The implementation of Wa_22011450934 introduced three new register definitions in i915_reg.h that didn't get moved to the GT/engine register headers when all the other registers moved; let's move them to the appropriate headers and tidy up their definitions now for consistency: - STATE_ACK_DEBUG is moved to the engine register header and converted to a parameterized definition; the workaround only needs the RCS instance to be programmed, but there are instances on other engines that could be used by other workarounds in the future. - The two CULLBIT registers move to the GT register header. Since they belong to MMIO ranges that became MCR starting with Xe_HP, their definitions should be defined as MCR_REG() and use an Xe_HP prefix to keep the register semantics clear. Note that the MCR definition is just for consistency and to prevent accidental misuse if other workarounds related to these registers show up in the future. There's no functional change to today's driver since the workaround that references these registers only accesses them via MI_LRR engine instructions. Engine-initiated register accesses do not utilize the same steering controls as CPU-initiated accesses; they use a different steering control register (0x20CC) which is initialized to a non-terminated DSS target by pre-OS firmware and never changed thereafter (i915 does not touch it and userspace does not have permission to change that register).

When trying to analyse bug reports from CI, customers, etc. it can be difficult to work out exactly what is happening on which GT in a multi-GT system. So add GT oriented debug/error message wrappers. If used instead of the drm_ equivalents, you get the same output but with a GT# prefix on it. v2: Go back to using lower case names (combined review feedback). Convert intel_gt.c as a first step. v3: Add gt_err_ratelimited() as well, undo one conversation that might not have a GT pointer in some scenarios (review feedback from Michal W). Split definitions into separate header (review feedback from Jani). Convert all intel_gt*.c files. v4: Re-order some macro definitions (Andi S), update (c) date (Tvrtko) Signed-off-by:

If PXP arb-session is being attempted on older hardware SKUs or on hardware with older, unsupported, firmware versions, then don't report the failure with a drm_error. Instead, look specifically for the API-version error reply and drm_dbg that reply. In this case, the user-space will eventually get a -ENODEV for the protected context creation which is the correct behavior and we don't create unnecessary drm_error's in our dmesg (for what is unsupported platforms). Changes from prio revs: v2 : - remove unnecessary newline. (Jani) v1 : - print incorrect version from input packet, not output. Signed-off-by:

Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays in a couple of structures (three, actually) with flex-array members. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].

After applying an engine reset, on some platforms like Jasperlake, we occasionally detect that the engine state is not cleared until shortly after the resume. As we try to resume the engine with volatile internal state, the first request fails with a spurious CS event (it looks like it reports a lite-restore to the hung context, instead of the expected idle->active context switch).

HW allows arbitrary PL1 limits to be set but silently clamps these values to "typical but not guaranteed" min/max values in pkg_power_sku register. Follow the same pattern for sysfs, allow arbitrary PL1 limits to be set but display clamped values when read, so that users see PL1 limits HW is likely using. Otherwise users think HW is using arbitrarily high/low PL1 limits they might have set. The previous write/read I1 power1_crit limit also follows the same clamping pattern. v2: Explain "why" in commit message and include bug link (Jani Nikula) Bug: https://gitlab.freedesktop.org/drm/intel/-/issues/7704Signed-off-by:

There is an impedance mismatch between the scatterlist API using unsigned int and our memory/page accounting in unsigned long. That is we may try to create a scatterlist for a large object that overflows returning a small table into which we try to fit very many pages. As the object size is under the control of userspace, we have to be prudent and catch the conversion errors. To catch the implicit truncation we check before calling scattterlist creation Apis. we use overflows_type check and report E2BIG if the overflows may raise. When caller does not return errno, use WARN_ON to report a problem. This is already used in our create ioctls to indicate if the uABI request is simply too large for the backing store. Failing that type check, we have a second check at sg_alloc_table time to make sure the values we are passing into the scatterlist API are not truncated. v2: Move added i915_utils's macro into drm_util header (Jani N) v5: Fix macros to be enclosed in parentheses for complex values Fix too long line warning v8: Replace safe_conversion() with check_assign() (Kees) v14: Remove shadowing macros of scatterlist creation api and fix to explicitly overflow check where the scatterlist creation APIs are called.

We need to check that we avoid integer overflows when looking up a page, and so fix all the instances where we have mistakenly used a plain integer instead of a more suitable long. Be pedantic and add integer typechecking to the lookup so that we can be sure that we are safe.

Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/Signed-off-by:Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by:

If mem-type is specified in the device tree it would end up overriding the record_size field instead of populating mem_type. As record_size is currently parsed after the improper assignment with default size 0 it continued to work as expected regardless of the value found in the device tree. Simply changing the target field of the struct is enough to get mem-type working as expected.

In commit 76d62f24 ("pstore: Switch pmsg_lock to an rt_mutex to avoid priority inversion") I changed a lock to an rt_mutex. However, its possible that CONFIG_RT_MUTEXES is not enabled, which then results in a build failure, as the 0day bot detected: https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/ Thus this patch changes CONFIG_PSTORE_PMSG to select CONFIG_RT_MUTEXES, which ensures the build will not fail.

When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a CFI type hash for asan.module_ctor functions in translation units where CFI is disabled, which leads to a CFI failure during boot when do_ctors calls the affected constructors: CFI failure at do_basic_setup+0x64/0x90 (target: asan.module_ctor+0x0/0x28; expected type: 0xa540670c) Specifically, this happens because CFI is disabled for kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so fix the failure by not filtering out CC_FLAGS_CFI for the file. Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue where LLVM didn't emit CFI type hashes for any sanitizer constructors, but now type hashes are emitted correctly for TUs that use CFI.
