2014-04-13iwlwifi: mvm: deprecate -7 firmwareEmmanuel Grumbach1-2/+2
This firmware is not supported any more. A few code paths specific to old firmware can be removed. We can now assume that a few TLV flags are always set since we won't load firmware that didn't support the corresponding features. This will be done in a separate patch.

2014-04-06iwlwifi: pcie: don't leave the new NICs awake for commandsEmmanuel Grumbach1-0/+1
A hardware bug had been discovered on 7260 / 3160 and 7265 and the workaround for this bug is to force the NIC to stay awake as long as we have host commands in flight. This workaround has been introduced for all NICs in a previous patch: b9439491055a ("iwlwifi: pcie: keep the NIC awake when commands are in flight") In newer NICs, this bug is solved, so we can let the NIC go to sleep even when we send commands. The hardware will wake up when we increment the scheduler write pointer. Make the workaround conditional to only use it on affected hardware.

2014-03-09iwlwifi: pcie: enable LP XTAL to reduce power consumptionAlexander Bondar1-0/+4
1. Enable LP XTAL to avoid HW bug where device may consume much power if FW is not loaded after device reset. LP XTAL is disabled by default after device HW reset. Configure device's "persistence" mode to avoid resetting XTAL again when SHRD_HW_RST occurs in S3. 2. Add methods to access SHR (shared block memory space) directly from PCI bus w/o need to power up MAC HW. Shared internal registers (e.g. SHR_APMG_GP1, SHR_APMG_XTAL_CFG)can be accessed directly from PCI bus through SHR arbiter even when MAC HW is powered down. This is possible due to indirect read/write via HEEP_CTRL_WRD_PCIEX_CTRL (0xEC) and HEEP_CTRL_WRD_PCIEX_DATA (0xF4) registers. Use iwl_write32()/iwl_read32() family to access these registers. The MAC HW need not be powered up so no "grab inc access" is required. For example, to read from SHR_APMG_GP1 register (0x1DC), first, write to the control register: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 2 (read access) second, read from the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0]. To write the register, first, write to the data register HEEP_CTRL_WRD_PCIEX_DATA[31:0] and then: HEEP_CTRL_WRD_PCIEX_CTRL[15:0] = 0x1DC (offset of the SHR_APMG_GP1 register) HEEP_CTRL_WRD_PCIEX_CTRL[29:28] = 3 (write access) Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2013-12-18iwlwifi: mvm: rs: fix RTS protection being set indefinitelyEyal Shapira1-1/+0
RTS protection was turned on once aggregation was enabled but it was never turned off. Remove turning on RTS protection in the LQ command completely as TX_CMD_FLG_PROT_REQUIRE gets set in iwl_mvm_set_tx_cmd for every Tx which is part of an aggregation. This would already cause RTS protection to be used during aggregations.

Not all chips support STBC so allow this to be another config parameter per chip type. If STBC is supported then publish it in the HT caps. Since 7260/7265/3160 chips support it - set the stbc support bit. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
2013-11-26iwlwifi: bump required firmware API version for 3160/7260Emmanuel Grumbach1-2/+2
A new firmware is coming out soon with new APIs. To make sure that this new firmware won't be loaded on old driver that don't support it, it's API version has been updated to 8. In order to be able to load it, bump the API version to 8. API version 7 is still supported and will be for another year or so. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2013-11-26iwlwifi: pcie: fix interrupt coalescing for 7260 / 3160Emmanuel Grumbach1-0/+7
We changed the timeout for the interrupt coealescing for calibration, but that wasn't effective since we changed that value back before loading the firmware. Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value. Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING. This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

2013-06-17iwlwifi: bump required firmware API version for 3160/7260Johannes Berg1-6/+6
As the firmware API has changed significantly and we don't have support code for the old APIs, bump the version to be able to release the version 7 API firmware. Unfortunately this means that the driver in 3.9 and 3.10 can't work, but that's still better than crashing the device/driver there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-03-06iwlwifi: make device configuration bus agnosticEmmanuel Grumbach1-0/+146
Newer devices can work on different buses. This means that their configuration can be shared between different buses. Hence the configuration structures should exported to all the buses and not only to PCIE. Change this. Note that this requires all the fields to be the same amongst the buses. If differences will appear, we can always define a part that is bus dependent. Today, this is not needed.
