Each completion queue has a structure. This is mainly for passing to irq handler so we know which queue the irq occured on. Signed-off-by:

Add functionality to init slot indexing. Slot indexing is for the host to track which slots (or tags) are free and which are used. Signed-off-by:

Allocate DMA and non-DMA memories for the controller. Also create DMA pools. These include: - Delivery queues - Completion queues - Command status buffer - Command table - ITCT (For device context) - Host slot info - IO status - Breakpoint - host slot indexing - SG data - FIS - interrupts names Signed-off-by:

This patch adds the initial bare main driver for the HiSilicon SAS HBA. This only introduces the changes to build and load the main driver module. The complete driver consists of the core main module and also a module platform driver for driving the hw. The HBA is a platform device. Signed-off-by:

Call _init_tables before chip-specific initialization. This avoids code duplication and fixes a bug(?) in 880 init where the values read from flash into atpdev->sp are then overwritten by calling init_tables. Signed-off-by:

scam_on is used only during probe, no need to keep it later. Signed-off-by:

Ondrej Zary authored
Allocate IRQ later during probe to avoid code duplication and also remove the need for weird locking in _probe. (It was probably there to prevent race with the IRQ handler?) Signed-off-by:

chip_ver is used for wide chip detection only. Remove it and use a local variable instead (for 870; 880 and 885 are always wide). Signed-off-by:

The ioport region is 0x20 bytes long so accessing 0x3a register using writeb_io is incorrect. Use writeb_base instead. There's no change in behavior as 870 chips have ioport = baseport. Signed-off-by:
