sched_ext: Replace SCX_TASK_BAL_KEEP with SCX_RQ_BAL_KEEP
SCX_TASK_BAL_KEEP is used by balance_one() to tell pick_next_task_scx() to keep running the current task. It's not really a task property. Replace it with SCX_RQ_BAL_KEEP which resides in rq->scx.flags and is a better fit for the usage. Also, the existing clearing rule is unnecessarily strict and makes it difficult to use with core-sched. Just clear it on entry to balance_one(). Signed-off-by: Tejun Heo <tj@kernel.org> |

Merge branch 'tip/sched/core' into for-6.12
- Resolve trivial context conflicts from dl_server clearing being moved around. - Add @next to put_prev_task_scx() and @prev to pick_next_task_scx() to match sched/core. - Merge sched_class->switch_class() addition from sched_ext with tip/sched/core changes in __pick_next_task(). - Make pick_next_task_scx() call put_prev_task_scx() to emulate the previous behavior where sched_class->put_prev_task() was called before sched_class->pick_next_task(). While this makes sched_ext build and function, the behavior is not in line with other sched classes. The follow-up patches will address the discrepancies and remove sched_class->switch_class().

sched: Clean up DL server vs core sched
Abide by the simple rule: pick_next_task() := pick_task() + set_next_task(.first = true) This allows us to trivially get rid of server_pick_next() and things collapse nicely.

sched/eevdf: Propagate min_slice up the cgroup hierarchy
In the absence of an explicit cgroup slice configureation, make mixed slice length work with cgroups by propagating the min_slice up the hierarchy. This ensures the cgroup entity gets timely service to service its entities that have this timing constraint set on them.

sched/eevdf: Use sched_attr::sched_runtime to set request/slice suggestion
Allow applications to directly set a suggested request/slice length using
sched_attr::sched_runtime.
The implementation clamps the value to: 0.1[ms] <= slice <= 100[ms]
which is 1/10 the size of HZ=1000 and 10 times the size of HZ=100.
Applications should strive to use their periodic runtime at a high
confidence interval (95%+) as the target slice. Using a smaller slice
will introduce undue preemptions, while using a larger value will
increase latency.
For all the following examples assume a scheduling quantum of 8, and for
consistency all examples have W=4:

Note: 1 heavy task -- because q=8, double r such that the deadline of the w=2
task doesn't go below q.
Note: observe the full schedule becomes: W*max(r_i/w_i) = 4*2q = 8q in length.

From all this it can be deduced that, for the steady state:
- the total period (P) of a schedule is: W*max(r_i/w_i)
- the average period of a task is: W*(r_i/w_i)
- each task obtains the fair share: w_i/W of each full period P

sched/fair: Avoid re-setting virtual deadline on 'migrations'
During OSPM24 Youssef noted that migrations are re-setting the virtual deadline. Notably everything that does a dequeue-enqueue, like setting nice, changing preferred numa-node, and a myriad of other random crap, will cause this to happen. This shouldn't be. Preserve the relative virtual deadline across such dequeue/enqueue cycles.

sched/rt: Clean up usage of rt_task()
rt_task() checks if a task has RT priority. But depends on your dictionary, this could mean it belongs to RT class, or is a 'realtime' task, which includes RT and DL classes. Since this has caused some confusion already on discussion [1], it seemed a clean up is due. I define the usage of rt_task() to be tasks that belong to RT class. Make sure that it returns true only for RT class and audit the users and replace the ones required the old behavior with the new realtime_task() which returns true for RT and DL classes. Introduce similar realtime_prio() to create similar distinction to rt_prio() and update the users that required the old behavior to use the new function. Move MAX_DL_PRIO to prio.h so it can be used in the new definitions. Document the functions to make it more obvious what is the difference between them. PI-boosted tasks is a factor that must be taken into account when choosing which function to use. Rename task_is_realtime() to realtime_task_policy() as the old name is confusing against the new realtime_task(). No functional changes were intended.

sched_ext: Allow p->scx.disallow only while loading
From 1232da7eced620537a78f19c8cf3d4a3508e2419 Mon Sep 17 00:00:00 2001
From: Tejun Heo <tj@kernel.org>
Date: Wed, 31 Jul 2024 09:14:52 -1000
p->scx.disallow provides a way for the BPF scheduler to reject certain tasks
from attaching. It's currently allowed for both the load and fork paths;
however, the latter doesn't actually work as p->sched_class is already set
by the time scx_ops_init_task() is called during fork.
This is a convenience feature which is mostly useful from the load path
anyway. Allow it only from the load path.
v2: Trigger scx_ops_error() iff @p->policy == SCHED_EXT to make it a bit
easier for the BPF scheduler (David).

