2023-12-21drm/xe: Correlate engine and cpu timestamps with better accuracyUmesh Nerlige Ramappa1-24/+80
Perf measurements rely on CPU and engine timestamps to correlate events of interest across these time domains. Current mechanisms get these timestamps separately and the calculated delta between these timestamps lack enough accuracy. To improve the accuracy of these time measurements to within a few us, add a query that returns the engine and cpu timestamps captured as close to each other as possible.

2023-12-21drm/xe/uapi: add the userspace bits for small-barMatthew Auld1-1/+46
Mostly the same as i915. We add a new hint for userspace to force an object into the mappable part of vram. We also need to tell userspace how large the mappable part is. In Vulkan for example, there will be two vram heaps for small-bar systems. And here the size of each heap needs to be known. Likewise the used/avail tracking needs to account for the mappable part. We also limit the available tracking going forward, such that we limit to privileged users only, since these values are system wide and are technically considered an info leak. v2 (Maarten): - s/NEEDS_CPU_ACCESS/NEEDS_VISIBLE_VRAM/ in the uapi. We also no longer require smem as an extra placement. This is more flexible, and lets us use this for clear-color surfaces, since we need CPU access there but we don't want to attach smem, since that effectively disables CCS from kernel pov. - Reject clear-color CCS buffers where NEEDS_VISIBLE_VRAM is not set, instead of migrating it behind the scenes. v3 (José): - Split the changes that limit the accounting for perfmon_capable() into a separate patch. - Use XE_BO_CREATE_VRAM_MASK. v4 (Gwan-gyeong Mun): - Add some kernel-doc for the query bits. v5: - One small kernel-doc correction. The cpu_visible_size and corresponding used tracking are always zero for non XE_MEM_REGION_CLASS_VRAM. v6: - Without perfmon_capable() it likely makes more sense to report as zero, instead of reporting as used == total size. This should give similar behaviour as i915 which rather tracks free instead of used. - Only enforce NEEDS_VISIBLE_VRAM on rc_ccs_cc_plane surfaces when the device is actually small-bar.

2023-12-21drm/xe: Use nanoseconds instead of jiffies in uapi for user fenceZbigniew Kempczyński1-2/+14
Using jiffies as a timeout from userspace is weird even if theoretically exists possiblity of acquiring jiffies via getconf. Unfortunately this method is unreliable and the returned value may vary from the one configured in the kernel config. Now timeout is expressed in nanoseconds and its interpretation depends on setting DRM_XE_UFENCE_WAIT_ABSTIME flag. Relative timeout (flag is not set) means fence expire at now() + timeout. Absolute timeout (flag is set) means that the fence expires at exact point of time. Passing negative timeout means we will wait "forever" by setting wait time to MAX_SCHEDULE_TIMEOUT.

2023-12-20kexec_file: add kexec_file flag to control debug printingBaoquan He1-0/+1
Patch series "kexec_file: print out debugging message if required", v4. Currently, specifying '-d' on kexec command will print a lot of debugging informationabout kexec/kdump loading with kexec_load interface. However, kexec_file_load prints nothing even though '-d' is specified. It's very inconvenient to debug or analyze the kexec/kdump loading when something wrong happened with kexec/kdump itself or develper want to check the kexec/kdump loading. In this patchset, a kexec_file flag is KEXEC_FILE_DEBUG added and checked in code. If it's passed in, debugging message of kexec_file code will be printed out and can be seen from console and dmesg. Otherwise, the debugging message is printed like beofre when pr_debug() is taken. Note: **** ===== 1) The code in kexec-tools utility also need be changed to support passing KEXEC_FILE_DEBUG to kernel when 'kexec -s -d' is specified. The patch link is here: ========= [PATCH] kexec_file: add kexec_file flag to support debug printing http://lists.infradead.org/pipermail/kexec/2023-November/028505.html 2) s390 also has kexec_file code, while I am not sure what debugging information is necessary. So leave it to s390 developer. Test: **** ==== Testing was done in v1 on x86_64 and arm64. For v4, tested on x86_64 again.

