module: Convert symbol namespace to string literal

2024-12-02T19:34:44+00:00

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

accel/ivpu: Move secondary preemption buffer allocation to DMA range

2024-10-30T09:23:57+00:00

Secondary preemption buffer is accessible by NPU's DMA and can be
allocated with addresses above 4 GB. Move secondary preemption buffer
allocation from SHAVE range which is much smaller (2GB) to DMA range.
This allows to allocate more command queues with corresponding
preemption buffers without running out of address range.

accel/ivpu: Increase DMA address range

2024-10-30T09:23:57+00:00

Increase DMA address range to:
 * 128 GB on 37xx (due to MMU limitations)
 * 256 GB on other generations
Merge User and DMA ranges on 40xx and above as it is possible
to access whole 256 GBs from both FW and DMA.

Increase User range on 37xx from 255MB to 511MB
to allow loading very large models.

Do not set global_alias_pio_base/size on other generations than 37xx
as it's only used on 37xx anyway.

 - Adds -DDEBUG that enables printk regardless of the kernel config
 - Enables unsafe module params (that are now disabled by default)

accel/ivpu: Don't allocate preemption buffers when MIP is disabled

2024-10-30T09:22:09+00:00

Do not allocate preemption buffers when Mid Inference Preemption (MIP)
is disabled through test mode.

Rename IVPU_TEST_MODE_PREEMPTION_DISABLE to IVPU_TEST_MODE_MIP_DISABLE
to better describe that this test mode only disables MIP - job level
preemption will still occur.

accel/ivpu: Make command queue ID allocated on XArray

2024-10-30T09:22:08+00:00

Use XArray for dynamic command queue ID allocations instead of fixed
ones. This is required by upcoming changes to UAPI that will allow to
manage command queues by user space instead of having predefined number
of queues in a context.

accel/ivpu: Use xa_alloc_cyclic() instead of custom function

2024-10-30T09:22:07+00:00

Remove custom ivpu_id_alloc() wrapper used for ID allocations
and replace it with standard xa_alloc_cyclic() API.

The idea behind ivpu_id_alloc() was to have monotonic IDs, so the driver
is easier to debug because same IDs are not reused all over. The same
can be achieved just by using appropriate Linux API.

Don't leave a context descriptor in case CFGI_ALL flush fails.
Mark it as invalid (by clearing valid bit) so nothing is left in