scx: Allow calling sleepable kfuncs from BPF_PROG_TYPE_SYSCALL
We currently only allow calling sleepable scx kfuncs (i.e. scx_bpf_create_dsq()) from BPF_PROG_TYPE_STRUCT_OPS progs. The idea here was that we'd never have to call scx_bpf_create_dsq() outside of a sched_ext struct_ops callback, but that might not actually be true. For example, a scheduler could do something like the following: 1. Open and load (not yet attach) a scheduler skel 2. Synchronously call into a BPF_PROG_TYPE_SYSCALL prog from user space. For example, to initialize an LLC domain, or some other global, read-only state. 3. Attach the skel, which actually enables the scheduler The advantage of doing this is that it can preclude having to do pretty ugly boilerplate like initializing a read-only, statically sized array of u64[]'s which the kernel consumes literally once at init time to then create struct bpf_cpumask objects which are actually queried at runtime. Doing the above is already possible given that we can invoke core BPF kfuncs, such as bpf_cpumask_create(), from BPF_PROG_TYPE_SYSCALL progs. We already allow many scx kfuncs to be called from BPF_PROG_TYPE_SYSCALL progs (e.g. scx_bpf_kick_cpu()). Let's allow the sleepable kfuncs as well.

sched/core: Fix picking of tasks for core scheduling with DL server
* Use simple CFS pick_task for DL pick_task DL server's pick_task calls CFS's pick_next_task_fair(), this is wrong because core scheduling's pick_task only calls CFS's pick_task() for evaluation / checking of the CFS task (comparing across CPUs), not for actually affirmatively picking the next task. This causes RB tree corruption issues in CFS that were found by syzbot. * Make pick_task_fair clear DL server A DL task pick might set ->dl_server, but it is possible the task will never run (say the other HT has a stop task). If the CFS task is picked in the future directly (say without DL server), ->dl_server will be set. So clear it in pick_task_fair(). This fixes the KASAN issue reported by syzbot in set_next_entity().

sched/deadline: Deferrable dl server
Among the motivations for the DL servers is the real-time throttling mechanism. This mechanism works by throttling the rt_rq after running for a long period without leaving space for fair tasks. The base dl server avoids this problem by boosting fair tasks instead of throttling the rt_rq. The point is that it boosts without waiting for potential starvation, causing some non-intuitive cases. For example, an IRQ dispatches two tasks on an idle system, a fair and an RT. The DL server will be activated, running the fair task before the RT one. This problem can be avoided by deferring the dl server activation. By setting the defer option, the dl_server will dispatch an SCHED_DEADLINE reservation with replenished runtime, but throttled. The dl_timer will be set for the defer time at (period - runtime) ns from start time. Thus boosting the fair rq at defer time. If the fair scheduler has the opportunity to run while waiting for defer time, the dl server runtime will be consumed. If the runtime is completely consumed before the defer time, the server will be replenished while still in a throttled state. Then, the dl_timer will be reset to the new defer time If the fair server reaches the defer time without consuming its runtime, the server will start running, following CBS rules (thus without breaking SCHED_DEADLINE). Then the server will continue the running state (without deferring) until it fair tasks are able to execute as regular fair scheduler (end of the starvation).

Pull CXL updates from Dave Jiang:
"Core:
- A CXL maturity map has been added to the documentation to detail
the current state of CXL enabling.
It provides the status of the current state of various CXL features
to inform current and future contributors of where things are and
which areas need contribution.
- A notifier handler has been added in order for a newly created CXL
memory region to trigger the abstract distance metrics calculation.
This should bring parity for CXL memory to the same level vs
hotplugged DRAM for NUMA abstract distance calculation. The
abstract distance reflects relative performance used for memory
tiering handling.
- An addition for XOR math has been added to address the CXL DPA to
SPA translation.
CXL address translation did not support address interleave math
with XOR prior to this change.
Fixes:
- Fix to address race condition in the CXL memory hotplug notifier
- Add missing MODULE_DESCRIPTION() for CXL modules
- Fix incorrect vendor debug UUID define
Misc:
- A warning has been added to inform users of an unsupported
configuration when mixing CXL VH and RCH/RCD hierarchies
- The ENXIO error code has been replaced with EBUSY for inject poison
limit reached via debugfs and cxl-test support
- Moving the PCI config read in cxl_dvsec_rr_decode() to avoid

