From a978f3c3d182b14b7fedf0b2654e7a0a45c1e016 Mon Sep 17 00:00:00 2001 From: Ryan Breen Date: Mon, 23 Feb 2026 05:10:34 -0500 Subject: [PATCH 1/6] feat: EP0 mouse polling, bandwidth dance, CC=12 investigation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Systematic investigation of CC=12 (Endpoint Not Enabled) on Parallels ARM64 virtual xHCI interrupt endpoints, with working EP0 GET_REPORT polling for both keyboard and mouse. ## Findings CC=12 on interrupt IN is a fundamental Parallels virtual xHC limitation: - Parallels proactively generates CC=12 Transfer Events after re-ConfigureEndpoint (before any TRBs are queued), signaling that interrupt IN transfers are not supported - This persists regardless of command sequence: BSR=0/1, bandwidth dance enabled/disabled, BEI flag, matching Linux byte-for-byte - EP0 control transfers work reliably; interrupt IN never completes - Linux keyboard/mouse works via Parallels Tools injection, not xHCI interrupt IN (Linux ftrace shows no interrupt TRB completions in trace) ## Working solution: EP0 GET_REPORT polling Both keyboard and mouse input work via EP0 GET_REPORT control transfers at 4 Hz (limited by Parallels virtual USB device timing, not our polling interval): - gr=N gk=N mr=N mk=N with ge=me=0 (zero errors) verified in testing - Ring recycling (StopEndpoint + SetTRDequeuePointer) for EP0 rings since Parallels does not follow Link TRBs on transfer rings ## Changes xhci.rs: - Mouse EP0 GET_REPORT polling: SET_PROTOCOL(boot) during init, then 4 Hz boot-protocol GET_REPORT via EP0 with ring recycling - EP0 ring recycling for keyboard (every ~84 polls) and mouse - Bandwidth dance (SKIP_BW_DANCE=false): matches Linux's xhci_check_bandwidth() sequence with 3x ConfigureEndpoint + 2x StopRing per slot — confirmed matching Linux ftrace byte-for-byte - BSR=0 confirmed correct (BSR=1 causes CC=19 Context State Error) - Added EP0_MOUSE_POLL_STATE, MOUSE_CTRL_DATA_BUF, queue_ep0_mouse_get_report() - Diagnostics: DIAG_DOORBELL_EP_STATE, DMA buffer address logging, endpoint state read after SET_CONFIG and at doorbell time - Polling interval: % 10 (20 Hz attempt; bottleneck is Parallels ~4 Hz) timer_interrupt.rs: - Heartbeat counters: mr= mk= me= for mouse EP0 polling status Co-Authored-By: Ryan Breen Co-Authored-By: Claude Opus 4.6 --- .../src/arch_impl/aarch64/timer_interrupt.rs | 6 + kernel/src/drivers/usb/descriptors.rs | 2 + kernel/src/drivers/usb/xhci.rs | 991 ++++++++++++++---- 3 files changed, 785 insertions(+), 214 deletions(-) diff --git a/kernel/src/arch_impl/aarch64/timer_interrupt.rs b/kernel/src/arch_impl/aarch64/timer_interrupt.rs index dd1902c7..854a90ea 100644 --- a/kernel/src/arch_impl/aarch64/timer_interrupt.rs +++ b/kernel/src/arch_impl/aarch64/timer_interrupt.rs @@ -292,6 +292,12 @@ pub extern "C" fn timer_interrupt_handler() { print_timer_count_decimal(crate::drivers::usb::xhci::EP0_GET_REPORT_OK.load(Ordering::Relaxed));

Three changes bring the reset rate from 200/s down to ~10/s: 1. wait_for_command_completion CC=12 path: route to MSI_*_NEEDS_REQUEUE instead of NEEDS_RESET_*. This breaks the cascade where one endpoint's reset command wait sets NEEDS_RESET_* for the other endpoint's CC=12 event, causing both endpoints to reset on the same poll tick. 2. RESET_INTERVAL_TICKS (20 ticks = 100ms at 200Hz) + per-endpoint last-reset poll counters. NEEDS_RESET_* is deferred until the minimum interval elapses, capping resets at 10/s per endpoint. 3. CC=12 in handle_interrupt and poll_hid_events routes to NEEDS_RESET_* (not MSI_*_NEEDS_REQUEUE) so Halted endpoints get proper Reset Endpoint recovery rather than a doorbell that Halted endpoints silently ignore.

