Cleanup gt and display wrt the comments for the workarounds. Rationale
is in the patch itself.
I'm providing the patches, as generated by the commands in the commit
message, with a fixup on top to remove false positives. The intention for
when this is ready to be applied is to squash the fixup: it's only
provided for ease of review and rebase.

False positives we can fixup, false negatives we simply don't see. After running that in gt/: $ git grep ": mtl" -- drivers/gpu/drm/i915/ drivers/gpu/drm/i915/gt/intel_gt_pm.c: /* Wa_14017073508: mtl */ drivers/gpu/drm/i915/gt/intel_gt_pm.c: /* Wa_14017073508: mtl */ drivers/gpu/drm/i915/gt/intel_gt_pm.c: /* Wa_14017073508: mtl */ drivers/gpu/drm/i915/gt/intel_gt_pm.c: /* Wa_14017073508: mtl */ drivers/gpu/drm/i915/gt/uc/intel_guc_rc.c: * Wa_14017073508: mtl drivers/gpu/drm/i915/i915_reg.h:/* Wa_14017210380: mtl */ I was going with the platform names to avoid the false negatives and because I was entertaining the idea of only doing this for latest platforms where we do have the "Wa_[[:number:]]" form > >Maybe.. > >Matt recently said he has this worked planned, but more importantly - >I gather then that the WA lookup tool definitely does not output these >strings? Whatever it does it's true only at the time it's called. It simply tells what are the platforms and steppings the Wa applies to. We can change the output to whatever we want, but that is not the point. Those comments get stale and bring no real value as they match 1:1 what the code is supposed to be doing. Several times a patch has to update just that comment to "extend a workaround" to a next platform. This is not always done, so we get a comment that doesn't match what is supposed to be there.

Tl;dr; version - lets park this until January and discuss once everyone is back. Longer version. I've been trying to get us talking about this a couple times before and I'd really like to close with an explicit consensus, discussion points addressed instead of skipped and just moving ahead with patches. References: 3fcf71b9-337f-6186-7b00-27cbfd116743@linux.intel.com Y5j0b/bykbitCa4Q@mdroper-desk1.amr.corp.intel.com So point I wanted to discuss is whether these comments are truly useless or maybe they can help during review. If the tool can actually output them then I am leaning towards that they can be. Thought is, when a patch comes for review adding a new platform, stepping, whatever, to an existing if condition, if it contains the comments reviewer can more easily spot a hyphotetical logic inversion error or similar. It is also trivial to check that both condition and comment have been updated. (So lets not be rash and remove something maybe useful just because it can go stale *only if* reviewers are not giving sufficient attention that changes are made in tandem.) From a slightly different angle - do we expect anyone reviewing workaround patches will cross-check against the tool? Would it be simpler and more efficient that they could just cross-check against the comment output from the tool and put into the patch by the author? And point here to stress out is that accidental logic errors (missed workarounds) can be super expensive to debug in the field. Sometimes it can literally take _months_ for sporadic and hard to reproduce issues to get debugged, handed over between the teams, etc. So any way in which we can influence the likelyhood of that happening is something to weigh carefully. Secondary but also important - if i915 is end of line then an extra why we want to rip out this for ancient platforms. Is the cost/benefit positive there? As a side note, and going back to the question of what the tool can output. Long time ago I had an idea where we could improve all this by making it completely data-driven. Have the WA database inspecting tool output a table which could be directly pasted into code and interpreted by i915. For reference look at intel_workarounds_table.h in https://patchwork.freedesktop.org/patch/399377/?series=83580&rev=3 and see what you thing. That was just a sketch of the idea, not complete, and yes, i915 end of life point makes it moot. Regards, Tvrtko ^ permalink raw reply [flat|nested] 19+ messages in thread

I can argue to the other side too. We don't have comments in the kernel like /* Add 1 to i */ i += 1; This is exactly what these comments are doing. And they are misleading and may introduce bugs rather than helping reviewing: Wa_12345:tgl[a0,c0) if (IS_TGL_GRAPHICS_STEP(STEP_A0, STEP_B0) One might read the comment, skipping over the condition and thinking "ok, we already extended this WA to B* steppings, which doesn't match the code. >From a slightly different angle - do we expect anyone reviewing >workaround patches will cross-check against the tool?

And they are misleading Yeah, this is exactly my feeling for why the platform/steppings should just be removed from the comments. Keeping the workaround numbers is useful for quickly jumping to the implementation(s) of the workaround in the code with grep, but everything else is (at best) just re-stating exactly what the next lines of code should say. During review, the code itself is what really matters, and comments (which might become stale or incorrect) just make it easier for mistakes to get overlooked. I haven't reviewed the patch in detail, but from my point of view, Acked-by: Matt Roper <matthew.d.roper@intel.com> on the general direction here.

