* iwlwifi: mvm: revisit the NVM handling codeEran Harary2014-05-13
| | | | | | | | | | | | | | | | | | | | | Fix a bug in nvm_read_section function if size of the section is a multiple of 2K: - if the size of the section is *not* multiple of 2K, then we will have: read(2K) - return 2K ... read(2K) - return 2K read(2K) - return the rest (in bytes) and exit the while loop. - else, if the size of the section is a multiple of 2K, then we have: read(2K) - return 2K read(2K) - return 2K read(2K) - return 2K read(2K) - return 0 and exit the while with an error. We should not return an error in the latter case, because it might well be that the section was completely read. Also, we try now to read all the sections as this is needed for new devices.

* iwlwifi: don't disable SCD chain extension on newer devicesEmmanuel Grumbach2014-04-13
| | | | | | | | | | | 7000 device series have a fix for this hardware feature. Stop disabling it, and get an improvement in Tx throughput. This feature allows the scheduler to fetch more frames on the fly while an A-MPDU is being built - which means that we can get larger A-MPDU. This, of course, give an improvement in the Tx throughput. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
* iwlwifi: pcie: don't leave the new NICs awake for commandsEmmanuel Grumbach2014-04-06
| | | | | | | | | | | | | | | | | | 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.

* iwlwifi: pcie: enable LP XTAL to reduce power consumptionAlexander Bondar2014-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: add D0i3 references boiler plateEliad Peller2014-02-03
| | | | | | | | | | | | | | | | | | | | | D0i3 is bus power saving feature. It involves the firmware - the driver needs to send a list of commands to the firmware before entering this state. Wake up from d0i3 also requires a few commands to the firmware. The trigger to enter D0i3 is an idle timeout that will be implemented later and will most probably rely on RUNTIME_PM infrastructure. In order to prevent entrance to D0i3 in critical flows, we implement here a reference infrastructure. When a ref is taken, we can't enter D0i3. PCIe does't support D0i3.

* iwlwifi: mvm: handle platform PCIe power limitationIdo Yariv2014-02-03
| | | | | | | | | | | | | | | | The tx backoff settings used by the thermal throttling mechanism can also be used for enforcing a limit on the power consumption of the module. Handle the platform PCIe power limitation by translating the limit (measured in mw) to its respective tx backoff value. The translation is module specific. The resulting tx backoff value is sent to the ucode, and also serves as the minimal backoff value that can be set by the thermal throttling mechanism.

* iwlwifi: pcie: fix interrupt coalescing for 7260 / 3160Emmanuel Grumbach2013-11-25
| | | | | | | | | | | | | | | | | | | | | | 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.

* iwlwifi: refactor EEPROM reading/parsingJohannes Berg2012-06-06
| | | | | | | | | | | | | | | | | | | The EEPROM reading/parsing code is all mixed in the driver today, and the EEPROM is parsed only when we access data from it. This is problematic because the NVM needs to be parsed and that is independent of reading it. Also, the NVM format for new devices will be different and probably require a new parser. Therefore refactor the reading and parsing and create two independent components. Reading the EEPROM requires direct hardware accesses and therefore access to the transport, but parsing is independent and can be done on an NVM blob.
