Channel table can be bigger than one page, so allocate it with
vmalloc.
Also add a free for tsg table, which did not exist before, and
remove per-channel remove_channel callback which was never used.

We currently free sync when we find job list empty
If aggressive_sync is set to true, we try to free
sync during channel unbind() call
But we rarely free sync from channel_unbind() call
since freeing it when job list is empty is
aggressive enough
Hence remove sync free code from channel_unbind()
Implement refcounting for sync:
- get a refcount while submitting a job (and
allocate sync if it is not allocated already)
- put a refcount while freeing the job
- if refcount==0 and if aggressive_sync_destroy is
set, free the sync
- if aggressive_sync_destroy is not set, we will
free the sync during channel close time

We currently bind only one channel to a debug session
But some use cases might need multiple channels bound
to same debug session
Add this support by adding a list of channels to debug session.
List structure is implemented as struct dbg_session_channel_data
List node dbg_s_list_node is currently defined in struct
dbg_session_gk20a. But this is inefficient when we need to
add debug session to multiple channels
Hence add new reference structure dbg_session_data to
store dbg_session pointer and list entry
For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create
two reference structure dbg_session_channel_data for channel
and dbg_session_data for debug session and bind them together
Define API nvgpu_dbg_gpu_get_session_channel() which will
get first channel in the list of debug session
Use this API wherever we refer to channel bound to debug
session
Remove dbg_sessions define in struct gk20a since it is
not being used anywhere
Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support
unbinding of channel from debug sesssion

Make necessary changes to support nvgpu on kernel-3.10
This includes below changes
- PROBE_PREFER_ASYNCHRONOUS is defined only for K3.10
- Fence handling and struct sync_fence is different between
K3.10 and K3.18
- variable status in struct sync_fence is atomic on K3.18
whereas it is int on K3.10
- if SOC == T132, set soc_name = "tegra13x"
- ioremap_cache() is not defined on K3.10 ARM versions,
hence use ioremap_cached()

With NVGPU_IOCTL_CHANNEL_EVENTS_CTRL, nvgpu can
raise events to User space. But user space
cannot distinguish between various types of events.
To overcome this, we need finer-grained API to
deliver various events to user space.
Remove old API NVGPU_IOCTL_CHANNEL_EVENTS_CTRL,
and all the support for this API (we can remove
this since User space has not started using this
API at all)
Add new API NVGPU_IOCTL_CHANNEL_EVENT_ID_CTRL
which will accept an event_id (like BPT.INT or
BPT.PAUSE), a command to enable the event,
and return a file descriptor on which
we can raise the event (if cmd=enable)
Event is disabled when file descriptor is closed
Add file operations "gk20a_event_id_ops"
to support polling on event fd
Also add API gk20a_channel_get_event_data_from_id()
to get event_data of event from its id

bug 1648908
This commit adds support for FECS ctxsw tracing. Code is compiled
conditionnaly under CONFIG_GK20_CTXSW_TRACE.
This feature requires an updated FECS ucode that writes one record to a ring
buffer on each context switch. On RM/Kernel side, the GPU driver reads records
from the master ring buffer and generates trace entries into a user-facing
VM ring buffer. For each record in the master ring buffer, RM/Kernel has
to retrieve the vmid+pid of the user process that submitted related work.
Features currently implemented:
- master ring buffer allocation
- debugfs to dump master ring buffer
- FECS record per context switch (with both current and new contexts)
- dedicated device for ctxsw tracing (access to VM ring buffer)
- SOF generation (and access to PTIMER)
- VM ring buffer allocation, and reconfiguration
- enable/disable tracing at user level
- event-based trace filtering
- context_ptr to vmid+pid mapping
- read system call for ctxsw dev
- mmap system call for ctxsw dev (direct access to VM ring buffer)
- poll system call for ctxsw dev
- save/restore register on ELPG/CG6
- separate user ring from FECS ring handling
Features requiring ucode changes:
- enable/disable tracing at FECS level
- actual busy time on engine (bug 1642354)
- master ring buffer threshold interrupt (P1)
- API for GPU to CPU timestamp conversion (P1)
- vmid/pid/uid based filtering (P1)

Previously, only "high" priority bare channels were interleaved
between all other bare channels and TSGs. This patch decouples
priority from interleaving and introduces 3 levels for interleaving
a bare channel or TSG: high, medium, and low. The levels define
the number of times a channel or TSG will appear on a runlist (see
nvgpu.h for details).
By default, all bare channels and TSGs are set to interleave level
low. Userspace can then request the interleave level to be increased
via the CHANNEL_SET_RUNLIST_INTERLEAVE ioctl (TSG-specific ioctl will
be added later).
As timeslice settings will soon be coming from userspace, the default
timeslice for "high" priority channels has been restored.

Restore comptags to be bitmap-allocated, like they were before we had
the buddy allocator.
The new buddy allocator introduced by
e99aa2485f8992eabe3556f3ebcb57bdc8ad91ff (originally
6ab2e0c49cb79ca68d2f83f1d4610783d2eaa79b) is fine for the big VAs, but
unsuitable for the small compbit store.
This commit reverts partially the combination of the above commit and
also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed
a bug which is not present when using a bitmap. With a bitmap allocator,
pruning the extra allocation necessary for user-mapped mode is possible,
so that is also restored.
The original generic bitmap allocator is not restored; instead, a
comptag-only allocator is introduced.

Current sequence in gk20a_disable_channel() is
- disable channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
- preempt channel
But this leads to scenarios where syncpoint has
min > max value
Hence to fix this, make sequence in gk20a_disable_channel()
- disable channel in gk20a_channel_abort()
- preempt channel in gk20a_channel_abort()
- adjust pending fence in gk20a_channel_abort()
If gk20a_channel_abort() is called from other API where
preemption is not needed, then use channel_preempt
flag and do not preempt channel in those cases

Implement NVGPU_GPU_IOCTL_ALLOC_AS_FLAGS_USERSPACE_MANAGED, which
enables creating userspace-managed GPU address spaces.
When an address space is marked as userspace-managed, the following
changes are in effect:
- Only fixed-address mappings are allowed.
- VA space allocation for fixed-address mappings is not required,
except to mark space as sparse.
- Maps and unmaps are always immediate. In particular, the mapping
ref increments at kickoffs and decrements at job completion are
skipped.

Separate the kernel and userspace regions in the GPU virtual address
space. Do this by reserving the last part of the GPU VA aperture for
the kernel, and extend GPU VA aperture accordingly for regular address
spaces. This prevents the kernel polluting the userspace-visible GPU
VA regions, and thus, makes the success of fixed-address mapping more
predictable.

Add batch support for mapping and unmapping. Batching essentially
helps transform some per-map/unmap overhead to per-batch overhead,
namely gk20a_busy()/gk20a_idle() calls, GPU L2 flushes, and GPU TLB
invalidates. Batching with size 64 has been measured to yield >20x
speed-up in low-level fixed-address mapping microbenchmarks.
