Introduction:
|
||||
=============
|
||||
|
||||
The Qualcomm crypto engine (qce) driver is a module that
|
||||
provides common services for accessing the Qualcomm crypto device.
|
||||
Currently, the two main clients of qce are
|
||||
-qcrypto driver (module provided for accessing CE HW by kernel space apps)
|
||||
-qcedev driver (module provided for accessing CE HW by user space apps)
|
||||
|
||||
|
||||
The crypto engine (qce) driver is a client to the DMA driver for the Qualcomm
|
||||
DMA device - Application Data Mover (ADM). ADM is used to provide the DMA
|
||||
transfer capability between Qualcomm crypto device hardware and DDR memory
|
||||
for crypto operations.

The entities marked with (*) in the Figure 1, are the software components of

the Linux Qualcomm crypto modules.
|

|
||||
===============
|
||||
IMPORTANT NOTE:
|
||||
===============
|
||||
(1) The CE hardware can be accessed either from user space OR kernel space,
|
||||
at one time. Both user space and kernel space clients cannot access the
|
||||
qce driver (and the CE hardware) at the same time.
|
||||
- If your device has user space apps that needs to access the crypto
|
||||
hardware, make sure to have the qcrypto module disabled/unloaded.
|
||||
This will result in the kernel space apps to use the registered
|
||||
software implementation of the crypto algorithms.
|
||||
- If your device has kernel space apps that needs to access the
|
||||
crypto hardware, make sure to have qcedev module disabled/unloaded
|
||||
and implement your user space application to use the software
|
||||
implemenation (ex: openssl/crypto) of the crypto algorithms.
|
||||
|
||||
(2) If your device has Playready(Windows Media DRM) application enabled and
|
||||
uses the qcedev module to access the crypto hardware accelarator,
|
||||
please be informed that for performance reasons, the CE hardware will need
|
||||
to be dedicated to playready application. Any other user space application
|
||||
should be implemented to use the software implemenation (ex: openssl/crypto)
|
||||
of the crypto algorithms.

