This utility allows to convert the configuration DW0/1 registers value from inteltool dump to coreboot macros.
(shell)$ make (shell)$ ./intelp2m -h (shell)$ ./intelp2m -file /path/to/inteltool.log
It is possible to use templates for parsing files of excellent inteltool.log. To specify such a pattern, use the option -t . For example, using template type # 1, you can parse gpio.h from an already added board in the coreboot project.
(shell)$ ./intelp2m -h -t template type number 0 - inteltool.log (default) 1 - gpio.h 2 - your template (shell)$ ./intelp2m -t 1 -file coreboot/src/mainboard/yourboard/gpio.h
You can also add a template to 'parser/template.go' for your file type with the configuration of the pads.
platform type is set using the -p option (Sunrise by default):
-p string set up a platform snr - Sunrise PCH with Skylake/Kaby Lake CPU lbg - Lewisburg PCH with Xeon SP CPU apl - Apollo Lake SoC cnl - CannonLake-LP or Whiskeylake/Coffeelake/Cometlake-U SoC adl - AlderLake PCH (default "snr") (shell)$ ./intelp2m -p <platform> -file path/to/inteltool.log
Use the -fld=cb option to only generate a sequence of bit fields in a new macro:
(shell)$ ./intelp2m -fld cb -p apl -file ../apollo-inteltool.log
_PAD_CFG_STRUCT(GPIO_37, PAD_FUNC(NF1) | PAD_TRIG(OFF) | PAD_TRIG(OFF), PAD_PULL(DN_20K)), /* LPSS_UART0_TXD */
To generate the gpio.c with raw PAD_CFG_DW0 and PAD_CFG_DW1 register values you need to use the -fld=raw option:
(shell)$ ./intelp2m -fld raw -file /path/to/inteltool.log
_PAD_CFG_STRUCT(GPP_A10, 0x44000500, 0x00000000),
(shell)$ ./intelp2m -iiii -fld raw -file /path/to/inteltool.log
/* GPP_A10 - CLKOUT_LPC1 */ /* DW0: 0x44000500, DW1: 0x00000000 */ /* DW0: 0x04000100 - IGNORED */ /* PAD_CFG_NF(GPP_A10, NONE, DEEP, NF1), */ _PAD_CFG_STRUCT(GPP_A10, 0x44000500, 0x00000000),
After generating the macro, the utility checks all used fields of the configuration registers. If some field has been ignored, the utility generates field macros. To not check macros, use the -n option:
(shell)$ ./intelp2m -n -file /path/to/inteltool.log
In this case, some fields of the configuration registers DW0 will be ignored.
PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_38, UP_20K, DEEP, NF1, HIZCRx1, DISPUPD), PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD),
The utility can generate additional information about the bit fields of the DW0 and DW1 configuration registers. Using the options -i, -ii, -iii, -iiii you can set the info level from 1 to 4:
(shell)$./intelp2m -i -file /path/to/inteltool.log
_PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)), /* LPSS_UART0_TXD */
(shell)$./intelp2m -ii -file /path/to/inteltool.log (shell)$./intelp2m -iii -file /path/to/inteltool.log (shell)$./intelp2m -iiii -file /path/to/inteltool.log
/* GPIO_39 - LPSS_UART0_TXD */ /* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii) /* DW0 : PAD_TRIG(OFF) - IGNORED */ --> (iii) /* PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD), */ --> (iiii) _PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)),
If the -n switch was used and macros was generated without checking:
/* GPIO_39 - LPSS_UART0_TXD */ --> (i) /* DW0: 0x44000400, DW1: 0x00003100 */ --> (ii) /* DW0: PAD_TRIG(OFF) - IGNORED */ --> (iii) /* _PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP) | PAD_TRIG(OFF), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)), */ --> (iiii) PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD),
Utilities can generate the PAD_CFG_STRUCT macro and exclude fields from it that are not in the corresponding PAD_CFG*() macro:
(shell)$ ./intelp2m -iiii -fld cb -ign -file /path/to/inteltool.log
/* GPIO_39 - LPSS_UART0_TXD */ /* DW0: 0x44000400, DW1: 0x00003100 */ /* DW0: PAD_TRIG(OFF) - IGNORED */ /* PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_39, UP_20K, DEEP, NF1, TxLASTRxE, DISPUPD), */ _PAD_CFG_STRUCT(GPIO_39, PAD_FUNC(NF1) | PAD_RESET(DEEP), PAD_PULL(UP_20K) | PAD_IOSTERM(DISPUPD)),
The utility allows to generate macros that include fsp/edk2-palforms style bitfields:
(shell)$ ./intelp2m -i -fld fsp -p lbg -file ../crb-inteltool.log
{ GPIO_SKL_H_GPP_A12, { GpioPadModeGpio, GpioHostOwnAcpi, GpioDirInInvOut, GpioOutLow, GpioIntSci | GpioIntLvlEdgDis, GpioResetNormal, GpioTermNone, GpioPadConfigLock }, /* GPIO */
(shell)$ ./intelp2m -iiii -fld fsp -p lbg -file ../crb-inteltool.log
/* GPP_A12 - GPIO */ /* DW0: 0x80880102, DW1: 0x00000000 */ /* PAD_CFG_GPI_SCI(GPP_A12, NONE, PLTRST, LEVEL, INVERT), */ { GPIO_SKL_H_GPP_A12, { GpioPadModeGpio, GpioHostOwnAcpi, GpioDirInInvOut, GpioOutLow, GpioIntSci | GpioIntLvlEdgDis, GpioResetNormal, GpioTermNone, GpioPadConfigLock },
