talk).

8 years agonet: allow netif_carrier to be called safely from IRQ
stephen hemminger [Fri, 22 Jul 2011 12:53:56 +0000]
net: allow netif_carrier to be called safely from IRQ

As reported by Ben Greer and Froncois Romieu. The code path in
the netif_carrier code leads it to try and disable
a late workqueue to reenable it immediately
netif_carrier_on
-> linkwatch_fire_event
   -> linkwatch_schedule_work
      -> cancel_delayed_work
         -> del_timer_sync

If __cancel_delayed_work is used instead then there is no
problem of waiting for running linkwatch_event.

There is a race between linkwatch_event running re-scheduling
but it is harmless to schedule an extra scan of the linkwatch queue.

Rasesh Mody [Fri, 22 Jul 2011 08:07:45 +0000]
bna: Mboxq Flush When IOC Disabled

Change details:
 - If there is a command pending in the mailbox, bfa_ioc_mbox_queue() enqueues
   the mailbox command to a pending command queue. Entries in this queue are
   not flushed when IOC is disabled. As a result, when IOC is re-enabled again,
   the stale entries in the pending command queue are posted to the mailbox.
   When these mailbox commands are processed by the FW and responses are sent,
   unexpected  events are received by other modules' FSMs (f.e. bfa_msgq) which
   have not posted any mailbox commands after IOC was enabled.
 - Flush the pending mailbox command queue when IOC is disabled. Rename
   bfa_ioc_mbox_hbfail to bfa_ioc_mbox_flush. Call bfa_ioc_mbox_flush
   from bfa_iocpf_sm_disabled_entry()
