[PATCH v5] ASoC: tas2781: Support dsp firmware Alpha and Beta seaies
by Shenghao Ding 03 Mar '25

03 Mar '25

For calibration, basic version does not contain any calibration addresses, it depends on calibration tool to convey the addresses to the driver. Since Alpha and Beta firmware, all the calibration addresses are saved into the firmware. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- v5: - Instead of the lengthy approach, just replace if-continue with else if, has reduced this by 2/3 of LoCs - Use proper error code in fw_parse_fct_param_address() - return directly in tasdevice_dspfw_ready() - drop Unneeded assignment v4: - drop unnecceary "unsigned short size;" and "char *data;" in struct fct_param_address - replace strstr() with strncmp() in fct_param_address_parser() - replace hex_parse_u8() with memcpy() - replace hex_parse_u24() with direct assignment - drop hex_parse_u8() & hex_parse_u24() - Just return directly and use proper error codes and drop "goto out" and "out:" label in fw_parse_fct_param_address - fixed indentation issues in cali_reg_update - fixed the logical splits in tas2781_calib_stop_put() - return -ENOMEM if kmemdup fails in fw_parse_fct_param_address() - remove unnecessary "out:" label v3: - Merge the 4 patches into one patch v2: - | Reported-by: kernel test robot <lkp(a)intel.com> | Closes: | https://urldefense.com/v3/__https://lore.kernel.org/oe-kbuild-all/2025 | 02160812.P7szOygN-lkp(a)intel.com/__;!!G3vK!WriwhtbQGlg6p00bcWutlhb-y9vS | pDrSu5_g9oOzzGOoABdirEARTntFzyX6Ss3UPRDxi_E-IA$ - | Reported-by: kernel test robot <lkp(a)intel.com> | Closes: | https://urldefense.com/v3/__https://lore.kernel.org/oe-kbuild-all/2025 | 02160632.u0zxG7yD-lkp(a)intel.com/__;!!G3vK!VtEdfur3fZklvPVfHFFfFP60Ub2E | JYvmjSUZ65lJ6BsQPJDl1fjYRDqh3c6Q5y6sA70ssXDG5g$ v1: - update the year from 2024 to 2025 in the files. - Add dspbin_type to distinguish different dspbin types, such as TASDEV_BASIC, TASDEV_ALPHA, and TASDEV_BETA. - Add struct bulk_reg_val alp_cali_bckp to store the value of pilot tone threshold only for TASDEV_ALPHA & TASDEV_BETA firmware. - Add the declaration of (*fw_parse_fct_param_address)() to parse the addresses of calibration params. - Add the minimum version of TASDEV_ALPHA and TASDEV_BETA firmware. - Add the definition of struct fct_param_address. - update the year from 2024 to 2025. - release the memory to save calibration addresses in tasdevice_dsp_remove(). - Add TASDEV_ALPHA and TASDEV_BETA firmware checking code. - Add fct_param_address_parser for Alpha and Beta firmware. - Add an extra branch to handle calibration address for TASDEV_ALPHA and TASDEV_BETA firmware. --- include/sound/tas2781-dsp.h | 30 ++++- include/sound/tas2781.h | 11 ++ sound/pci/hda/tas2781_spi_fwlib.c | 8 +- sound/soc/codecs/tas2781-fmwlib.c | 190 ++++++++++++++++++++++---- sound/soc/codecs/tas2781-i2c.c | 215 ++++++++++++++++++++++-------- 5 files changed, 368 insertions(+), 86 deletions(-) diff --git a/include/sound/tas2781-dsp.h b/include/sound/tas2781-dsp.h index 3cda9da14f6d..c3a9efa73d5d 100644 --- a/include/sound/tas2781-dsp.h +++ b/include/sound/tas2781-dsp.h @@ -2,7 +2,7 @@ // // ALSA SoC Texas Instruments TAS2781 Audio Smart Amplifier // -// Copyright (C) 2022 - 2024 Texas Instruments Incorporated +// Copyright (C) 2022 - 2025 Texas Instruments Incorporated // https://www.ti.com // // The TAS2781 driver implements a flexible and configurable @@ -30,8 +30,10 @@ #define PRE_DEVICE_C 0x12 #define PRE_DEVICE_D 0x16 -#define PPC3_VERSION 0x4100 -#define PPC3_VERSION_TAS2781 0x14600 +#define PPC3_VERSION_BASE 0x4100 +#define PPC3_VERSION_TAS2781_BASIC_MIN 0x14600 +#define PPC3_VERSION_TAS2781_ALPHA_MIN 0x4a00 +#define PPC3_VERSION_TAS2781_BETA_MIN 0x19400 #define TASDEVICE_DEVICE_SUM 8 #define TASDEVICE_CONFIG_SUM 64 @@ -106,6 +108,27 @@ struct tasdevice_calibration { struct tasdevice_data dev_data;

[PATCH v4] ASoC: tas2781: Support dsp firmware Alpha and Beta seaies
by Shenghao Ding 03 Mar '25