As I said, it happens more on early enabling of a platform. ... my point which seems to have been missed by both, well question really, do you expect every reviewer to cross-check against the WA database when reviewing WA changes? I don't see that was answered. I guarantee that it won't happen and people will rubber stamp. So my argument was that we could make it both easier for reviewers *and* decrease the likelyhood of misses, if we kept platforms designators in comments. Yeah it is much easier to rip them out that to find and fix the ones which went out of sync but that shouldn't be high on the list of criteria. Argument that it is easy to overlook during review that comments and code do not match I don't think holds. That describes a very sloppy review. And if review is assumed to be that sloppy, do you really trust review to check against the WA database? So my argument is that it is trivial for reviewers to spot comments and code do not match. Trivial and fast. And it's trivial (I hope) for the WA tool to output the right format for pasting in comments. Those are the points I would like to have explicitly discounted before proceeding. Maybe to be even clearer the workflow would be like this: Patch author: 1. Runs the WA tool for a WA number. Tool outputs text. 2. Pastes text verbatim in the comment. 3. Adjusts code to match. Reviewer: 1. Verifies both code and comment were changed. 2. Verifies code matches the comment. If the counter proposal is, patch author: 1. Runs the WA tool for a WA number. Tool outputs text. 2. Adjusts code to match. Reviewer: 1. Runs the WA tool. Tool outputs text. 2. Checks patch matchs the WA tool output. I will accept it but I strongly believe skipping of step 2 will happen and it will be impossible to know. Rubber stamping with the options of comments+code at least leaves a trace of comment and code being out of sync. >> And point here to stress out is that accidental logic errors (missed >> workarounds) can be super expensive to debug in the field.

I think this is the source of the confusion; the comment lines in i915 are not something the 'wa' tool outputs directly; the comments are written manually by the developer at the same time the code is written; the wa tool is just a quick python script I wrote one day to dump database information from the command line and avoid needing to fire up a web browser and click through a series of slow website links. Also, since the wa tool queries internal databases, it spits out a bunch of Intel-internal terminology that doesn't match the terminology used in i915 code, and it also includes a bunch of garbage data that needs to be filtered out (duplicated records, mangled/incomplete records, etc.). Exactly how things are expressed (platform name like "DG2" or IP name like "Xe_HPG" also varies from platform to platform according to how the hardware guys decided to categorize things). Since the code and the comments are both something written by hand by the developer, there's no reason to believe the comments will be more accurate than the code. They'll likely be far less accurate since they can't be tested like the code is, and because the existing codebase is wildly inconsistent with how we even format/represent them. > > > > see above.

Yes, reviewers are absolutely supposed to be checking the stepping bounds of every workarounds change they review. That's one of the most important parts of reviewing a workaround and it should be very quick and easy to do. If people are giving rubber stamps without doing that, then they're not really doing a full review. But I'm also not aware of any cases where we're getting rubber stamps; most of the non-comment review misses we have seem to either come from misunderstanding the semantics of platforms (especially cases like DG2 where different G10/G11/G12 variants have different stepping schemes) or technical misunderstanding of the implementation details (register reset characteristics, masked vs non-masked registers, context membership, etc.). > > Yeah it is much easier to rip them out that to find and fix the ones which > went out of sync but that shouldn't be high on the list of criteria. > > Argument that it is easy to overlook during review that comments and code do > not match I don't think holds. That describes a very sloppy review. And if > review is assumed to be that sloppy, do you really trust review to check > against the WA database? It's the same reason people who write prose can't find their own spelling/grammer mistakes. The mistakes are "obvious," but since their brain already knows what it's "supposed" to say, they just can't see the error themselves. Once you've reviewed the code, it just gets really hard to see where the comment doesn't align, especially for the workarounds that apply to a bunch of platforms. For example, if I'm reviewing a patch that adds: /* Wa_12345:tgl,dg1[a0],rkl,adls,dg2_g10,dg2_g12[a0..c0) */ if (IS_TIGERLAKE(i915) || IS_DG1(i915) || IS_ROCKETLAKE(i915) || IS_ALDERLAKE_P(i915) || IS_DG2_G10(i915) || IS_DG2_GRAPHICS_STEP(i915, G12, STEP_A0, STEP_C0)) I'm always looking at the code first and comparing that to the workaround database. If I then review the comment second, I'm much less likely to catch the subtle errors (there are two of them in this example where the code and comment don't match!) because I mentally already know what the bounds are "supposed" to be and the comment all just kind of blends together. > > So my argument is that it is trivial for reviewers to spot comments and code > do not match. Trivial and fast. And it's trivial (I hope) for the WA tool to > output the right format for pasting in comments. Given how much terminology mismatch there is between the internal database and how we refer to things in i915 code, it's not trivial. It's also not super easy to even figure out which platforms to include in the list. The workaround database is going to include platforms for which there is no i915 support (e.g., LKF) stuff like CNL (support already removed from i915), and future/potential platforms we can't talk about yet, etc. Finally, when there are duplicated/conflicting records (because the people inputting the information are just human too), it takes a bit of human intelligence to read between the lines and figure out what the reality is supposed to be. Sure, these problems could probably all be solved with enough effort, but given how often the internal formatting and behavior of the database itself changes, it would be painful to keep it always working properly. > > Those are the points I would like to have explicitly discounted before > proceeding.