Hardware description:
|
||||
=====================
|
||||
|
||||
Qualcomm Crypto HW device family provides a series of algorithms implemented
|
||||
in the device hardware.
|
||||
|
||||
Crypto 2 hardware provides hashing - SHA-1, SHA-256, ciphering - DES, 3DES, AES
|
||||
algorithms, and concurrent operations of hashing, and ciphering.
|
||||
|
||||
In addition to those functions provided by Crypto 2 HW, Crypto 3 HW provides
|
||||
fast AES algorithms.
|
||||
|
||||
In addition to those functions provided by Crypto 3 HW, Crypto 3E provides
|
||||
HMAC-SHA1 hashing algorithm, and Over The Air (OTA) f8/f9 algorithms as
|
||||
defined by the 3GPP forum.
|
||||
|
||||
|
||||
Software description
|
||||
====================
|
||||
|
||||
The crypto device is defined as a platform device. The driver is
|
||||
independent of the platform. The driver supports multiple instances of
|
||||
crypto HW.
|
||||
All the platform specific parameters are defined in the board init
|
||||
file, eg. arch/arm/mach-msm/board-msm7x30.c for MSM7x30.
|
||||
|
||||
The qce driver provide the common services of HW crypto
|
||||
access to the two drivers as listed above (qcedev, qcrypto. It sets up
|
||||
the crypto HW device for the operation, then it requests ADM driver for
|
||||
the DMA of the crypto operation.
|
||||
|
||||
Two ADM channels and two command lists (one command list for each
|
||||
channel) are involved in an operation.
|
||||
|
||||
The setting up of the command lists and the procedure of the operation
|
||||
of the crypto device are described in the following sections.
|
||||
|
||||
The command list for the first DMA channel is set up as follows:
|
||||
|
||||
1st command of the list is for the DMA transfer from DDR memory to the
|
||||
crypto device to input data to crypto device. The dst crci of the command
|
||||
is set for crci-in for this crypto device.
|
||||
|
||||
2nd command is for the DMA tansfer is from crypto device to DDR memory for
|
||||
the authentication result. The src crci is set as crci-hash-done of the
|
||||
crypto device. If authentication is not required in the operation,
|
||||
the 2nd command is not used.
|
||||
|
||||
The command list for the second DMA channel is set up as follows:
|
||||
|
||||
One command to DMA data from crypto device to DDR memory for encryption or
|
||||
decryption output from crypto device.
|
||||
|
||||
To accomplish ciphering and authentication concurrent operations, the driver
|
||||
performs the following steps:
|
||||
(a). set up HW crypto device
|
||||
(b). hit the crypto go register.
|
||||
(c). issue the DMA command of first channel to the ADM driver,
|
||||
(d). issue the DMA command of 2nd channel to the ADM driver.
|
||||
|
||||
SHA1/SHA256 is an authentication/integrity hash algorithm. To accomplish
|
||||
hash operation (or any authentication only algorithm), 2nd DMA channel is
|
||||
not required. Only steps (a) to (c) are performed.
|
||||
|
||||
At the completion of the DMA operation (for (c) and (d)) ADM driver
|
||||
invokes the callback registered to the DMA driver. This signifies the end of
|
||||
the DMA operation(s). The driver reads the status and other information from
|
||||
the CE hardware register and then invokes the callback to the qce driver client.
|
||||
This signal the completion and the results of the DMA along with the status of
|
||||
the CE hardware to the qce driver client. This completes a crypto operation.
|
||||
|
||||
In the qce driver initialization, memory for the two command lists, descriptor
|
||||
lists for each crypto device are allocated out of coherent memory, using Linux
|
||||
DMA API. The driver pre-configures most of the two ADM command lists
|
||||
in the initialization. During each crypto operation, minimal set up is required.
|
||||
src_dscr or/and dst_dscr descriptor list of the ADM command are populated
|
||||
from the information obtained from the corresponding data structure. eg: for
|
||||
AEAD request, the following data structure provides the information:
|
||||
|
||||
struct aead_request *req
|
||||
......
|
||||
req->assoc
|
||||
req->src
|
||||
req->dst
|
||||
|
||||
The DMA address of a scatter list will be retrieved and set up in the
|
||||
descriptor list of an ADM command.

||||

Interface:
|
||||
==========
|
||||
|
||||
The interface is defined in kernel/drivers/crypto/msm/inc/qce.h
|
||||
|
||||
The clients qcrypto, qcedev drivers are the clients using
|
||||
the interfaces.
|
||||
|
||||
The following services are provided by the qce driver -
|
||||
|
||||
qce_open(), qce_close(), qce_ablk_cipher_req(),
|
||||
qce_hw_support(), qce_process_sha_req()
|
||||
|
||||
qce_open() is the first request from the client, ex. Qualcomm crypto
|
||||
driver (qcedev, qcrypto), to open a crypto engine. It is normally
|
||||
called at the probe function of the client for a device. During the
|
||||
probe,
|
||||
- ADM command list structure will be set up
|
||||
- Crypto device will be initialized.
|
||||
- Resource associated with the crypto engine is retrieved by doing
|
||||
platform_get_resource() or platform_get_resource_byname().
|
||||
|
||||
The resources for a device are
|
||||
- crci-in, crci-out, crci-hash-done
|
||||
- two DMA channel IDs, one for encryption and decryption input, one for
|
||||
output.
|
||||
- base address of the HW crypto device.
|
||||
|
||||
qce_close() is the last request from the client. Normally, it is
|
||||
called from the remove function of the client.
|
||||
|
||||
qce_hw_support() allows the client to query what is supported
|
||||
by the crypto engine hardware.
|
||||
|
||||
qce_ablk_cipher_req() provides ciphering service to the client.
|
||||
qce_process_sha_req() provide hashing service to the client.
|
||||
qce_aead_req() provide aead service to the client.
|
||||
|
||||
Module parameters:
|
||||
==================
|
||||
|
||||
The following module parameters are defined in the board init file.
|
||||
-CE hardware nase register address
|
||||
-Data mover channel used for transfer to/from CE hardware
|
||||
These parameters differ in each platform.
|
||||
|
||||
|
||||
Dependencies:
|
||||
=============
|
||||
|
||||
Existing DMA driver.
|
||||
The transfers are DMA'ed between the crypto hardware and DDR memory via the
|
||||
data mover, ADM. The data transfers are set up to use the existing dma driver.

