## Overview
|
||||
http://www.apache.org/licenses/LICENSE-2.0
|
||||
|
||||
This unit registers a USB class driver with the driver manager (`driver.mgr`) to claim USB Mass Storage Class interfaces (class `$08`, subclass `$06` SCSI, protocol `$50` Bulk-Only). When the USB stack enumerates a matching interface, the `load` callback is invoked. Currently the callback only logs a detection message; no I/O infrastructure is established.

|
||||
|
||||
Full Bulk-Only Transport (BOT) support — including Max LUN query, endpoint setup, CBW/CSW command exchange, and `driver.storage.mgr` device registration — is planned but not yet implemented.
|
||||
# USB mass storage
|
||||
|
||||
## Boot Registration
|
||||
`driver.storage.ctl.usb` implements SCSI transparent commands over USB Mass
|
||||
Storage Bulk-Only Transport (interface class/subclass/protocol `08/06/50`).
|
||||
|
||||
Registered with `boot.mgr` as `driver.storage.ctl.usb` at the `device` barrier. The barrier order places `device` after `bus`, ensuring `driver.bus.usb.core.init` has run before the storage class driver registers with the driver manager.
|
||||
It probes INQUIRY, TEST UNIT READY and READ CAPACITY(10), registers LUN 0 with
|
||||
the storage manager, and exposes READ(10), WRITE(10), REQUEST SENSE and
|
||||
SYNCHRONIZE CACHE(10). Existing partition discovery and filesystem mounting
|
||||
apply to the resulting USB disk. Writes complete only after cache synchronization.
|
||||
|
||||
## Dependencies
|
||||
## Execution and ownership
|
||||
|
||||
- `boot.mgr`
|
||||
An attachment task probes and registers each disk after scheduling starts; boot
|
||||
initialization never waits on a worker that cannot run yet.
|
||||
|
||||
- `driver.mgr`
|
||||
- `memory.heap`
|
||||
- `driver.storage.types`
|
||||
- `io.syslog`
|
||||
- `debug.tracer`
|
||||
- `driver.bus.usb.core`
|
||||
- `driver.bus.usb.types`
|
||||
- `core.util`, `arch.x86.util`
|
||||
Storage dispatch only publishes a request. One persistent `usb.storage` worker
|
||||
performs I/O in task context, with one command active per device and a reusable,
|
||||
page-aligned 4 KiB bounce buffer. Caller buffers are never submitted for DMA.
|
||||
Commands are split at the bounce-buffer boundary; all LBA/count and buffer-end
|
||||
arithmetic is checked before submission. CBW/CSW wire sizes, tags, status,
|
||||
residue, and actual transfer lengths are validated.
|
||||
|
||||
## Constants
|
||||
OHCI batches bulk data into spans of at most 4 KiB per transfer descriptor,
|
||||
using the endpoint's hardware toggle carry across packets. A 4 KiB full-speed
|
||||
read uses one data descriptor instead of 64. Short packets still halt the chain
|
||||
and report the actual byte count; interrupt endpoint packet sizing is unchanged.
|
||||
|
||||
| Constant | Value | Description |
|
||||
|---|---|---|
|
||||
| `USB_CLASS_MASS_STORAGE` | `$08` | USB interface class for mass storage |
|
||||
| `USB_SC_SCSI` | `$06` | SCSI transparent command set subclass |
|
||||
| `USB_PROTO_BBB` | `$50` | Bulk-Only (BOT) transport protocol |
|
||||
The worker performs reset recovery (class reset, clear bulk-IN halt, clear
|
||||
bulk-OUT halt) after malformed status or phase errors. Failed SCSI commands
|
||||
request sense and return storage errors, including write protection.
|
||||
|
||||
## Functions and Procedures
|
||||
On disconnect the disk is marked removed immediately. Accepted requests are
|
||||
completed with errors, and idle volumes are invalidated/unmounted by the worker;
|
||||
busy volumes are retried. Storage-manager records remain stable tombstones.
|
||||
Class-driver buffers and context are freed after pending hardware work drains.
