2020-05-08iwlwifi: use longer queues for 256-BAJohannes Berg1-1/+1
When we have 256 block-ack support, we may need to be very fast to provide a lot of frames to the hardware to transmit, but that cannot be guaranteed. Use a longer queue size to have more time, and the next possible queue size is 1024 since it must be a power of two.

2020-05-08iwlwifi: pcie: allocate much smaller byte-count tableJohannes Berg1-4/+3
The hardware needs a byte-count table with the size of each frame on the queue to build A-MPDUs, but: * newer generation no longer have the duplicated space at the end, they can deal with the wrap properly - and we don't even fill the dup anyway * we have a maximum queue size of 512 right now and don't use the theoretical hardware maximum of 65536. Together, this reduces the byte count table DMA allocation from 64KiB (65536*2 + 64*2 rounded up) to 1 KiB (though that might be rounded up to a full 4 KiB page by the allocator, not sure it can share the allocations.)

2019-12-23iwlwifi: allocate more receive buffers for HE devicesJohannes Berg1-4/+1
For HE-capable devices, we need to allocate more receive buffers as there could be 256 frames aggregated into a single A-MPDU, and then they might contain A-MSDUs as well. Until 22000 family, the devices are able to put multiple frames into a single RB and the default RB size is 4k, but starting from AX210 family this is no longer true. On the other hand, those newer devices only use 2k receive buffers (by default). Modify the code and configuration to allocate an appropriate number of RBs depending on the device capabilities: * 4096 for AX210 HE devices, which use 2k buffers by default, * 2048 for 22000 family devices which use 4k buffers by default, * 512 for existing 9000 family devices, which doesn't really change anything since that's the default before this patch, * 512 also for AX210/22000 family devices that don't do HE. Theoretically, for devices lower than AX210, we wouldn't have to allocate that many RBs if the RB size was manually increased, but to support that the code got more complex, and it didn't really seem necessary as that's a use case for monitor mode only, where hopefully the wasted memory isn't really much of a concern. Note that AX210 devices actually support bigger than 12-bit VID, which is required here as we want to allocate 4096 buffers plus some for quick recycling, so adjust the code for that as well.

This is dead code, nothing uses the IWL_DEVICE_22560 macro and thus nothing every uses IWL_DEVICE_FAMILY_22560. Remove it all.

2019-09-06iwlwifi: add a pointer to the trans_cfg directly in transLuca Coelho1-1/+1
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>
2019-09-06iwlwifi: separate elements from cfg that are needed by trans_allocLuca Coelho1-3/+3
In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

2017-04-11iwlwifi: pcie: add context information supportSara Sharon1-0/+4
Context information structure is going to be used in a000 devices for firmware self init. The self init includes firmware self loading from DRAM by ROM. This means the TFH relevant firmware loading can be cleaned up. The firmware loading includes the paging memory as well, so op mode can stop initializing the paging and sending the DRAM_BLOCK_CMD. Firmware is doing RFH, TFH and SCD configuration, while driver only fills the required configurations and addresses in the context information structure. The only remaining access to RFH is the write pointer, which is updated upon alive interrupt after FW configured the RFH.

2016-05-10iwlwifi: pcie: use shadow registers for updating write pointerSara Sharon1-0/+3

2016-03-09iwlwifi: pcie: fine tune number of rxbsSara Sharon1-3/+6
We kick the allocator when we have 2 RBDs that don't have attached RBs, and the allocator allocates 8 RBs meaning that it needs another 6 RBDs to attach the RBs to. The design is that allocator should always have enough RBDs to fulfill requests, so we give in advance 6 RBDs to the allocator so that when it is kicked, it gets additional 2 RBDs and has enough RBDs. These RBDs were taken from the Rx queue itself, meaning that each Rx queue didn't have the maximal number of RBDs, but MAX - 6. Change initial number of RBDs in the system to include both queue size and allocator reserves. Note the multi-queue is always 511 instead of 512 to avoid a full queue since we cannot detect this state easily enough in the 9000 arch.

2016-01-31iwlwifi: pcie: add 9000 series multi queue rx DMA supportSara Sharon1-0/+77
The 9000 series introduces several changes in the device DMA operation. As the device now supports multi-queue rx, several DMA channels should be configured. The flows of providing the device with the allocated RBDs now changes as well - the device maintains a separate table of used and free table. The hardware may use the free table to feed RBDs to any queue. This requires maintaing a shared table to map returned RBDs to the original RXB - for that purpose the VID is introduced - an internal identifier of the RB placed in the lower 12 bits and returned by HW in the used data. Another change is the support of 64 bit DMA address. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
