[PATCH] drm/i915/tgl: MOCS table fixes

[Matt Roper]

The bspec was just updated with a couple corrections to the TGL MOCS
table.  Entries 16 and 17 are marked as reserved (overriding the value
we inherit from GEN11_MOCS_ENTRIES) and entry 61 shouldn't have the
LE_SCF bit applied.

Note that since we're intentionally/explicitly overriding table entries
from GEN11_MOCS_ENTRIES we should suppress the 'override-init' compiler
warnings for this file.

The bspec was just updated with a couple corrections to the TGL MOCS
table.  Entries 16 and 17 are marked as reserved (overriding the value
we inherit from GEN11_MOCS_ENTRIES) and entry 61 shouldn't have the
LE_SCF bit applied.

Note that since we're intentionally/explicitly overriding table entries
from GEN11_MOCS_ENTRIES we should suppress the 'override-init' compiler
warnings for this file.

I'm pretty sure at some point I had a pragma push/pop to ignore
this warning just around the tables and nothing else. Probably it was
dropped in a patch revision, because git log doesn't show it.

It looks like we even define special macros __diag_push(), __diag_pop(),
__diag_ignore() for that, but it doesn't see much use in the kernel, not
sure why.

MOCS_ENTRY implicitly define the entry to used. What I think we need is
a way to override the used field, so it's more inline with what the
bspec is telling us to do...

probably something like

#define MOCS_ENTRY_SET_UNUSED(__idx) \
	[__idx] = { \
		.used = 0, \
	}

Difference is that in tests that read back the value and check if they
make sense, they won't test values that are marked as not used. IMO what
we should be doing for these fields.

Makes sense.  And we should probably switch the existing reserved
entries (0 and 1) over to that as well?

[PATCH v2] drm/i915/tgl: MOCS table fixes

[Matt Roper]

The bspec was just updated with a couple corrections to the TGL MOCS
table.  Entries 16 and 17 are marked as reserved (overriding the value
we inherit from GEN11_MOCS_ENTRIES) and entry 61 shouldn't have the
LE_SCF bit applied.

Note that since we're intentionally/explicitly overriding table entries
from GEN11_MOCS_ENTRIES we should suppress the 'override-init' compiler
warnings for the TGL table.

v2:
 - Add a MOCS_ENTRY_UNUSED() and use it to declare the
   explicitly-reserved MOCS entries. (Lucas)
 - Move the warning suppression from the Makefile to a #pragma that only
   affects the TGL table. (Lucas)
