Intel hardware allows some preemption settings to be controlled either by the kernel-mode driver exclusively, or placed under control of the user-mode drivers; on Linux we always select the userspace control option. The various registers involved in this are not documented very clearly; let's add some clarifying comments to help explain how this all works and provide some history on why our Linux drivers take the approach they do (which I believe differs from the path taken by certain other operating systems' drivers). While we're at it, let's also remove the graphics version 12 upper bound on this programming. As described, we don't have any plans to move away from UMD control of preemption settings on future platforms, and there's currently no reason to believe that the hardware will fundamentally change how these registers and settings work after version 12.

It looks like we need this for local-memory, if we want to use ptrace. Something more is still needed if we want to handle non-mappable memory, which looks quite annoying. v2: - ttm_bo_kmap doesn't seem to work well here, and seems to expect contiguous resource. v3(Andi): - s/PAGE_SIZE/bytes/ when passing in the size of the mapping.

The fw name is different and we need to record the fact that the blob is gsc-loaded, so add a new macro to help. Note: A-step DG2 G10 does not support HuC loading via GSC and would require a separate firmware to be loaded the legacy way, but that's not a production stepping so we're not going to bother. v2: rebase on new fw fetch logic Signed-off-by:

The current HuC status getparam return values are a bit confusing in regards to what happens in some scenarios. In particular, most of the error cases cause the ioctl to return an error, but a couple of them, INIT_FAIL and LOAD_FAIL, are not explicitly handled and neither is their expected return value documented; these 2 error cases therefore end up into the catch-all umbrella of the "HuC not loaded" case, with this case therefore including both some error scenarios and the load in progress one. The updates included in this patch change the handling so that all error cases behave the same way, i.e. return an errno code, and so that the HuC load in progress case is unambiguous. The patch also includes a small change to the FW init path to make sure we always transition to an error state if something goes wrong. Signed-off-by:

Daniele Ceraolo Spurio authored
Given that HuC load is delayed on DG2, this patch adds support for a fence that can be used to wait for load completion. No waiters are added in this patch (they're coming up in the next one), to keep the focus of the patch on the tracking logic. The full HuC loading flow on boot DG2 is as follows: 1) i915 exports the GSC as an aux device; 2) the mei-gsc driver is loaded on the aux device; 3) the mei-pxp component is loaded; 4) mei-pxp calls back into i915 and we load the HuC. Between steps 1 and 2 there can be several seconds of gap, mainly due to the kernel doing other work during the boot. The resume flow is slightly different, because we don't need to re-expose or re-probe the aux device, so we go directly to step 3 once i915 and mei-gsc have completed their resume flow. Here's an example of the boot timing, captured with some logs added to i915: [ 17.908307] [drm] adding GSC device [ 17.915717] [drm] i915 probe done [ 22.282917] [drm] mei-gsc bound [ 22.938153] [drm] HuC authenticated Also to note is that if something goes wrong during GSC HW init the mei-gsc driver will still bind, but steps 3 and 4 will not happen. The status tracking is done by registering a bus_notifier to receive a callback when the mei-gsc driver binds, with a large enough timeout to account for delays. Once mei-gsc is bound, we switch to a smaller timeout to wait for the mei-pxp component to load. The fence is signalled on HuC load complete or if anything goes wrong in any of the tracking steps. Timeout are enforced via hrtimer callbacks. v2: fix includes (Jani) v5: gsc_notifier() remove unneeded () Signed-off-by:

The GSC will perform both the load and the authentication, so we just need to check the auth bit after the GSC has replied. Since we require the PXP module to load the HuC, the earliest we can trigger the load is during the pxp_bind operation. Note that GSC-loaded HuC survives GT reset, so we need to just mark it as ready when we re-init the GT HW. V2: move setting of HuC fw error state to the failure path of the HuC auth function, so it covers both the legacy and new auth flows V4: 1.

Vitaly Lubart authored
Command to be sent via the stream interface are written to a local memory page, whose address is then provided to the GSC. The interface supports providing a full sg with multiple pages for both input and output messages, but since for now we only aim to support short and synchronous messages we can use a single page for both input and output. Note that the mei interface expects an sg of 4k pages, while our lmem pages are 64k. If we ever need to support more than 4k we'll need to convert. Added a TODO comment to the code to record this.

Lucas De Marchi authored
ce->wa_bb_page is allocated only for graphics version 12. However __gen125_emit_bb_start() is used for any graphics version >= 12.50. For the currently supported platforms this is not an issue, but for future ones there's a mismatch causing the jump to `wa_offset + DG2_PREDICATE_RESULT_BB` to be invalid since wa_offset is not correct. As in other places in the driver, check for graphics version "greater or equal" to future-proof the support for new platforms.

As an integrated GPU, MTL does not have local memory and HAS_LMEM() returns false. However the platform's stolen memory is presented via BAR2 (i.e., the BAR we traditionally consider to be the GMADR on IGFX) and should be managed by the driver the same way that local memory is on dgpu platforms (which includes setting the "lmem" bit on page table entries). We use the term "local stolen memory" to refer to this model. The major difference from the traditional BAR2 (GMADR) is that the stolen area is mapped via the BAR2 while in the former BAR2 is an aperture into the GTT VA through which access are made into stolen area. BSPEC: 53098, 63830 v2: 1. dropped is_dsm_invalid, updated valid_stolen_size check from Lucas (Jani, Lucas) 2. drop lmembar_is_igpu_stolen 3. revert to referring GFXMEM_BAR as GEN12_LMEM_BAR (Lucas) v3:(Jani) 1. rename get_mtl_gms_size to mtl_get_gms_size 2. define register for MMIO address v4:(Matt) 1.

The part of the media and blitter engine contexts that we care about for setting up an initial state on MTL are nearly similar to DG2 (and PVC). The difference being PRT_BB_STATE being replaced with NOP. For render/compute engines, the part of the context images are nearly the same, although the layout had a very slight change --- one POSH register was removed and the placement of some LRI/noops adjusted slightly to compensate. v2: - Dg2, mtl xcs offsets slightly vary.

DG2 has issues. To work around one of these the GuC must schedule apps in an exclusive manner across both RCS and CCS. That is, if a context from app X is running on RCS then all CCS engines must sit idle even if there are contexts from apps Y, Z, ... waiting to run. A certain OS favours RCS to the total starvation of CCS. Linux does not. Hence the GuC now has a scheduling policy setting to control this abitration. Signed-off-by:

If attempting to perform a GT reset takes long than 5 seconds (including resetting the display for gen3/4), then we declare all hope lost and discard all user work and wedge the device to prevent further misbehaviour. 5 seconds is too short a time for such drastic action, as we may be stuck on other timeouts and watchdogs. If we allow a little bit longer before hitting the big red button, we should at the very least capture other hung task indicators pointing towards the reason why the reset was hanging; and allow more marginal cases the extra headroom to complete the reset without further collateral damage.