|
||||
|
||||
### init
|
||||
Host controllers currently have no cancellation API. A timed-out transfer is
|
||||
therefore quarantined with its private device snapshot and DMA memory. No further
|
||||
commands are issued to that device. If hardware never completes, those allocations
|
||||
remain retained until reboot; freeing them would permit DMA into reused memory.
|
||||
The timeout uses the PIT's actual frequency and a bounded polling fallback.
|
||||
|
||||
```pascal
|
||||
procedure init;
|
||||
```
|
||||
## Supported scope
|
||||
|
||||
Constructs a `TDeviceIdentifier` matching any USB device with `bInterfaceClass = $08`, `bInterfaceSubClass = $06`, `bInterfaceProtocol = $50`, and registers the `load` callback with `driver.mgr`.
|
||||
- LUN 0 on a single-interface device with one bulk-IN and one bulk-OUT endpoint.
|
||||
- Direct-access disks with power-of-two sectors from 512 through 4096 bytes.
|
||||
- Capacity representable by the existing 32-bit storage-sector API; the
|
||||
READ CAPACITY(16) sentinel is rejected.
|
||||
- OHCI, EHCI and xHCI bulk transfers. OHCI/EHCI report actual data lengths and
|
||||
terminate bulk reads on short packets.
|
||||
|
||||
## Notes
|
||||
UAS, additional LUNs, composite/alternate-setting interfaces, UHCI storage,
|
||||
optical devices, and media replacement without USB reconnect are not supported.
|
||||
The current xHCI driver lacks endpoint-ring reset support: a halted bulk endpoint
|
||||
fails the device closed rather than attempting an unsafe ring reuse.
|
||||
|
||||
- The `load` callback currently returns true unconditionally after logging a detection message.
|
||||
- Once full BOT support is implemented, `load` should query the Max LUN, allocate endpoint structures, and call `driver.storage.mgr.register_device` for each logical unit.
|
||||
## Validation
|
||||
|
||||
`UnitTest` is called by the boot test suite and is available as `USBMSCTEST`.
|
||||
Tests use a memory-only mock host controller: wire layout, byte order, capacity
|
||||
limits, reads, writes, sense errors, short transfers, status stalls, reset ordering,
|
||||
and request bounds. They perform no disk I/O.
|
||||
|
||||
For hardware/VM checks, boot with a disposable USB disk, confirm `USBMSC` discovery
|
||||
and filesystem mounting, test file read/write/read-back, then unplug while idle
|
||||
and during I/O. Do not run destructive disk tests against a disk containing data.

|

|
||||
## Notes
|
||||
|
||||
- `dispatch_next` is an internal procedure called with interrupts disabled. It dequeues the head of the CFIFO, allocates a heap copy via `ioreq_copy` (for ISR safety), and invokes the appropriate `dispatchRead` or `dispatchWrite` on the device. If neither dispatch pointer is set, the request is failed with `eDeviceNotFound`.
|
||||
- The blocking path relies on pointer-dereferenced spin (`puint32(@wait.Done)^`) to prevent FPC from caching the `Done` flag in a register across the `hlt` instruction.
|
||||
- Devices without `dispatchRead`/`dispatchWrite` set (i.e., drivers not yet migrated to Phase 2) will have `submit_io` return `eDeviceNotFound`. Legacy drivers must be migrated before they can use the new I/O path.
|
||||
|
||||
|
||||
## Bounded performance path
|
||||
|
||||
The manager merges up to 32 consecutive queued requests when operation, device,
|
||||
LBA range, and virtual buffer range are contiguous. It never searches past the
|
||||
queue head or delays a lone request to create a merge. Drivers opt in through
|
||||
`mergeMaxSectors`; SATA AHCI advertises 65,536 sectors, while other drivers default
|
||||
to zero (disabled). A merged command delivers one completion to each original
|
||||
request, in FIFO order. A command error fails every member conservatively.
|
||||
|
||||
`storage_get_stats` takes an interrupt-protected snapshot of the device counters.
