bnxt: revert hastily merged uAPI aberrations

2022-03-10T03:55:00Z

This reverts: commit 02acd399533e ("bnxt_en: parse result field when NVRAM package install fails") commit 22f5dba5065d ("bnxt_en: add an nvm test for hw diagnose") commit bafed3f231f7 ("bnxt_en: implement hw health reporter") These patches are still under discussion / I don't think they are right, and since the authors don't reply promptly let me lessen my load of "things I need to resolve before next release" and revert them.

bnxt_en: implement hw health reporter

2022-03-05T11:16:56Z

This reporter will report NVM errors which are non-fatal. When we receive these NVM error events, we'll report it through this new hw health reporter. Reviewed-by: Edwin Peer Signed-off-by: Kalesh AP Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: Do not destroy health reporters during reset

2022-03-05T11:16:56Z

Health reporter state should be maintained over resets. Previously reporters were destroyed if the device capabilities changed, but since none of the reporters depend on capabilities anymore, this logic should be removed.

bnxt_en: remove fw_reset devlink health reporter

2021-10-29T11:13:05Z

Firmware resets initiated by the user are not errors and should not be reported via devlink. Once only unsolicited resets remain, it is no longer sensible to maintain a separate fw_reset reporter. Signed-off-by: Edwin Peer Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: add enable_remote_dev_reset devlink parameter

2021-10-29T11:13:05Z

The reported parameter value should not take into account the state of remote drivers. Firmware will reject remote resets as appropriate, thus it is not strictly necessary to check HOT_RESET_ALLOWED before attempting to initiate a reset. But we add the check so that we can provide more intuitive messages when reset is not permitted. This firmware setting needs to be restored from all functions after a firmware reset.

bnxt_en: implement devlink dev reload fw_activate

2021-10-29T11:13:05Z

Similar to reload driver_reinit, the RTNL lock is held across reload down and up to prevent interleaving state changes. But we need to subsequently release the RTNL lock while waiting for firmware reset to complete. Also keep a statistic on fw_activate resets initiated remotely from other functions.

bnxt_en: Check devlink allocation and registration status

2021-09-24T13:12:56Z

devlink is a software interface that doesn't depend on any hardware capabilities. The failure in SW means memory issues, wrong parameters, programmer error e.t.c. Like any other such interface in the kernel, the returned status of devlink APIs should be checked and propagated further and not ignored.

bnxt_en: fix read of stored FW_PSID version on P5 devices

2021-09-05T19:43:03Z

P5 devices store NVM arrays using a different internal representation. This implementation detail permeates into the HWRM API, requiring the caller to explicitly index the array elements in HWRM_NVM_GET_VARIABLE on these devices. Conversely, older devices do not support the indexed mode of operation and require reading the raw NVM content. Fixes: db28b6c77f40 ("bnxt_en: Fix devlink info's stored fw.psid version format.")

bnxt_en: Refactor bnxt_dl_info_get().

2020-10-12T21:27:03Z

Add a new function bnxt_dl_info_put() to simplify the code, as there are more stored firmware version fields to be added in the next patch. Also, rename fw_ver variable name to ncsi_ver for better naming while copying to devlink info_get cb. v2: Ensure active_pkg_name string is NULL terminated when copied to devlink. Return directly from the last call to bnxt_dl_info_put().