Given everything above lets say we concluded it is too costly to make the tool output the exact format wanted by i915 and we decide to proceed removing the platform designations. Two final questions. Question 1) Is everyone okay to remove from _all_, including old legacy platforms? ROI vs churn considerations? And yes it wouldn't be ideal either to have separate rules with some cutover point like Gen8 maybe. Question 2) For Xe you still intend to have it a manual process and not have the tool output the macro section which could be directly pasted in the code? Would ROI of extending the tool be any better with the data-driven design like there? Regards, Tvrtko > > > Matt > >> 3. Adjusts code to match. >> >> Reviewer: >> >> 1.

For the really old, pre-number workarounds ("Wa_SomeCamelCaseName") I don't have a strong feeling either way. Since those aren't part of the modern workaround database, they're also never going to be updated to add new platforms so if people want to just leave them be that's fine with me. We can see which way Lucas is leaning when he gets back. > > Question 2) > > For Xe you still intend to have it a manual process and not have the tool > output the macro section which could be directly pasted in the code?

The full workaround implementation (register offset, register bits, etc.) definitely can't be auto-generated by a tool since the workaround database itself is just free-form text written by some hardware engineer. There's no standard format they write those in; sometimes they give an offset/bit number, sometimes they give a register name and we have to look up the offset ourselves, sometimes they just give a hyperlink to the bspec page. Generating the platforms/steppings part of a workaround definition is theoretically possible in the same way it would be theoretically possible to generate code comments. But given the realities of the internal database (which is something the hardware people control and like to frequently refactor) it would be a non-trivial amount of work to get to exactly the behavior we want, and our tool would need frequent updates to keep up with the kinds of changes the hardware people tend to make. It's something we can consider, but it isn't something we'll be able to just whip up in an afternoon like the current tool was. Matt > > Regards, > > Tvrtko > > > > > > > Matt > > > > > 3.

It can print anything you want. If someone wants to print the exact code and comment to be added in i915, it could be turned into that with a fair amount of look up tables to translate platform names/steppings/etc, adapt to terminology changes as they come, etc. The fact that would make someone's life miserable and they would probably quit their job is implicit here.

I find this: /* Wa_12345:tgl,dg1[a0],rkl,adls,dg2_g10,dg2_g12[a0..c0) */ Much easier to mentally parse that this: if (IS_TIGERLAKE(i915) || IS_DG1(i915) || IS_ROCKETLAKE(i915) || IS_ALDERLAKE_P(i915) || IS_DG2_G10(i915) || IS_DG2_GRAPHICS_STEP(i915, G12, STEP_A0, STEP_C0)) Let's call it a difference then. And I really think writer's handicap cannot be used to discharge responsibility from reviewers becuase then you kind of nerf the whole concept of proof readers and reviewers. Yes mistakes can happen, but it's those people trained mindset to minimize that. Not to say of lets not bother becuase writers handicap.. Anyway, irrelevant, moving on still.. >>> For example, if I'm reviewing a patch that adds: >>> >>> /* Wa_12345:tgl,dg1[a0],rkl,adls,dg2_g10,dg2_g12[a0..c0) */ >>> if (IS_TIGERLAKE(i915) || IS_DG1(i915) || IS_ROCKETLAKE(i915) || >>> IS_ALDERLAKE_P(i915) || IS_DG2_G10(i915) || >>> IS_DG2_GRAPHICS_STEP(i915, G12, STEP_A0, STEP_C0)) >>> >>> I'm always looking at the code first and comparing that to the >>> workaround database.

At this point, since that plan would affects the whole driver, I think you need to get acks from other maintainers. My view is that on balance, every potential option has pros and cons, and my main thought is that focus should be on any solution which minimizes the amount of missed or misplaces workarounds per platform.