|
||||
`DISK info <index>` displays accepted/completed/failed logical requests, hardware
|
||||
commands, merged requests, queue-full rejections, queue and active high-water
|
||||
marks, successful read/write sectors, request-size buckets, queue/service ticks,
|
||||
and FAT metadata cache hits/misses. Queue ticks are accumulated per logical
|
||||
request; service ticks are accumulated per hardware command. Tick values use
|
||||
`Counters.c32`, not milliseconds. Counters are unsigned 32-bit values, start at
|
||||
device registration, and wrap; use snapshot differences over bounded benchmark
|
||||
intervals. Size buckets are <=8, 9..256, and >256 sectors.
|
||||
|
||||
FAT32 blocking and async reads share a pooled transfer engine with batches of up
|
||||
to four outstanding reads, capped by device queue depth. Destination slices are
|
||||
disjoint. On any error, the engine drains every accepted request before releasing
|
||||
its context and reports only the contiguous successful byte prefix. Unaligned
|
||||
edges and odd DMA addresses use the context's private scratch sector. Writes
|
||||
remain sequential. Run maps store cumulative file-cluster offsets; an open-file
|
||||
cursor handles sequential locality and binary search handles random seeks.
|
||||
|
||||
`STORPERF` runs memory-backed regression checks (also included in boot unit tests)
|
||||
for reverse completion order, failures, unaligned reads, run lookup, queue
|
||||
rejection, merging limits, and callback accounting. It does not access real disks
|
||||

|

## Raw read benchmark
|
||||
|
||||
`STORBENCH` is implemented and registered by `driver.storage.bench`. It performs
|
||||
read-only raw-device I/O; it does not invoke the destructive `DISKTEST` path.
|
||||
|
||||
```text

|
||||
STORBENCH compare [disk] [MiB]
|
||||
STORBENCH help
|
||||
```
|
||||
|
||||
Manual (`run`) defaults are disk 0, 128 MiB, 1024 KiB/request, sequential reads, and a depth of
|
||||
`min(4, hardware depth)` (at least one). Examples:
|
||||
|
||||
```text
|
||||
STORBENCH 0 128 64 4
|
||||
STORBENCH 0 128 4 16 random
|
||||
STORBENCH 0 256 1024 1 seq 2048
|
||||
STORBENCH compare 0 128
|
||||
```
|
||||
|
||||
The comparison runs sequential reads at 4, 64, and 1024 KiB/request, each at depths
|
||||
1, 4, 16, and 32. The MiB argument applies to each of the twelve cases. Queue depth
|
||||
may exceed hardware depth to expose software queuing and request merging.
|
||||
|
||||
Limits are 1..16384 MiB, 1..1024 KiB/request, and depth 1..32. Request size must be
|
||||
an exact number of device sectors. Buffers are allocated once per case, with a
|
||||
separate slice for every outstanding request and a maximum total size of 32 MiB.
|
||||
The transfer range is clamped to the device. Without an explicit LBA, reads start
|
||||
at sector 2048 when the full requested range fits there; otherwise they start at
|
||||
zero. Random mode uses a fixed xorshift seed and samples that range with replacement,
|
||||
so total bytes read are bounded but unique coverage is not guaranteed.
|
||||
|
||||
Reports include successful bytes, elapsed microseconds, MiB/s, IOPS, accepted and
|
||||
completed request counts, peak outstanding requests, average/p95/max completion
|
||||
latency, and per-run storage-counter deltas. Latencies are measured from submission
|
||||
to callback. The p95 is an upper bound from logarithmic microsecond buckets, not an exact
|
||||
microsecond percentile. Runs shorter than 10 ms are excluded from suite speed comparisons.
|
||||
No console output occurs inside the measured loop. Any failure stops new work;
|
||||
already accepted DMA is drained before buffers are freed, and failed requests
|
||||
contribute no bytes or successful IOPS.
|
||||
|
||||
Timing prefers the Hyper-V-compatible VM reference counter (100 ns ticks), detected
|
||||
through its Hv#1 interface and reference-counter privilege. It needs no calibration.
