ddcdf364b7 gpu: nvgpu: use public APIs of engine_status_info unit
nvgpu driver presently uses h/w functions to read and process
the engine_status registers. H/w headers shouldn't be directly invoked
by common code and should be called via HAL layer. This patch replaces
the h/w headers with the APIs in the engine_status_info unit.

cd4b2f642c gpu: nvgpu: add HAL for reading ccsr_channel
Refactor read accesses to the ccsr_channel register for channel state to
be done via a channel HAL op for all chips. A new op called read_state
is added for this; information needed by other units is collected in a
new struct nvgpu_channel_hw_state.

Extract out the HAL ops' implementation that now belongs to the channel
unit. This unit is responsible for channel register accesses and the

Rename channel_gm20b_bind to gm20b_fifo_channel_bind to match with the
rest of the naming. Same with channel_gv11b_unbind.

c330d8fd98 gpu: nvgpu: add channel HAL section for ccsr_*
Split out ops that belong to channel unit to a new section called
channel. Channel is a broad concept; this includes just the code that
accesses channel registers (ccsr_*). This is effectively just renaming;
the implementation still stays put.

The word "channel" is also dropped from certain HAL entries to avoid
redundancy (e.g., channel.disable_channel -> channel.disable).
fifo.get_num_fifos gets an entirely new name: channel.count.

49506f257e gpu: nvgpu: split update_runlist HAL API in two
A comment for gk20a_fifo_update_runlist() says:

 /* add/remove a channel from runlist
    special cases below: runlist->active_channels will NOT be changed.
    (ch == NULL && !add) means remove all active channels from runlist.
    (ch == NULL &&  add) means restore all active channels on runlist. */

Those special cases call for a new function, so add that. Delete the
update_runlist HAL op and add update_for_channel (like update_runlist
without the special cases) and reload (no channel to add or remove, just
the special cases).

While at it, rename gk20a_fifo_update_runlist_ids to
nvgpu_runlist_reload_ids. It's common across chips and does what the
reload HAL does but for a list of several IDs.

MISRA Rule 10.1 states that operands shall not be of an inappopriate
essential type.  For example, shift and bitwise operations should only
be performed on operands of essentially unsigned type.

This patch modifies gr exception handling to no longer use bitwise OR
when generating return status values.

Instead, the first non-zero status value is saved off and returned.

This has the added benefit of not potentially ORing together errno
values and generating an undefined status code.

136a31fcd4 gpu: nvgpu: container_of() changes to clk code
While not necessary for MISRA compliance purposes, this change
modifies the linux platform clk code use of container_of() to follow
similar changes applied to address the following rule violations:

 * Rule 11.3 : A cast shall not be performed between a pointer to
               object type and a pointer to a different object type.
 * Rule 11.8 : A cast shall not remove any const or volatile
               qualification from the type pointed to be a pointer.
 * Rule 20.7 : Expressions resulting from the expansion of macro
               parameters shall be enclosed in parentheses.

This patch replaces the to_clk_gk20a() macro with a new (static)
clk_gk20a_from_hw() function that eliminates the Rule 11.8 and
Rule 20.7 violations and exchanges the Rule 11.3 violation with
an advisory Rule 11.4 violation.

It should be noted that the replacement function still contains
potentially dangerous (and non-MISRA compliant code) and that it is
expected that deviation requests will be filed for the new advisory
rule violations where appropriate.

Regops does not depend on debug session logically
We right now include debugger.h in regops_gk20a.c to extract
channel pointer from debug session and to check if session is for
profiling or not

flag directly as parameters, and remove dbg_session_gk20a from
parameter list

Remove ((!dbg_s->is_profiler) && (ch != NULL)) checks from
check_whitelists(). Caller of exec_regops_gk20a() already ensures
that we have context bound for debug session
Use only is_profiler boolean flag in this case which should be
sufficient

Remove (ch == NULL) check in check_whitelists() if regops is of
type gr_ctx. Instead move this check to earlier function call
in validate_reg_ops(). If we have non-zero context operation on
a profiler session, return error from validate_reg_ops()

f910525e14 gpu: nvgpu: cleanup idle_wait and wait_empty APIs
All cases where the wait_empty HAL API and the wait_idle, wait_fe_idle
APIs were being called used the same parameters, so move those
parameters inside the APIs.

4ba92354c0 gpu: nvgpu: container_of() changes to tsg/fence code
The container_of() macro used in nvgpu produces the following
set of MISRA required rule violations:

* Rule 11.3 : A cast shall not be performed between a pointer to
              object type and a pointer to a different object type.

* Rule 11.8 : A cast shall not remove any const or volatile
              qualification from the type pointed to be a pointer.

* Rule 20.7 : Expressions resulting from the expansion of macro
              parameters shall be enclosed in parentheses

Using the same modified implementation of container_of() as that
used in the nvgpu_list_node/nvgpu_rbtree_node routines eliminates
the Rule 11.8 and Rule 20.7 violations and exchanges the Rule 11.3
violation with an advisory Rule 11.4 violation.

This patch uses that same equivalent implementation in two new
(static) functions that are used to replace references to
container_of() references in tsg and fence code:

 * tsg_gk20a_from_ref
 * gk20a_fence_from_ref

It should be noted that replacement functions still contain
potentially dangerous (and non-MISRA compliant code) and that it is
expected that deviation requests will be filed for the new advisory
rule violations accordingly.
