Static variables (and functions, unless they're inline) should not be declared in header files. Move the static array iro_arr[] from "qed_hsi.h" to the sole place where it's used, "qed_init_ops.c". This eliminates lots of warnings (42 of them actually) against W=1+: In file included from drivers/net/ethernet/qlogic/qed/qed.h:51:0, from drivers/net/ethernet/qlogic/qed/qed_ooo.c:40: drivers/net/ethernet/qlogic/qed/qed_hsi.h:4421:18: warning: 'iro_arr' defined but not used [-Wunused-const-variable=] static const u32 iro_arr[] = { ^~~~~~~ Signed-off-by: Alexander Lobakin <alobakin@marvell.com> Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.

2020-01-27qed: rt init valid initialization changedMichal Kalderon
The QM phase init tool can be invoked multiple times during the driver lifetime. Part of the init comes from the runtime array. The logic for setting the values did not init all values, basically assuming the runtime array was all zeroes. But if it was invoked multiple times, nobody was zeroing it after the first time. In this change we zero the runtime array right after using it.

2020-01-27qed: Use dmae to write to widebus registers in fw_funcsMichal Kalderon
There are several wide-bus registers written to by the fw_funcs that require using the dmae for atomicity. Therefore using the dmae channel functionality was added to the fw_funcs file, since the code is very similar to the previously used code, the structures used were moved to qed_hsi. Due to FW conventions, the names of the flags in the struct changed. Since this required slight modification in the places that set the flags the code was modified to use GET/SET FIELD macros.

This patch contains register initialization related changes. - Modifications to the runtime offsets - these are defines used by the driver or firmware functions to set values that are used by the initialization functions to set device register values. - Global window values changes to provide different device register ranges. - Additional device registers addresses were added to the register file, used in later stages.

2019-05-26qed: Modify api for performing a dmae to another PFMichal Kalderon
This patch modifies the dmae API to enable performing a dmae operation to another PF. This enables sharing between the llh entries between PFs and thus increasing the amount of filters per PF under certain configurations. The llh entries require using the dmae since the memory is widebus, which requires atomicity in access.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2017-03-13qed*: Utilize Firmware 8.15.3.0Mintz, Yuval
This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].

2016-08-19qed: utilize FW 8.10.10.0Yuval Mintz
This new firmware for the qed* adpaters fixes several issues: - Better blocking of malicious VFs. - After FLR, Tx-switching [internal routing] of packets might be incorrect. - Deletion of unicast MAC filters would sometime have side-effect of corrupting the MAC filters configred for a device. It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities. This would also bump the qed* driver versions to 8.10.9.20. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-05-12qed: Introduce VFsYuval Mintz
This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them. This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

2015-10-27qed: Add module with basic common supportYuval Mintz
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