|
||||
Other platforms use an invariant TSC calibrated against two complete RTC seconds,
|
||||
with up to three attempts to tolerate transient RTC updates or scheduling delays.
|
||||
Calibration requires agreement within 1%; failures include the specific reason.
|
||||
Unlike delivered timer interrupts, this clock advances while interrupts are masked.
|
||||
Queue submission restores interrupts between requests. Filesystem caches are
|
||||
bypassed, but drive and virtual-machine/host caches may still affect results.
|
||||
Virtual or sparse disks can report throughput above physical-media speed.
|
||||
Device counter deltas may include concurrent I/O from other processes;
|
||||
benchmark-owned byte, request, and latency counters do not.
|
||||
|
||||
`driver.storage.bench.UnitTest` runs memory-only parser, arithmetic, range,
|
||||
queue-depth, completion-order, and error-accounting tests at boot. It never reads
|
||||
or writes a real disk. The clock tests also verify that an advertised VM reference
|
||||
counter advances with interrupts masked; they never calibrate the RTC at boot.
|
||||
|
||||
|
||||
### Automatic suite and table output
|
||||
|
||||
`STORBENCH` without arguments, or `STORBENCH auto [disk] [MiB]`, runs six
|
||||
read-only profiles. Auto defaults to disk 0 and **32 MiB per profile** (up to
|
||||
192 MiB total before device-size clamping). One or two numeric arguments select the auto suite: `STORBENCH 2 512` tests
|
||||
disk 2 with 512 MiB per profile. `STORBENCH list` lists disk indices, capacities,
|
||||
controllers, sector sizes, and hardware queue depths. Three or more numeric
|
||||
arguments retain the legacy manual syntax; `run` selects manual mode explicitly.
|
||||
|
||||
| Profile | Request size | Queue depth |
|
||||
| --- | --- | --- |
|
||||
| Seq large | 1024 KiB | 1 |
|
||||
| Seq queued | 1024 KiB | queued |
|
||||
| Seq medium | 64 KiB | queued |
|
||||
| Random small | 4 KiB | 1 |
|
||||
| Random queued | 4 KiB | queued |
|
||||
| Random medium | 64 KiB | queued |
|
||||
|
||||
Queued depth is the device hardware depth clamped to 4..16, allowing software
|
||||
queue testing even on serial devices. A request smaller than a device sector is
|
||||
increased to one sector. Each profile samples the same byte-span size, with the
|
||||
existing fixed random seed and range clamping rules.
|
||||
|
||||
Auto and compare modes print an aligned ASCII table with request KiB, queue
|
||||
depth, MiB/s, IOPS, average latency, p95 latency upper bound, and status. Rows are
|
||||
printed outside the measured loop. Successful runs shorter than 10 ms show `-` metrics and
|
||||
`SHORT`, and are excluded from best-result and queue-gain summaries. Errors show
|
||||
`FAILED`, stop the suite after accepted DMA has drained, and leave remaining
|
||||
profiles unrun. The summary includes successful profiles, bytes actually read,
|
||||
measured time, best sequential throughput, peak random IOPS, and (in auto mode)
|
||||
queued/QD1 throughput ratios. These ratios describe the measured cases, including
|
||||
any controller-cache effects; they are not a hardware rating.

```
|
||||
|
||||
Profiles reuse the same raw device range. Host/drive caches are not flushed, so
|
||||
later profiles may read warm data. These results are observed raw read throughput,
|
||||
not a claim of uncached physical-media performance.

The `restore_if` helper checks bit 9 (IF) of the saved EFLAGS word and issues `STI` only if interrupts were enabled on entry. It uses `STI` rather than `POPFD` to avoid restoring potentially dangerous EFLAGS bits (IOPL, NT, VM, AC) that could trigger a General Protection Fault or Bad-TSS on the next `IRET`.

When `DEBUG_LMM` is defined, `kalloc` allocates one additional unit and writes `GUARD_MAGIC` at the end of the allocation. `kfree` verifies this sentinel before freeing; a mismatch triggers a GPF with a syslog error, catching buffer overruns at free time.