Rust changes for v6.11
The highlight is the establishment of a minimum version for the Rust toolchain, including 'rustc' (and bundled tools) and 'bindgen'. The initial minimum will be the pinned version we currently have, i.e. we are just widening the allowed versions. That covers 3 stable Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta, plus nightly. This should already be enough for kernel developers in distributions that provide recent Rust compiler versions routinely, such as Arch Linux, Debian Unstable (outside the freeze period), Fedora Linux, Gentoo Linux (especially the testing channel), Nix (unstable) and openSUSE Slowroll and Tumbleweed. In addition, the kernel is now being built-tested by Rust's pre-merge CI. That is, every change that is attempting to land into the Rust compiler is tested against the kernel, and it is merged only if it passes. Similarly, the bindgen tool has agreed to build the kernel in their CI too. Thus, with the pre-merge CI in place, both projects hope to avoid unintentional changes to Rust that break the kernel. This means that, in general, apart from intentional changes on their side (that we will need to workaround conditionally on our side), the upcoming Rust compiler versions should generally work. In addition, the Rust project has proposed getting the kernel into stable Rust (at least solving the main blockers) as one of its three flagship goals for 2024H2 [1]. I would like to thank Niko, Sid, Emilio et al. for their help promoting the collaboration between Rust and the kernel. [1] https://rust-lang.github.io/rust-project-goals/2024h2/index.html#flagship-goals Toolchain and infrastructure: - Support several Rust toolchain versions. - Support several bindgen versions. - Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc' having been dropped last cycle. - Provide proper error reporting for the 'rust-analyzer' target. 'kernel' crate: - Add 'uaccess' module with a safe userspace pointers abstraction. - Add 'page' module with a 'struct page' abstraction. - Support more complex generics in workqueue's 'impl_has_work!' macro. 'macros' crate: - Add 'firmware' field support to the 'module!' macro. - Improve 'module!' macro documentation. Documentation: - Provide instructions on what packages should be installed to build the kernel in some popular Linux distributions. - Introduce the new kernel.org LLVM+Rust toolchains. - Explain '#[no_std]'.

firewire fixes for 6.11-rc1
Two commits are included to fix some regressions. These commits should also be applied to the v6.10 kernel as well. The recent integration of compiler collections introduced the technology to check flexible array length at runtime by providing proper annotations. In v6.10 kernel, a patch was merged into firewire subsystem to utilize it, however the annotation was inadequate. There is also the related change for the flexible array in sound subsystem, but it causes a regression where the data in the payload of isochronous packet is incorrect for some devices. These bugs are now fixed. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQQE66IEYNDXNBPeGKSsLtaWM8LwEwUCZqRPbgAKCRCsLtaWM8Lw E4IDAQCr4s3/W1fwkUcxvaFKn4ngELXtZ8D2BtI0I3x+axOvggEA4NhtbSwusyKK r3Zsyf8r9WrzIOMFASqqV7LlaiWTogI= =eq44 -----END PGP SIGNATURE----- Merge tag 'firewire-fixes-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fixes from Takashi Sakamoto: "The recent integration of compiler collections introduced the technology to check flexible array length at runtime by providing proper annotations.

Fixes and minor updates for the timer migration code:
- Stop testing the group->parent pointer as it is not guaranteed to be
stable over a chain of operations by design. This includes a warning
which would be nice to have but it produces false positives due to
the racy nature of the check.
- Plug a race between CPUs going in and out of idle and a CPU hotplug
operation. The latter can create and connect a new hierarchy level
which is missed in the concurrent updates of CPUs which go into idle.
As a result the events of such a CPU might not be processed and
timers go stale.
Cure it by splitting the hotplug operation into a prepare and online
callback. The prepare callback is guaranteed to run on an online and
therefore active CPU. This CPU updates the hierarchy and being online
ensures that there is always at least one migrator active which
handles the modified hierarchy correctly when going idle. The online
callback which runs on the incoming CPU then just marks the CPU
active and brings it into operation.
- Improve tracing and polish the code further so it is more obvious
what's going on.

