2020-02-27Add WrEndPointConfig MMIO to peci_cmdsJason M. Bills1-0/+42
This adds WrEndPointConfig MMIO support to the peci_cmds utility. Tested: Ran this command: peci_cmds WrEndpointConfigMMIO 6 0 0 0x7e 0x1a 0x0 0x224e0 0x5f5a56 and got the expected command buffer in the driver log: [ 795.207278] peci_aspeed 1e78b000.peci-bus: HEAD : 0x00011730 [ 795.212980] TX : c5 00 05 00 00 00 06 00 d0 7e e0 24 02 00 00 00 .........~.$....

2020-02-27Add WrEndPointConfig MMIO to the PECI libraryJason M. Bills2-0/+85
This adds WrEndPointConfig MMIO support to the PECI library. Tested: Combined with the peci_cmds change, ran this command: peci_cmds WrEndpointConfigMMIO 6 0 0 0x7e 0x1a 0x0 0x224e0 0x5f5a56 and got the expected command buffer in the driver log: [ 795.207278] peci_aspeed 1e78b000.peci-bus: HEAD : 0x00011730 [ 795.212980] TX : c5 00 05 00 00 00 06 00 d0 7e e0 24 02 00 00 00 .........~.$....

2020-02-07Print the completion code on errorJason M. Bills1-0/+11
In some cases, such as timeout, the PECI completion code can still provide additional data, so print it along with the error code. Tested: peci_cmds RdPCIConfig 0 0 0 ERROR 6: command failed cc:0x40 Change-Id: Ib4e8cdc5f6c45e2cd873df344a4e5d2e237a98ee Signed-off-by: Jason M. Bills <jason.m.bills@linux.intel.com>
2020-02-06Add PECI_CC_TIMEOUT responseJason M. Bills2-0/+6
If the driver times-out on a PECI call and returns ETIMEDOUT, return a new PECI_CC_TIMEOUT response to the caller. Tested: Ran a PECI command with a timeout and confirmed that it returns PECI_CC_TIMEOUT. Change-Id: I93e25948ef05d0e7f137500310a4dfa99ed8980c Signed-off-by: Jason M.

2019-12-05Fix the peci_cmds utilityKarthick Sundarrajan1-53/+53
At present, the peci_cmds utility just accepts hex for all numerical inputs. Fixed it to accept numericals in decimal or hex or octals. Tested: The index and Param in the output are in hex. root@intel-obmc:~# peci_cmds rdpkgconfig 10 16 -v PECI target[0x30]: Pkg Read of Index 0a Param 0010 cc:0x40 0x00000a9c root@intel-obmc:~# peci_cmds rdpkgconfig 0x10 0x16 -v PECI target[0x30]: Pkg Read of Index 10 Param 0016 cc:0x40 0x00690a00 Change-Id: Idce477653de9ad394b857196b652c66bd02e1e5c Signed-off-by: Karthick Sundarrajan <karthick.sundarrajan@intel.com>

2019-11-26Separate stepping from model in peci_GetCPUID()Jason M. Bills2-12/+17
Including the stepping in the CPUID was too granular and was causing a lot of unnecessary updates to code that uses it. This change returns the CPU model as the main parameter for identifying the processor and gives the stepping as a separate parameter in case it is needed. Tested: Combined with the changes in the consumers of this library, verified that the CPU model can correctly be retreived and used to determine the correct PECI calls to use.

2019-10-23Enable build flags and fix warningsJason M. Bills4-73/+104
This enables warnings during the build and fixes some warnings so it builds successfully. Tested: Confirmed that it builds and peci_cmds still works as expected. Change-Id: I768f2bc78050d001f6500b7349cceb40086def07 Signed-off-by: Jason M. Bills <jason.m.bills@linux.intel.com>
2019-10-16Handle the address and size parameters betterJason M. Bills1-6/+20
Instead of atoi() which has no error handling, switch to strtoul() so failures will return 0 and check the acceptable size and address ranges.

2019-10-15Change peci_cmds interface to use a string for the commandJason M. Bills1-450/+395
The dash options to select commands will become very cumbersome as we implement the new PECI 4.0 commands. This separates the parameters into 'options' and 'commands'. Options are set using the dash parameters as they are today. Commands are now selected by a string in the first parameter. This is inspired by the usage of ipmitool and will hopefully feel familiar. This will help as new command types are added so we don't end up overloading the dash options with too many types that have to be checked against the help every time. Tested: Executed the following commands and confirmed they behave as expected: ./peci_cmds -h Usage: ./peci_cmds [-a <addr>] [-s <size>] <command> [parameters] Options: -h Display this help information -a Address of the target in decimal. Default is 48 -s Size of data to read or write in bytes.

2019-10-15Clean up peci_cmds outputJason M. Bills1-111/+80
peci_cmds output is not very uniform and leaves out information such as the PECI completion code and library return value that are useful for debug. This change prints the completion code by default and cleans up some of the output to be more uniform. Tested: peci_cmds -c 0 0 PECI target[48]: Pkg Read of Index 00 Param 0000: cc:0x40 0x00050654 peci_cmds -c 0 100 PECI target[48]: Pkg Read of Index 00 Param 0100: cc:0x90 0x00000000 peci_cmds -lw d 0 3 270 15 PECI target[48]: Local PCI Write of 0d:00:03 Reg 270: 0x00000015 cc:0x90 Change-Id: I9094c7c77521ea381006b972aea2bf98e8c200cf Signed-off-by: Jason M.

2019-10-09Allow raw PECI ping commandsJason M. Bills1-1/+1
The PECI ping command has a read length of zero, so when it's called the response buffer is NULL since it has a size of zero. This change allows the command to continue with a NULL response buffer pointer as long as the read length is zero. Tested: Sent a raw ping command to a present CPU and got a successful response. Sent a raw ping command to a not-present CPU and got a failed response. Sent a raw read package config command and got the expected data.