|

The setting up of the command lists and the procedure of the operation

|
||||
|
||||
The command lists contains a single command. For the first DMA channel it
|
||||
is set up as follows:
|
||||
|
||||
The command is for the DMA transfer from DDR memory to the
|
||||
crypto device to input data to crypto device. The dst crci of the command
|

is set for crci-in for this crypto device.
|

the CE hardware register. For HASH functions (SHA1/SHA256, HMAC, CMAC and
|
||||
CCM) were the MAC/HASH information is read off hardware registers.
|
||||
|
||||
[ NOTE: This is different from what is done in the qce module that support
|
||||
CE3.x hardware. In CE4.0 there is not CRCI_HASH and hence we cannot rely
|
||||
on the data mover to populate the HMAC/SHA information. This information
|
||||
is acquired fromte h ahrdware by reading directly from some registers that
|
||||
hold this information ]
|
||||
|
||||
The driver than nvokes the callback to the qce driver client.
|
||||
This signal the completion and the results of the DMA along with the status of
|
||||
the CE hardware to the qce40 driver client. This completes a crypto operation.
|
||||
|
||||
In the qce40 driver initialization, memory for the two command lists, descriptor
|
||||
lists for each crypto device are allocated out of coherent memory, using Linux
|

DMA API. The driver pre-configures most of the two ADM command lists

......
|

req->assoc
|
||||
req->src
|

Hardware description:
|
||||
=====================
|

Crypto 3E provides cipher and hash algorithms as defined in the
|
||||
3GPP forum specifications.

|
||||
|
||||
Software description
|
||||
====================
|
||||
|
||||
The driver is a Linux platform device driver. For an msm target,
|
||||
there can be multiple crypto devices assigned for QCEDEV.
|
||||
|
||||
The driver is a misc device driver as well.
|
||||
The following operations are registered in the driver,
|
||||
-qcedev_ioctl()
|
||||
-qcedev_open()
|
||||
-qcedev_release()
|
||||
|
||||
The following IOCTLS are available to the user space application(s)-
|
||||
|
||||
Cipher IOCTLs:
|
||||
--------------
|
||||
QCEDEV_IOCTL_ENC_REQ is for encrypting data.
|
||||
QCEDEV_IOCTL_DEC_REQ is for decrypting data.
|
||||
|
||||
Hashing/HMAC IOCTLs
|
||||
-------------------
|
||||
|
||||
QCEDEV_IOCTL_SHA_INIT_REQ is for initializing a hash/hmac request.
|
||||
QCEDEV_IOCTL_SHA_UPDATE_REQ is for updating hash/hmac.
|
||||
QCEDEV_IOCTL_SHA_FINAL_REQ is for ending the hash/mac request.
|
||||
QCEDEV_IOCTL_GET_SHA_REQ is for retrieving the hash/hmac for data
|
||||
packet of known size.
|
||||
QCEDEV_IOCTL_GET_CMAC_REQ is for retrieving the MAC (using AES CMAC
|
||||
algorithm) for data packet of known size.
|
||||
|
||||
The requests are synchronous. The driver will put the process to
|
||||
sleep, waiting for the completion of the requests using wait_for_completion().
|
||||
|
||||
Since the requests are coming out of user space application, before giving
|
||||
the requests to the low level qce driver, the ioctl requests and the
|
||||
associated input/output buffer will have to be safe checked, and copied
|
||||
to/from kernel space.
|
||||
|
||||
The extra copying of requests/buffer can affect the performance. The issue
|
||||
with copying the data buffer is resolved by having the client use PMEM
|
||||
allocated buffers.
|
||||
|
||||
NOTE: Using memory allocated via PMEM is supported only for in place
|
||||
operations where source and destination buffers point to the same
|
||||
location. Support for different source and destination buffers
|
||||
is not supported currently.
|
||||
Furthermore, when using PMEM, and in AES CTR mode, when issuing an
|
||||
encryption or decryption request, a non-zero byteoffset is not
|
||||
supported.
|
||||
|
||||
The design of the driver is to allow multiple open, and multiple requests
|
||||
to be issued from application(s). Therefore, the driver will internally queue
|
||||
the requests, and serialize the requests to the low level qce (or qce40) driver.
|
||||
|
||||
On an IOCTL request from an application, if there is no outstanding
|
||||
request, a the driver will issue a "qce" request, otherwise,
|
||||
the request is queued in the driver queue. The process is suspended
|
||||
waiting for completion.
|
||||
|
||||
On completion of a request by the low level qce driver, the internal
|
||||
tasklet (done_tasklet) is scheduled. The sole purpose of done_tasklet is
|
||||
to call the completion of the current active request (complete()), and
|
||||
issue more requests to the qce, if any.
|
||||
When the process wakes up from wait_for_completion(), it will collect the
|
||||
return code, and return the ioctl.
|
||||
|
||||
A spin lock is used to protect the critical section of internal queue to
|
||||
be accessed from multiple tasks, SMP, and completion callback
|
||||
from qce.
|
||||
|
||||
The driver maintains a set of statistics using debug fs. The files are
|
||||
in /debug/qcedev/stats1, /debug/qcedev/stats2, /debug/qcedev/stats3;
|
||||
one for each instance of device. Reading the file associated with
|
||||
a device will retrieve the driver statistics for that device.
|
||||
Any write to the file will clear the statistics.