minmax: avoid overly complicated constant expressions in VM code
The minmax infrastructure is overkill for simple constants, and can cause huge expansions because those simple constants are then used by other things. For example, 'pageblock_order' is a core VM constant, but because it was implemented using 'min_t()' and all the type-checking that involves, it actually expanded to something like 2.5kB of preprocessor noise. And when that simple constant was then used inside other expansions: #define pageblock_nr_pages (1UL << pageblock_order) #define pageblock_start_pfn(pfn) ALIGN_DOWN((pfn), pageblock_nr_pages) and we then use that inside a 'max()' macro: case ISOLATE_SUCCESS: update_cached = false; last_migrated_pfn = max(cc->zone->zone_start_pfn, pageblock_start_pfn(cc->migrate_pfn - 1)); the end result was that one statement expanding to 253kB in size. There are probably other cases of this, but this one case certainly stood out. I've added 'MIN_T()' and 'MAX_T()' macros for this kind of "core simple constant with specific type" use. These macros skip the type checking, and as such need to be very sparingly used only for obvious cases that have active issues like this.

alloc_tag: outline and export free_reserved_page()
Outline and export free_reserved_page() because modules use it and it in
turn uses page_ext_{get|put} which should not be exported. The same
result could be obtained by outlining {get|put}_page_tag_ref() but that
would have higher performance impact as these functions are used in more
performance critical paths.

io_uring/napi: use ktime in busy polling
It's more natural to use ktime/ns instead of keeping around usec, especially since we're comparing it against user provided timers, so convert napi busy poll internal handling to ktime. It's also nicer since the type (ktime_t vs unsigned long) now tells the unit of measure. Keep everything as ktime, which we convert to/from micro seconds for IORING_[UN]REGISTER_NAPI. The net/ busy polling works seems to work with usec, however it's not real usec as shift by 10 is used to get it from nsecs, see busy_loop_current_time(), so it's easy to get truncated nsec back and we get back better precision. Note, we can further improve it later by removing the truncation and maybe convincing net/ to use ktime/ns instead.

Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:
- platform remove callback api final fixups (Uwe took many releases to
get here, finally!)
- Rust bindings for basic firmware apis and initial driver-core
interactions. It's not all that useful for a "write a whole driver
in rust" type of thing, but the firmware bindings do help out the
phy rust drivers, and the driver core bindings give a solid base on
which others can start their work. There is still a long way to go
here before we have a multitude of rust drivers being added, but
it's a great first step.
- driver core const api changes. This reached across all bus types,
and there are some fix-ups for some not-common bus types that
linux-next and 0-day testing shook out. This work is being done to
help make the rust bindings more safe, as well as the C code, moving
toward the end-goal of allowing us to put driver structures into
read-only memory. We aren't there yet, but are getting closer.
- minor devres cleanups and fixes found by code inspection
- arch_topology minor changes
- other minor driver core cleanups
All of these have been in linux-next for a very long time with no
reported problems.

of: remove internal arguments from of_property_for_each_u32()
The of_property_for_each_u32() macro needs five parameters, two of which
are primarily meant as internal variables for the macro itself (in the
for() clause). Yet these two parameters are used by a few drivers, and this
can be considered misuse or at least bad practice.
Now that the kernel uses C11 to build, these two parameters can be avoided
by declaring them internally, thus changing this pattern:
struct property *prop;
const __be32 *p;
u32 val;
of_property_for_each_u32(np, "xyz", prop, p, val) { ... }
to this:
u32 val;
of_property_for_each_u32(np, "xyz", val) { ... }
However two variables cannot be declared in the for clause even with C11,
so declare one struct that contain the two variables we actually need. As
the variables inside this struct are not meant to be used by users of this
macro, give the struct instance the noticeable name "_it" so it is visible
during code reviews, helping to avoid new code to use it directly.
Most usages are trivially converted as they do not use those two
parameters, as expected. The non-trivial cases are:
- drivers/clk/clk.c, of_clk_get_parent_name(): easily doable anyway
- drivers/clk/clk-si5351.c, si5351_dt_parse(): this is more complex as the
checks had to be replicated in a different way, making code more verbose
and somewhat uglier, but I refrained from a full rework to keep as much
of the original code untouched having no hardware to test my changes
All the changes have been build tested. The few for which I have the
hardware have been runtime-tested too.
