2023-01-05drm/i915: Expand force_probe to block probe of devices as well.Rodrigo Vivi1-5/+28
There are new cases where we want to block i915 probe, such as when experimenting or developing the new Xe driver. But also, with the new hybrid cards, users or developers might want to use i915 only on integrated and fully block the probe of the i915 for the discrete. Or vice versa. There are even older development and validation reasons, like when you use some distro where the modprobe.blacklist is not present. But in any case, let's introduce a more granular control, but without introducing yet another parameter, but using the existent force_probe one. Just by adding a ! in the begin of the id in the force_probe, like in this case where we would block the probe for Alder Lake: $ insmod i915.ko force_probe='!46a6' v2: Take care of '*' and '!*' cases as pointed out by Gustavo and Jani.

The attribute __maybe_unused should remain only until the respective info is not in the pciidlist. The info can't be added together with its definition because that would cause the driver to automatically probe for the device, while it's still not ready for that.

2022-11-22drm/i915: Add 10bit gamma mode for gen2/3Ville Syrjälä1-5/+5
Some gen2/gen3 parts have a 10bit gamma mode, on some pipes. Expose it. The format is different to the later i965+ style in that we store a 10bit value and a 6 bit floating point slope for each entry. Ie. the hardware extrapolates the intermediate steps from the current LUT entry, instead of interpolating between the current and next LUT entries. This also means we don't store the last LUT entry in any register as it is defined by the previous LUT entry's value+slope. The slope has limited precision though (2 bit exponent + 4 bit mantissa), so we'd have to allow for more error in the state checker for the last entry and we have to make sure userspace doesn't pass in something where the slope is simply to steep. In theory we should perhaps check the slope for every interval, but we don't do that for any other interpolated gamma mode and I suspect they may also have some internal limit on the slope. I haven't confirmed that theory though. Anyways, for ease of implementation we shall just ignore the last entry in the state checker. If all the other entries match anyway then that seems like a good indication that the hardware was programmed as expected. v2: Redo the state checker logic a bit Rebase due to other changes v3: Fix C8 readout v4: Use REG_FIELD_PREP() Acked-by: Uma Shankar <uma.shankar@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221114153732.11773-20-ville.syrjala@linux.intel.com

2022-10-17drm/i915/xelpg: Add multicast steeringMatt Roper1-0/+1
MTL's graphics IP (Xe_LPG) once again changes the multicast register types and steering details. Key changes from past platforms: * The number of instances of some MCR types (NODE, OAAL2, and GAM) vary according to the MTL subplatform and cannot be read from fuse registers. However steering to instance #0 will always provided a non-terminated value, so we can lump these all into a single "instance0" table. * The MCR steering register (and its bitfields) has changed. Unlike past platforms, we will be explicitly steering all types of MCR accesses, including those for "SLICE" and "DSS" ranges; we no longer rely on implicit steering. On previous platforms, various hardware/firmware agents that needed to access registers typically had their own steering control registers, allowing them to perform multicast steering without clobbering the CPU/kernel steering. Starting with MTL, more of these agents now share a single steering register (0xFD4) and it is no longer safe for us to assume that the value will remain unchanged from how we initialized it during startup. There is also a slight chance of race conditions between the driver and a hardware/firmware agent, so the hardware provides a semaphore register that can be used to coordinate access to the steering register. Support for the semaphore register will be introduced in a future patch. v2: - Use Xe_LPG terminology instead of "MTL 3D" since it's the IP version we're matching on now rather than the platform. - Don't combine l3bank and mslice masks into a union. It's not related to the other changes here and we might still need both of them on some future platform. - Separate debug dumping of steering settings to a separate helper function. (Tvrtko) - Update debug dumping to include DSS ranges (and future-proof it so that any new ranges added on future platforms will also be dumped). - Restore MULTICAST bit at the end of rw_with_mcr_steering_fw() if we cleared it. Also force the MULTICAST bit to true at the beginning of multicast writes just to be safe.

2022-10-14drm/i915: enable PS64 support for DG2Matthew Auld1-2/+0
It turns out that on production DG2/ATS HW we should have support for PS64. This feature allows to provide a 64K TLB hint at the PTE level, which is a lot more flexible than the current method of enabling 64K GTT pages for the entire page-table, since that leads to all kinds of annoying restrictions, as documented in: commit caa574ffc4aaf4f29b890223878c63e2e7772f62 Author: Matthew Auld <matthew.auld@intel.com> Date: Sat Feb 19 00:17:49 2022 +0530 drm/i915/uapi: document behaviour for DG2 64K support On discrete platforms like DG2, we need to support a minimum page size of 64K when dealing with device local-memory. This is quite tricky for various reasons, so try to document the new implicit uapi for this. With PS64, we can now drop the 2M GTT alignment restriction, and instead only require 64K or larger when dealing with lmem. We still use the compact-pt layout when possible, but only when we are certain that this doesn't interfere with userspace. Note that this is a change in uAPI behaviour, but hopefully shouldn't be a concern (IGT is at least able to autodetect the alignment), since we are only making the GTT alignment constraint less restrictive. Based on a patch from CQ Tang. v2: update the comment wrt scratch page v3: (Nirmoy) - Fix the selftest to actually use the random size, plus some comment improvements, also drop the rem stuff.

git://anongit.freedesktop.org/drm/drm-intel into drm-next UAPI Changes: - Revert "drm/i915/dg2: Add preemption changes for Wa_14015141709" The intent of Wa_14015141709 was to inform us that userspace can no longer control object-level preemption as it has on past platforms (i.e., by twiddling register bit CS_CHICKEN1[0]). The description of the workaround in the spec wasn't terribly well-written, and when we requested clarification from the hardware teams we were told that on the kernel side we should also probably stop setting FF_SLICE_CS_CHICKEN1[14], which is the register bit that directs the hardware to honor the settings in per-context register CS_CHICKEN1. It turns out that this guidance about FF_SLICE_CS_CHICKEN1[14] was a mistake; even though CS_CHICKEN1[0] is non-operational and useless to userspace, there are other bits in the register that do still work and might need to be adjusted by userspace in the future (e.g., to implement other workarounds that show up). If we don't set FF_SLICE_CS_CHICKEN1[14] in i915, then those future workarounds would not take effect.

However on ATS-M, switching this to "round robin after dependencies" provides better performance. We'll add a new "tuning" feature flag to the ATS-M device info to enable/disable this setting.

MTL introduces a second FBC engine. The two FBC engines can operate entirely independently, FBC A serving pipe A and FBC B serving pipe B. The one place where things might go a bit wrong is the CFB allocation from stolen. We might have to consider some change to the allocation strategy to have a better chance of both engines being able to allocate its CFB. Maybe FBC A should allocate bottom up and FBC B top down, or something? For the moment the allocation strategy is DRM_MM_INSERT_BEST for both.