||||

n/a
|
||||
|
||||
|
||||
Interface:
|
||||
==========
|
||||
|
||||
Linux user space applications will need to open a handle
|
||||
(file desrciptor) to the qcedev device. This is achieved by doing
|
||||
the following to retrieve a file desrciptor to the device.
|
||||
|
||||
fd = open("/dev/qce", O_RDWR);
|
||||
..
|
||||
ioctl(fd, ...);
|
||||
|
||||
Once a valid fd is retrieved, user can call the following ioctls with
|
||||
the fd as the first parameter and a pointer to an appropriate data
|
||||
structure, qcedev_cipher_op_req or qcedev_sha_op_req (depending on
|
||||
cipher/hash functionality) as the second parameter.
|
||||
|
||||
The following IOCTLS are available to the user space application(s)-
|
||||
|
||||
Cipher IOCTLs:
|

--------------
|
||||
QCEDEV_IOCTL_ENC_REQ is for encrypting data.
|
||||
QCEDEV_IOCTL_DEC_REQ is for decrypting data.
|
||||
|

The caller of the IOCTL passes a pointer to the structure shown
|
||||
below, as the second parameter.

Module parameters:
|
||||
==================
|
||||
|
||||
The following module parameters are defined in the board init file.
|
||||
-CE hardware nase register address
|
||||
-Data mover channel used for transfer to/from CE hardware
|
||||
These parameters differ in each platform.
|
||||
|
||||
|
||||
|
||||
Dependencies:
|
||||
=============
|
||||
qce driver. Please see Documentation/arm/msm/qce.txt.
|
||||
|
||||
|
||||
User space utilities:
|
||||
=====================
|
||||
|
||||
none
|
||||
|
||||
Known issues:
|
||||
=============
|
||||
|
||||
none.
|
||||
|
||||
|
||||
To do:
|
||||
======
|
||||
Enhance Cipher functionality:
|
||||
(1) Add support for handling > 32KB for ciphering functionality when
|
||||
- operation is not an "in place" operation (source != destination).
|
||||
(when using PMEM allocated memory)
|
||||
|
||||
Limitations:
|
||||
============
|
||||
(1) In case of cipher functionality, Driver does not support
|
||||
a combination of different memory sources for source/destination.
|
||||
In other words, memory pointed to by src and dst,
|
||||
must BOTH (src/dst) be "pmem" or BOTH(src/dst) be "vbuf".
|
||||
|
||||
(2) In case of hash functionality, driver does not support handling data
|
||||
buffers allocated via PMEM.
|
||||
|
||||
(3) Do not load this driver if your device already has kernel space apps
|
||||
that need to access the crypto hardware.
|
||||
Make sure to have qcedev module disabled/unloaded and implement your user
|
||||
space application to use the software implemenation (ex: openssl/crypto)
|
||||
of the crypto algorithms.
|
||||
(NOTE: Please refer to details on the limitations listed in qce.txt)
|
||||
|
||||
(4) If your device has Playready (Windows Media DRM) application enabled
|
||||
and uses the qcedev module to access the crypto hardware accelarator,
|
||||
please be informed that for performance reasons, the CE hardware will
|
||||
need to be dedicated to playready application. Any other user space
|
||||
application should be implemented to use the software implemenation
|
||||
(ex: openssl/crypto) of the crypto algorithms.

Introduction:
|
||||
=============
|
||||
|
||||
Qualcomm Crypto (qcrypto) driver is a Linux crypto driver which interfaces
|
||||
with the Linux kernel crypto API layer to provide the HW crypto functions.
|
||||
This driver is accessed by kernel space apps via the kernel crypto API layer.
|
||||
At present there is no means for user space apps to access this module.
|
||||
|
||||
Hardware description:
|
||||
=====================