All diagnostics now go through the lock-free xhci_trace ring buffer (no locks, no allocations, safe in interrupt context). Only xhci_trace_dump() retains serial output for post-init trace extraction. Key changes: - xhci.rs: Remove all serial_println, replace key milestones with xhci_trace_note() calls. Fix Mult field to 0 per xHCI spec §6.2.3 (was incorrectly 1 for interrupt endpoints). Add USBLEGSUP handoff in Extended Capabilities parsing. Revert No-Op TRB diagnostic back to Normal TRB. - timer_interrupt.rs: Trim heartbeat to essential fields only (time, ctx switches, syscalls, xhci errors, kbd events, first CC). - pci.rs: Add enable_intx() and disable_msi() methods. - drivers/mod.rs: Remove raw_serial_str debug breadcrumbs. - build.rs: Add build ID based on timestamp for stale-build detection. - main_aarch64.rs: Print BUILD_ID in boot banner. - build-efi.sh: Prefer mformat over newfs_msdos for FAT32 on macOS. - deploy-to-vm.sh: Rewrite with prl_disk_tool HDD creation, serial log truncation, NVRAM cleanup, and --boot flag. - CLAUDE.md: Document Parallels VM workflow and restart protocol. - Add Linux xHCI ftrace reference and trace analysis scripts. CC=12 (ENDPOINT_NOT_ENABLED) on interrupt IN endpoints remains unsolved.

The Linux trace shows: +- Line 729-731: ConfigureEndpoint with add_flags "slot 1in 2in" (0x29) +- Line 863-866: First interrupt IN TRB queued for slot 2 +- Linux does NOT ring doorbells for mouse interrupt endpoints in the trace window + +**Key question:** Does Linux queue interrupt TRBs BEFORE or AFTER SET_CONFIGURATION? Our code queues AFTER, which matches the trace, but the timing/ordering within the post-config phase may matter. + +### Theory 2: Parallels vxHC Requires Specific Port/Slot Binding +The virtual xHC may enforce that interrupt endpoints only work on USB 2.0 ports (13-14), not USB 3.0 ports (1-12). Linux might be using different port assignments. Check the Linux trace carefully for which ports devices enumerate on. + +### Theory 3: Missing Scratchpad/Context Memory Requirements +Even though the xHC reports 0 scratchpad buffers, Parallels might need something additional in the DCBAA or device context area. + +### Theory 4: Cache Coherency Issue (ARM64-specific) +We do `dc cvac` (clean) on TRBs and contexts before commands, and `dc civac` (clean+invalidate) on buffers before reading. But the sequence or scope might be wrong. The xHC might be reading stale data from a cache line we didn't clean. + +### Theory 5: Ring Segment / Alignment +Transfer rings are 4KB-aligned (page allocation). But the xHCI spec may require additional alignment for the Parallels vxHC, or the ring physical address may be computed incorrectly in edge cases. + +### Theory 6: Output Context Not Being Used Correctly +After Address Device succeeds, the Output Context has the device's actual endpoint state. Our configure_endpoints_batch reads the Slot Context from Output Context correctly, but the endpoint contexts in the Input Context are built from scratch (our descriptor parsing), not modified from the Output Context.

The xhci_trace captures every MMIO write. Compare against the Linux ftrace. The CC=12 answer MUST be in a difference we haven't found yet. + +2. **Check if Linux uses USB 2.0 ports** for these HID devices. Our code enumerates on USB 3.0 ports (1-12). If Parallels routes HID devices to USB 2.0 ports (13-14), our port assignment would be wrong. + +3. **Investigate the xHC's Internal State** — after ConfigureEndpoint succeeds (CC=1) and endpoints show Running, something happens between that point and the first doorbell that causes the xHC to consider the endpoint "not enabled." This could be a Parallels vxHC quirk where it requires a specific event or delay. + +4. **Try the exact Linux sequence** — replicate Linux's init flow exactly as shown in the ftrace, including any MMIO writes we might be skipping (like operational register reads, PORTSC writes, etc.). + +5. **Compare Output Context** after our ConfigureEndpoint vs Linux's. The xHC writes back its understanding of the endpoint configuration into the Output Context. If the output differs between our driver and Linux's, that reveals what the xHC is rejecting. + +--- + +## Previous Commit History + +``` +d72c8c7 fix: xHCI CC=12 reset storm — rate limiting + cascade prevention +eb595bd feat: mouse2 interrupt EP support, remove EP0 polling workaround, CC=12 diagnostics +a978f3c feat: EP0 mouse polling, bandwidth dance, CC=12 investigation +b1899ea feat: xHCI endpoint context matching Linux, EP0 GET_REPORT polling, MSI hardening +f3f4f90 feat: EHCI driver, xHCI bulk-for-interrupt workaround, class request diagnostics +6971f9e fix: correct xHCI endpoint context layout per spec, fix transfer ring index collision +2464de4 fix: increase Parallels display to 2560x1600, document hybrid GPU+GOP architecture +d605cd7 feat: VirtIO GPU PCI + XHCI USB drivers for Parallels ARM64 display +``` From 543304bb6d95ab157db5d04b7919405bbf83ad87 Mon Sep 17 00:00:00 2001 From: Ryan Breen Date: Fri, 27 Feb 2026 06:35:25 -0500 Subject: [PATCH 6/6] feat: ARM64 tracing init, fork+exit instrumentation, clean timer interrupt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Enable tracing on ARM64: init(), providers::init(), enable(), enable_all() in main_aarch64.rs — tracing was completely dead on ARM64 before this - Remove ~60 lines of serial I/O from timer interrupt heartbeat block, replace with single lock-free trace event (~5 instructions) - Add fork+exit trace probes: SPAWN_FRONT, WAITPID_BLOCK, WAITPID_WAKE, THREAD_EXIT in process provider for hang diagnosis - Add SCHED_QUEUE_STATE probe to scheduler provider - Add HEARTBEAT_MARKER probe to IRQ provider - Instrument fork/waitpid/exit/context-switch code paths with trace calls - Add ready_queue_length() to Scheduler for tracing - Add boot-cycle-test.sh for automated Parallels boot testing - Verified 10/10 consecutive boot cycles pass fork+exit tests (0 hangs) - xHCI CC=12 investigation: lock-free tracing, linux reference driver Co-Authored-By: Ryan Breen Co-Authored-By: Claude Opus 4.6 --- kernel/Cargo.toml | 3 +- kernel/build.rs | 56 +- .../src/arch_impl/aarch64/context_switch.rs | 6 +- kernel/src/arch_impl/aarch64/syscall_entry.rs | 4 + .../src/arch_impl/aarch64/timer_interrupt.rs | 34 +- kernel/src/drivers/mod.rs | 24 +- kernel/src/drivers/pci.rs | 2 +- .../src/drivers/usb/linux_xhci/linux_xhci.c | 1689 +++++++++++++++++ .../src/drivers/usb/linux_xhci/linux_xhci.h | 20 + kernel/src/drivers/usb/mod.rs | 2 + kernel/src/drivers/usb/xhci.rs | 1162 +++++++++--- kernel/src/drivers/usb/xhci_linux.rs | 107 ++ kernel/src/main_aarch64.rs | 7 + kernel/src/syscall/handlers.rs | 4 + kernel/src/syscall/wait.rs | 8 + kernel/src/task/process_task.rs | 4 + kernel/src/task/scheduler.rs | 5 + kernel/src/tracing/core.rs | 8 +- kernel/src/tracing/providers/irq.rs | 24 + kernel/src/tracing/providers/process.rs | 88 + kernel/src/tracing/providers/sched.rs | 26 + scripts/parallels/boot-cycle-test.sh | 70 + scripts/parallels/build-efi.sh | 7 +- scripts/parse-xhci-trace.py | 1 + 24 files changed, 3053 insertions(+), 308 deletions(-) create mode 100644 kernel/src/drivers/usb/linux_xhci/linux_xhci.c create mode 100644 kernel/src/drivers/usb/linux_xhci/linux_xhci.h create mode 100644 kernel/src/drivers/usb/xhci_linux.rs create mode 100755 scripts/parallels/boot-cycle-test.sh diff --git a/kernel/Cargo.toml b/kernel/Cargo.toml index a9f31e45..d2deea4e 100644 --- a/kernel/Cargo.toml +++ b/kernel/Cargo.toml @@ -4,7 +4,7 @@ version = "0.1.0" edition = "2021" [lints.rust] -unexpected_cfgs = { level = "warn", check-cfg = ["cfg(never)", "cfg(feature, values(\"particle_animation\"))"] } +unexpected_cfgs = { level = "warn", check-cfg = ["cfg(never)", "cfg(feature, values(\"particle_animation\", \"xhci_linux_harness\"))"] } [[bin]] name = "kernel" @@ -28,6 +28,7 @@ testing = [] boot_tests = [] # Parallel boot test framework btrt = [] # Boot Test Result Table (structured test results) kthread_test_only = ["testing"] # Run only kthread tests and exit +xhci_linux_harness = [] # Build and use the Linux C-based xHCI harness kthread_stress_test = ["testing"] # Run kthread stress test (100+ kthreads) and exit workqueue_test_only = ["testing"] # Run only workqueue tests and exit dns_test_only = ["testing", "external_test_bins"] # Run only DNS test and exit (fast network debugging) diff --git a/kernel/build.rs b/kernel/build.rs index 9d74a4f8..9ed81323 100644 --- a/kernel/build.rs +++ b/kernel/build.rs @@ -11,10 +11,6 @@ fn main() { .unwrap_or_default(); let build_id = format!("{:010x}{:04x}", ts.as_secs(), (ts.subsec_nanos() >> 16) & 0xFFFF); println!("cargo:rustc-env=BREENIX_BUILD_ID={}", build_id); - // Print to build output so agents and humans can capture the ID without - // extracting it from the binary.
