General Description
|
||||
===================
|
||||
|
||||
This document describes VMWare PVSCSI device interface specification.
|
||||
Created by Dmitry Fleytman (dmitry@daynix.com), Daynix Computing LTD.
|
||||
Based on source code of PVSCSI Linux driver from kernel 3.0.4
|
||||
|
||||
PVSCSI Device Interface Overview
|
||||
================================
|
||||
|
||||
The interface is based on memory area shared between hypervisor and VM.
|
||||
Memory area is obtained by driver as device IO memory resource of
|
||||
PVSCSI_MEM_SPACE_SIZE length.
|
||||
The shared memory consists of registers area and rings area.
|
||||
The registers area is used to raise hypervisor interrupts and issue device
|
||||
commands. The rings area is used to transfer data descriptors and SCSI
|
||||
commands from VM to hypervisor and to transfer messages produced by
|
||||
hypervisor to VM. Data itself is transferred via virtual scatter-gather DMA.
|
||||
|
||||
PVSCSI Device Registers
|
||||
=======================
|
||||
|
||||
The length of the registers area is 1 page (PVSCSI_MEM_SPACE_COMMAND_NUM_PAGES).
|
||||
The structure of the registers area is described by the PVSCSIRegOffset enum.
|
||||
There are registers to issue device command (with optional short data),
|
||||
issue device interrupt, control interrupts masking.
|
||||
|
||||
PVSCSI Device Rings
|
||||
===================
|
||||
|
||||
There are three rings in shared memory:
|
||||
|
||||
1. Request ring (struct PVSCSIRingReqDesc *req_ring)
|
||||
- ring for OS to device requests
|
||||
2. Completion ring (struct PVSCSIRingCmpDesc *cmp_ring)
|
||||
- ring for device request completions
|
||||
3. Message ring (struct PVSCSIRingMsgDesc *msg_ring)
|
||||
- ring for messages from device.
|
||||
This ring is optional and the guest might not configure it.
|
||||
There is a control area (struct PVSCSIRingsState *rings_state) used to control
|
||||
rings operation.
|
||||
|
||||
PVSCSI Device to Host Interrupts
|
||||
================================
|
||||
There are following interrupt types supported by PVSCSI device:
|
||||
1. Completion interrupts (completion ring notifications):
|
||||
PVSCSI_INTR_CMPL_0
|
||||
PVSCSI_INTR_CMPL_1
|
||||
2. Message interrupts (message ring notifications):
|
||||
PVSCSI_INTR_MSG_0
|
||||
PVSCSI_INTR_MSG_1
|
||||
|
||||
Interrupts are controlled via PVSCSI_REG_OFFSET_INTR_MASK register
|
||||
Bit set means interrupt enabled, bit cleared - disabled
|
||||
|
||||
Interrupt modes supported are legacy, MSI and MSI-X
|
||||
In case of legacy interrupts, register PVSCSI_REG_OFFSET_INTR_STATUS
|
||||
is used to check which interrupt has arrived. Interrupts are
|
||||
acknowledged when the corresponding bit is written to the interrupt
|
||||
status register.
|
||||
|
||||
PVSCSI Device Operation Sequences
|
||||
=================================
|
||||
|
||||
1. Startup sequence:
|
||||
a. Issue PVSCSI_CMD_ADAPTER_RESET command;
|
||||
aa. Windows driver reads interrupt status register here;
|
||||
b. Issue PVSCSI_CMD_SETUP_MSG_RING command with no additional data,
|
||||
check status and disable device messages if error returned;
|
||||
(Omitted if device messages disabled by driver configuration)
|
||||
c. Issue PVSCSI_CMD_SETUP_RINGS command, provide rings configuration
|
||||
as struct PVSCSICmdDescSetupRings;
|
||||
d. Issue PVSCSI_CMD_SETUP_MSG_RING command again, provide
|
||||
rings configuration as struct PVSCSICmdDescSetupMsgRing;
|
||||
e. Unmask completion and message (if device messages enabled) interrupts.
|
||||
|
||||
2. Shutdown sequences
|
||||
a. Mask interrupts;
|
||||
b. Flush request ring using PVSCSI_REG_OFFSET_KICK_NON_RW_IO;
|
||||
c. Issue PVSCSI_CMD_ADAPTER_RESET command.
|
||||
|
||||
3. Send request
|
||||
a. Fill next free request ring descriptor;
|
||||
b. Issue PVSCSI_REG_OFFSET_KICK_RW_IO for R/W operations;
|
||||
or PVSCSI_REG_OFFSET_KICK_NON_RW_IO for other operations.
|
||||
|
||||
4. Abort command
|
||||
a. Issue PVSCSI_CMD_ABORT_CMD command;
|
||||
|
||||
5. Request completion processing
|
||||
a. Upon completion interrupt arrival process completion
|
||||
and message (if enabled) rings.
