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.

[ 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

Introduction:
=============
This driver provides IOCTLS for user space application to access crypto
engine hardware for the qcedev crypto services. The driver supports the
following crypto algorithms
- AES-128, AES-256 (ECB, CBC and CTR mode)
- AES-192, (ECB, CBC and CTR mode)
(support exists on platform supporting CE 3.x hardware)
- SHA1/SHA256
- AES-128, AES-256 (XTS), AES CMAC, SHA1/SHA256 HMAC
(support exists on platform supporting CE 4.x hardware)
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.

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:

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

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.

(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.
(NOTE: Please refer to details on the limitations listed in qce/40.txt)