|
||||
|
||||
Qualcomm Crypto HW device family provides a series of algorithms implemented
|
||||
in the device.
|
||||
|
||||
Crypto 2 hardware provides hashing - SHA-1, SHA-256, ciphering - DES, 3DES, AES
|
||||
algorithms, and concurrent operations of hashing, and ciphering.
|
||||
|
||||
In addition to those functions provided by Crypto 2 HW, Crypto 3 provides fast
|
||||
AES algorithms.
|
||||
|
||||
In addition to those functions provided by Crypto 3 HW, Crypto 3E provides
|
||||
HMAC-SHA1 hashing algorithm.
|
||||
|
||||
In addition to those functions provided by Crypto 3 HW, Crypto 4.0 provides
|
||||
HMAC-SHA1/SHA256, AES CBC-MAC hashing algorithm and AES XTS/CCM cipher
|
||||
algorithms.
|
||||
|
||||
|
||||
Software description
|
||||
====================
|
||||
|
||||
The module init function (_qcrypto_init()), does a platform_register(),
|
||||
to register the driver. As the result, the driver probe function,
|
||||
_qcrypto_probe(), will be invoked for each registered device.
|
||||
|
||||
In the probe function, driver opens the low level CE (qce_open), and
|
||||
registers the supported algorithms to the kernel crypto API layer.
|
||||
Currently, qcrypto supports the following algorithms.
|
||||
|
||||
ablkcipher -
|
||||
cbc(aes),ecb(aes),ctr(aes)
|
||||
ahash -
|
||||
sha1, sha256
|
||||
aead -
|
||||
authenc(hmac(sha1),cbc(aes))
|
||||
|
||||
The hmac(sha1), hmac(sha256, authenc(hmac(sha1),cbc(aes)), ccm(aes)
|
||||
and xts(aes) algorithms are registered for some platforms that
|
||||
support these in the CE hardware
|
||||
|
||||
The HW device can support various algorithms. However, the most important
|
||||
algorithms to gain the performance using a HW crypto accelerator are
|
||||
AEAD, and ABLKCIPHER.
|
||||
|
||||
AEAD stands for "authentication encryption with association data".
|
||||
ABLKCIPHER stands of "asynchronous block cipher".
|
||||
|
||||
The AEAD structure is described in the following header file
|
||||
LINUX/opensource/kernel/include/crypto/aead.h
|
||||
|
||||
The design of the driver is to allow multiple requests
|
||||
issued from kernel client SW (eg IPSec).
|
||||
Therefore, the driver will have to internally queue the requests, and
|
||||
serialize the requests to the low level qce driver.
|
||||
|
||||
When a request is received from the client, if there is no outstanding
|
||||
request, a qce (or qce40) request is issued, otherwise, the request is
|
||||
queued in the driver queue.
|
||||
|
||||
On completion of a request, the qce (or qce40) invokes the registered
|
||||
callback from the qcrypto. The internal tasklet (done_tasklet) is scheduled
|
||||
in this callback function. The sole purpose of done_tasklet is
|
||||
to call the completion of the current active request, and
|
||||
issue more requests to the qce (or qce40), if any exists.
|
||||
|
||||
A spin lock is used to protect the critical section of internal queue to
|
||||
be accessed from multiple tasks, SMP, and completion callback
|
||||
from qce.
|
||||
|
||||
The driver maintains a set of statistics using debug fs. The files are
|
||||
in /debug/qcrypto/stats1, /debug/qcrypto/stats2, /debug/qcrypto/stats3;
|
||||
one for each instance of device. Reading the file associated with
|
||||
a device will retrieve the driver statistics for that device.
|
||||
Any write to the file will clear the statistics.
|
||||
|
||||
Test vectors for authenc(hmac(sha1),cbc(aes)) algorithm are
|
||||
developed offline, and imported to crypto/testmgr.c, and crypto/testmgr.h.

