* drm/i915: stop conflating HAS_DISPLAY() and disabled displayJani Nikula2019-09-161-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Stop setting ->pipe_mask to zero when display is disabled, allowing us to have different code paths for not actually having display hardware, and having display hardware disabled. This lets us develop those two avenues independently. There are no functional changes for when there is no display. However, all uses of for_each_pipe() and for_each_pipe_masked() will start running for the disabled display case. Put one of the more significant ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases should not be hit with disabled display, or they seem benign. Fingers crossed. All in all, this might not be the ideal solution. In fact we may have had something along the lines of this in the past, but we ended up conflating the two cases. Possibly even by recommendation by yours truly; I did not dare dig up that part of the history. But the perfect is the enemy of the good, this is a straightforward change, and lets us get actual work done in both fronts without interfering with each other.

* drm/i915: rework reading pipe disable fusesLucas De Marchi2019-06-281-23/+13
| | | | | | | | | | | | | | | | | | | | This prepares to have possibly more than 3 pipes. I didn't want to continue the previous approach since the check for "are the disabled pipes the last ones" poses a combinatory explosion. We need that check because in several places of the code we have that assumption. If that ever becomes false in a new HW, other parts of the code would have to change. Now we start by considering we have info->num_pipes enabled and disable each pipe that is marked as disabled. Then it's a simple matter of checking if we have at least one pipe and that all the enabled ones are the first pipes, i.e. there are no holes in the bitmask.

The commit exposes an issue in commit 1e40d4aea57b ("drm/i915/cnl: Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will also need to be addressed. There's a proposed fix [1], but considering the seeming uncertainty with the fix as well as the size of the regressing commit (in this context, the one that actually brings down ICL), this warrants a revert to get ICL working, and gives us time to get all of this right without rushing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Concept of a sub-platform already exist in our code (like ULX and ULT platform variants and similar),implemented via the macros which check a list of device ids to determine a match. With this patch we consolidate device ids checking into a single function called during early driver load. A few low bits in the platform mask are reserved for sub-platform identification and defined as a per-platform namespace. At the same time it future proofs the platform_mask handling by preparing the code for easy extending, and tidies the very verbose WARN strings generated when IS_PLATFORM macros are embedded into a WARN type statements. v2: Fixed IS_SUBPLATFORM. Updated commit msg. v3: Chris was right, there is an ordering problem. v4: * Catch-up with new sub-platforms. * Rebase for RUNTIME_INFO. * Drop subplatform mask union tricks and convert platform_mask to an array for extensibility. v5: * Fix subplatform check. * Protect against forgetting to expand subplatform bits. * Remove platform enum tallying. * Add subplatform to error state. (Chris) * Drop macros and just use static inlines. * Remove redundant IRONLAKE_M. (Ville) v6: * Split out Ironlake change. * Optimize subplatform check. * Use __always_inline. (Lucas) * Add platform_mask comment. (Paulo) * Pass stored runtime info in error capture. (Chris) v7: * Rebased for new AML ULX device id. * Bump platform mask array size for EHL. * Stop mentioning device ids in intel_device_subplatform_init by using the trick of splitting macros i915_pciids.h. (Jani) * AML seems to be either a subplatform of KBL or CFL so express it like that. v8: * Use one device id table per subplatform.
