* iwlwifi: support firmware reset handshakeJohannes Berg2020-12-101-0/+2
| | | | | | | | | | | | | | | There are some races in the hardware that can possibly lead to a bus lockup later during a restart when we manage to kill the firmware at a bad time (while it's accessing the bus). To work around this, add support for a new handshake between firmware and driver to ensure that the firmware is in a well- known state before we kill it.

* iwlwifi: Replace zero-length array with flexible-arrayGustavo A. R. Silva2020-06-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

* | iwlwifi: pcie: allocate smaller dev_cmd for TX headersJohannes Berg2019-12-231-6/+20
|/ | | | | | | | | | | | | | | | | | | | | As noted in the previous commit, due to the way we allocate the dev_cmd headers with 324 byte size, and 4/8 byte alignment, the part we use of them (bytes 20..40-68) could still cross a page and thus 2^32 boundary. Address this by using alignment to ensure that the allocation cannot cross a page boundary, on hardware that's affected. To make that not cause more memory consumption, reduce the size of the allocations to the necessary size - we go from 324 bytes in each allocation to 60/68 on gen2 depending on family, and ~120 or so on gen1 (so on gen1 it's a pure reduction in size, since we don't need alignment there). To avoid size and clearing issues, add a new structure that's just the header, and use kmem_cache_zalloc().

* iwlwifi: dbg_ini: remove apply point, switch to time point APIShahar S Matityahu2019-09-061-5/+0
| | | | | | | | | | Remove the "apply points" mechanism as preparation for the changed debug API where this is now a "time point" instead. Use a new API across the code at the trigger points ("time points"), but don't yet implement it since that requires some more preparation.

* iwlwifi: add support for suspend-resume flow for new device generationHaim Dreyfuss2019-09-061-5/+7
| | | | | | | | | | | | The new device generation has a slightly different suspend resume flow Currently, the way the driver instruct the device to move to D3 is by sending D3_CONFIG_CMD. Instead of using the host command the indication is by writing to the doorbell interrupt. The FW will respond with interrupt to indicate transition completion.

* iwlwifi: add a pointer to the trans_cfg directly in transLuca Coelho2019-09-061-0/+2
| | | | | | | | Add a pointer to the iwl_trans structure and point it to the trans part of the cfg. This is the first step in disassociating the trans configuration from the rest of the configuration. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: pcie: set iwl_trans->cfg later in the probe functionLuca Coelho2019-09-061-1/+0
| | | | | | | | | | | | | | | | | | | | | Instead of setting the cfg to iwl_trans already during allocation, set it only later when we have had the time to decide which cfg to use. This is part of the effort to be able to decide the cfg based on HW revision and RF ID after iwl_trans_alloc() has been called. For now, since we still have a bunch of code checking the HW revision and the RF ID, we set iwl_trans->cfg early, even before we decided the real cfg to use. We only use the trans configuration at this point, so this is fine for now. In the future, the trans configuration will be completely independent from the rest of the config structure, so we'll be able to avoid this. Additionally, we can't access the PRPH registers in iwl_trans_alloc() anymore, so move the HW REV C-step check for family 8000 code later to the probe function as well. This step is probably not necessary, but if that's the case it should be removed separately later on. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
* iwlwifi: dbg_ini: verify debug TLVs at allocation phaseShahar S Matityahu2019-09-061-5/+19
| | | | | | | | | | Reimplement debug TLV allocation flow. The driver will check the validity of the debug TLVs prior allocating space for them. Any malformed or unsupported TLV will be skipped. The TLV specific checks will be added in later patches. Signed-off-by: Shahar S Matityahu <shahar.s.matityahu@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

| | | | | | | | | | | | | | During D3 state, FW may send packets. As a result, "write" queue pointer will be incremented by FW.
