* iwlwifi: pcie: enable LP XTAL to reduce power consumptionAlexander Bondar2014-03-097-3/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* iwlwifi: mvm: disable power on P2P client when BSS is addedAvri Altman2014-03-091-5/+12
| | | | | | | | | | | | | | | | | | | | | When power update is initiated on BSS STA while P2P client exists, the power command will be sent only on BSS STA vif ignoring P2P client. Since the firmware has symmetric constraints on the power save enablement we can simplify the code a bit. The current firmware doesn't know how to enable power management on P2P client. Even BSS power management must be disabled when a P2P client is added. Future firmware will support power save on BSS and P2P client as long as they are on different channels. This was buggy since we didn't disable power management on P2P client interface if BSS added on the same channel.

In order to detect such behavior, mwifiex must note the starting sequence number given during the ADDBA request. If the first received sequence number after the ADDBA falls outside the receive window for this TID but after the the ADDBA starting sequence number, we can assume that this AP has reset its sequence number during the ADDBA. In this case we must adjust the input window backward to incorporate this received sequence number instead of ignoring it. Otherwise, we could fail to successfully retrieve an arbitrarily large number of downstream frames at the beginning of the block-ACK session.