Add Hashing algorithms.
|
||||
|

|
||||
Limitations:
|
||||
===============
|
||||
(1) Each packet transfer size (for cipher and hash) is limited to maximum of
|
||||
32KB. This is a limitation in the crypto engine hardware. Client will
|
||||
have to break packets larger than 32KB into multiple requests of smaller
|
||||
size data packets.
|
||||
|
||||
(2) Do not load this driver if your device has user space apps that needs to
|
||||
access the crypto hardware. Please make sure to have the qcrypto module
|
||||
disabled/unloaded.
|
||||
Not having the driver loaded, will result in the kernel space apps to use
|
||||
the registered software implementation of the crypto algorithms.
|
||||
|
||||
(3) If your device has Playready application enabled and uses the qcedev module
|
||||
to access the crypto hardware accelarator, please be informed that for
|
||||
performance reasons, the CE hardware will need to be dedicated to playready
|
||||
application. Any other user space or kernel application should be implemented
|
||||
to use the software implemenation of the crypto algorithms.

* cipher_size to data_len -1 are remained
|

* unaltered from packet input area.
|

* @count_c: count-C of the first packet, 32 bit.
|

*
|
||||
*
|
||||
* In one request, multiple packets can be ciphered, and output to the
|
||||
* data_out stream.
|
||||
*
|
||||
* Packet data are layed out contiguously in sequence in data_in,
|
||||
* and data_out area. Every packet is identical size.
|
||||
* If the PDU is not byte aligned, set the data_len value of
|
||||
* to the rounded up value of the packet size. Eg, PDU size of
|
||||
* 253 bits, set the packet size to 32 bytes. Next packet starts on
|
||||
* the next byte boundary.
|
||||
*
|
||||
* For each packet, data from offset 0 to cipher_start
|
||||
* will be left unchanged and output to the data_out area.
|
||||
* This area of the packet can be for the RLC header, which is not
|
||||
* to be ciphered.
|
||||
*
|
||||
* The ciphering of a packet starts from offset cipher_start, for
|
||||
* cipher_size bytes of data. Data starting from
|
||||
* offset cipher_start + cipher_size to the end of packet will be left
|
||||
* unchanged and output to the dataOut area.
|
||||
*
|
||||
* For each packet the input arguments of bearer, direction,
|
||||
* ckey, algoritm have to be the same. count_c is the ciphering sequence
|
||||
* number of the first packet. The 2nd packet's ciphering sequence
|
||||
* number is assumed to be count_c + 1. The 3rd packet's ciphering sequence
|
||||
* number is count_c + 2.....
