Detailed Description

This file contains all HAL runtime workaround code. Based on the asic type, asic revision, and range of fw revisions, a particular workaround may be enabled.

A workaround may consist of overriding a particular HAL/SLI4 value that was initialized during ocs_hal_setup() (for example the MAX_QUEUE overrides for mis-reported queue sizes). Or if required, elements of the ocs_hal_workaround_t structure may be set to control specific runtime behavior.

It is intended that the controls in ocs_hal_workaround_t be defined functionally. So we would have the driver look like: "if (hal->workaround.enable_xxx) then ...", rather than what we might previously see as "if this is a BE3, then do xxx"

Function Details

static int32_t ocs_hal_workaround_match ( ocs_hal_t *  hal, hal_workaround_t *  w  )

static

Function prototypes.

Test for a workaround match.

Looks at the asic type, asic revision, and fw revision, and returns TRUE if match.

Parameters

hal	Pointer to the HAL structure
w	Pointer to a workaround structure entry

Returns

Return TRUE for a match

Definition at line 217 of file ocs_hal_workaround.c.

void ocs_hal_workaround_setup

(

struct ocs_hal_s *

hal

)

Setup HAL runtime workarounds.

The function is called at the end of ocs_hal_setup() to setup any runtime workarounds based on the HAL/SLI setup.

Parameters

hal	Pointer to HAL structure

Returns

none

Definition at line 237 of file ocs_hal_workaround.c.

static uint64_t parse_fw_version ( const char *  fwrev_string )

static

Parse the firmware version (name)

Parse a string of the form a.b.c.d, returning a uint64_t packed as defined by the HAL_FWREV() macro

Parameters

fwrev_string

pointer to the firmware string

Returns

packed firmware revision value