The debugging printing for kexec_load interface is made in user space utility kexec-tools. Whereas, with kexec_file_load interface, 'kexec -s -d' print nothing. Because kexec_file code is mostly implemented in kernel space, and the debugging printing functionality is missed. It's not convenient when debugging kexec/kdump loading and jumping with kexec_file_load interface. Now add KEXEC_FILE_DEBUG to kexec_file flag to control the debugging message printing. And add global variable kexec_file_dbg_print and macro kexec_dprintk() to facilitate the printing. This is a preparation, later kexec_dprintk() will be used to replace the existing pr_debug(). Once 'kexec -s -d' is specified, it will print out kexec/kdump loading information. If '-d' is not specified, it regresses to pr_debug().

Currently, the 'state' field in 'struct br_port_msg' can be set to 1 if the MDB entry is permanent or 0 if it is temporary. Additional states might be added in the future.

2023-12-19drm/xe: Memory allocations are tile-based, not GT-basedMatt Roper1-2/+2
Since memory and address spaces are a tile concept rather than a GT concept, we need to plumb tile-based handling through lots of memory-related code. Note that one remaining shortcoming here that will need to be addressed before media GT support can be re-enabled is that although the address space is shared between a tile's GTs, each GT caches the PTEs independently in their own TLB and thus TLB invalidation should be handled at the GT level. v2: - Fix kunit test build.

Intel Vulkan driver needs to know what is the maximum priority to fill a device info struct for applications. Right now we getting this information by creating a engine and setting priorities from min to high to know what is the maximum priority for running process but this leads to info messages to be printed to dmesg: xe 0000:03:00.0: [drm] Ioctl argument check failed at drivers/gpu/drm/xe/xe_engine.c:178: value == DRM_SCHED_PRIORITY_HIGH && !capable(CAP_SYS_NICE) It does not cause any harm but when executing a test suite like crucible it causes thousands of those messages to be printed.

Currently the user listening on a socket for devlink notifications gets always all messages for all existing instances, even if he is interested only in one of those. That may cause unnecessary overhead on setups with thousands of instances present. User is currently able to narrow down the devlink objects replies to dump commands by specifying select attributes. Allow similar approach for notifications. Introduce a new devlink NOTIFY_FILTER_SET which the user passes the select attributes.

The main changes are: 1) Fix kCFI bugs in BPF, from Peter Zijlstra. End result: all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y. 2) Introduce BPF token object, from Andrii Nakryiko. It adds an ability to delegate a subset of BPF features from privileged daemon (e.g., systemd) through special mount options for userns-bound BPF FS to a trusted unprivileged application. The design accommodates suggestions from Christian Brauner and Paul Moore. Example: $ sudo mkdir -p /sys/fs/bpf/token $ sudo mount -t bpf bpffs /sys/fs/bpf/token \ -o delegate_cmds=prog_load:MAP_CREATE \ -o delegate_progs=kprobe \ -o delegate_attachs=xdp 3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei. - Complete precision tracking support for register spills - Fix verification of possibly-zero-sized stack accesses - Fix access to uninit stack slots - Track aligned STACK_ZERO cases as imprecise spilled registers. It improves the verifier "instructions processed" metric from single digit to 50-60% for some programs. - Fix verifier retval logic 4) Support for VLAN tag in XDP hints, from Larysa Zaremba. 5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu. End result: better memory utilization and lower I$ miss for calls to BPF via BPF trampoline. 6) Fix race between BPF prog accessing inner map and parallel delete, from Hou Tao. 7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu. It allows BPF interact with IPSEC infra. The intent is to support software RSS (via XDP) for the upcoming ipsec pcpu work.

2023-12-17RDMA/bnxt_re: Share a page to expose per CQ info with userspaceSelvin Xavier1-0/+5
Gen P7 adapters needs to share a toggle bits information received in kernel driver with the user space. User space needs this info during the request notify call back to arm the CQ. User space application can get this page using the UAPI routines. Library will mmap this page and get the toggle bits to be used in the next ARM Doorbell. Uses a hash list to map the CQ structure from the CQ ID. CQ structure is retrieved from the hash list while the library calls the UAPI routine to get the toggle page mapping. Currently the full page is mapped per CQ. This can be optimized to enable multiple CQs from the same application share the same page and different offsets in the page.