03 Mar '25

For calibration, basic version does not contain any calibration addresses, it depends on calibration tool to convey the addresses to the driver. Since Alpha and Beta firmware, all the calibration addresses are saved into the firmware. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- v4: - drop unnecceary "unsigned short size;" and "char *data;" in struct fct_param_address - replace strstr() with strncmp() in fct_param_address_parser() - replace hex_parse_u8() with memcpy() - replace hex_parse_u24() with direct assignment - drop hex_parse_u8() & hex_parse_u24() - Just return directly and use proper error codes and drop "goto out" and "out:" label in fw_parse_fct_param_address - fixed indentation issues in cali_reg_update - fixed the logical splits in tas2781_calib_stop_put() - return -ENOMEM if kmemdup fails in fw_parse_fct_param_address() - remove unnecessary "out:" label v3: - Merge the 4 patches into one patch v2: - | Reported-by: kernel test robot <lkp(a)intel.com> | Closes: | https://urldefense.com/v3/__https://lore.kernel.org/oe-kbuild-all/2025 | 02160812.P7szOygN-lkp(a)intel.com/__;!!G3vK!WriwhtbQGlg6p00bcWutlhb-y9vS | pDrSu5_g9oOzzGOoABdirEARTntFzyX6Ss3UPRDxi_E-IA$ - | Reported-by: kernel test robot <lkp(a)intel.com> | Closes: | https://urldefense.com/v3/__https://lore.kernel.org/oe-kbuild-all/2025 | 02160632.u0zxG7yD-lkp(a)intel.com/__;!!G3vK!VtEdfur3fZklvPVfHFFfFP60Ub2E | JYvmjSUZ65lJ6BsQPJDl1fjYRDqh3c6Q5y6sA70ssXDG5g$ v1: - update the year from 2024 to 2025 in the files. - Add dspbin_type to distinguish different dspbin types, such as TASDEV_BASIC, TASDEV_ALPHA, and TASDEV_BETA. - Add struct bulk_reg_val alp_cali_bckp to store the value of pilot tone threshold only for TASDEV_ALPHA & TASDEV_BETA firmware. - Add the declaration of (*fw_parse_fct_param_address)() to parse the addresses of calibration params. - Add the minimum version of TASDEV_ALPHA and TASDEV_BETA firmware. - Add the definition of struct fct_param_address. - update the year from 2024 to 2025. - release the memory to save calibration addresses in tasdevice_dsp_remove(). - Add TASDEV_ALPHA and TASDEV_BETA firmware checking code. - Add fct_param_address_parser for Alpha and Beta firmware. - Add an extra branch to handle calibration address for TASDEV_ALPHA and TASDEV_BETA firmware. --- include/sound/tas2781-dsp.h | 30 ++++- include/sound/tas2781.h | 11 ++ sound/pci/hda/tas2781_spi_fwlib.c | 8 +- sound/soc/codecs/tas2781-fmwlib.c | 214 +++++++++++++++++++++++++---- sound/soc/codecs/tas2781-i2c.c | 216 +++++++++++++++++++++++------- 5 files changed, 395 insertions(+), 84 deletions(-) diff --git a/include/sound/tas2781-dsp.h b/include/sound/tas2781-dsp.h index 3cda9da14f6d..c3a9efa73d5d 100644 --- a/include/sound/tas2781-dsp.h +++ b/include/sound/tas2781-dsp.h @@ -2,7 +2,7 @@ // // ALSA SoC Texas Instruments TAS2781 Audio Smart Amplifier // -// Copyright (C) 2022 - 2024 Texas Instruments Incorporated +// Copyright (C) 2022 - 2025 Texas Instruments Incorporated // https://www.ti.com // // The TAS2781 driver implements a flexible and configurable @@ -30,8 +30,10 @@ #define PRE_DEVICE_C 0x12 #define PRE_DEVICE_D 0x16 -#define PPC3_VERSION 0x4100 -#define PPC3_VERSION_TAS2781 0x14600 +#define PPC3_VERSION_BASE 0x4100 +#define PPC3_VERSION_TAS2781_BASIC_MIN 0x14600 +#define PPC3_VERSION_TAS2781_ALPHA_MIN 0x4a00 +#define PPC3_VERSION_TAS2781_BETA_MIN 0x19400 #define TASDEVICE_DEVICE_SUM 8 #define TASDEVICE_CONFIG_SUM 64 @@ -106,6 +108,27 @@ struct tasdevice_calibration { struct tasdevice_data dev_data;

Fine-grained control bar
by GitHub issues - opened 02 Mar '25

02 Mar '25

alsa-project/alsa-utils issue #295 was opened from egmontkob: The control bars of `alsamixer` are quite coarse. They jump by whole character cells. Often a notable amount of increase or decrease (pressing the Up or Down arrow) isn't reflected visually. I'd like to ask for an opion for more fine-grained looking control bars. If the terminal's / locale's claimed charset, as reported by `nl_langinfo(CODESET)`, is "UTF-8" (as it should be pretty much everywhere nowadays), you could use the Unicode characters [U+2581 to U+2588](https://www.unicode.org/charts/PDF/U2580.pdf) for this purpose. They jump by eighths of a cell's hight. Their foreground color would be the desired bar color (red/white/green) and their background would be the default (or black for `-B`). For consistency, this mode should probably replace the current checkerboard (ACS_CKBOARD) characters by the full block U+2588 and only set its foreground, but maybe this doesn't matter. There are several terminal emulators out there (at least VTE-based ones such as GNOME Terminal and many others; Konsole; and presumably much more) that don't take these glyphs from the font but rather draw them manually to perfectly align them at cell boundaries. In these terminals the bar would look perfectly. In other terminals there might be some ugly gaps at cell boundaries (subject to the selected font), but some people might still prefer this tiny visual glitch over the current coarseness of the bar (again: this would be an option, not a forced new behavior). Thanks for considering this feature request! Issue URL : https://github.com/alsa-project/alsa-utils/issues/295 Repository URL: https://github.com/alsa-project/alsa-utils
