wl1271: Add structure for firmware configuration values

In order to make the firmware configuration more manageable, collect
hardcoded configuration values into one data structure, and set default values
there.

Add the SoftGemini BT/WLAN coex paramters into the config structure.

11 years agowl1271: Workaround for reference clock setting on boot.
Juuso Oikarinen [Tue, 13 Oct 2009 09:47:38 +0000]
wl1271: Workaround for reference clock setting on boot.

If the 38.4MHz reference clock is configured to the firmware, it crashes
on boot. Configuring an experimental 38.4MHz in XTAL mode allows the
firmware to boot, and everything appears to work.

11 years agoiwlwifi: use paged Rx
Zhu Yi [Fri, 9 Oct 2009 09:19:45 +0000]
iwlwifi: use paged Rx

This switches the iwlwifi driver to use paged skb from linear skb for Rx
buffer. So that it relieves some Rx buffer allocation pressure for the
memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for
Rx buffer. Due to the trailing skb_shared_info in the skb->data,
alloc_skb() will do the next order allocation, which is 16K bytes. This
is suboptimal and more likely to fail when the system is under memory
usage pressure. Switching to paged Rx skb lets us allocate the RXB
directly by alloc_pages(), so that only order 1 allocation is required.

It also adjusts the area spin_lock (with IRQ disabled) protected in the
tasklet because tasklet guarentees to run only on one CPU and the new
unprotected code can be preempted by the IRQ handler. This saves us from
spawning another workqueue to make skb_linearize/__pskb_pull_tail happy
(which cannot be called in hard irq context).

Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb
for all the management frames and software decryption or defragmentation
required data frames before handed to mac80211. For all the other frames,
we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211
to handle them properly.

11 years agoiwlwifi: turn off device when not used.
Ben Cahill [Fri, 9 Oct 2009 20:20:20 +0000]
iwlwifi: turn off device when not used.

In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user
no longer wants device active), device has not been going into low power state
via __iwl_down().  apm_ops.reset() does not put device into low power state;
instead it resets the device, then puts it into a powered-up state ready to be
re-loaded with uCode and re-started.  This has needlessly warmed up user's
laptops and drained batteries.

With current architecture in which mac80211 controls device up/down (including
resetting device after firmware errors), there is no need for apm_ops.reset()
any more; apm_ops.reset() is basically a combination of apm_ops.stop() and
apm_ops.init().

Instead, __iwl_down() now unconditionally places the device into a low-power
state via apm_ops.stop(). Device may be re-started via __iwl_up() calling
apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors),
but in the meantime, device will stop wasting energy.

Note that, even in this low power state, if driver re-enables interrupts,
the device retains the ability to sense the hardware RF-KILL switch, and
(except for 3945) interrupt the host when it changes.

Ben Cahill [Fri, 9 Oct 2009 20:20:19 +0000]
iwl3945: update iwl3945_apm_init()

Update iwl3945_apm_init() to set up device registers in sequence most recently
recommended by factory.

Add resets for APMG interrupts and radio chip, formerly done only in
iwl3945_apm_reset(); moving them here assures that apm_init() will do
a complete job of preparing hardware not only after platform boot,
but also after apm_stop() has executed (due to rfkill, ifconfig down,
driver unload, etc.).  This is in preparation to completely remove apm_reset().

Add some comments.

sfc: Remove versioned bitfield macros

These macros are not extensible to more than two NIC types without
repetition of register definitions, and they are only used to deal
with a few fields in RX_CFG_REG and global events which moved between
Falcon rev A1 and B0.

Therefore:
- Move RX_CFG_REG initialisation into its own function which tests the
  NIC revision just once
- Explicitly test the NIC revision when checking the RX_RECOVERY flag in
  global events
- Merge definitions of RX_XOFF_MAC_EN flag, which did not move
- Remove the macro definitions
