On google/sarien, the (upstream) Linux kernel sometimes detects the Melfas touchscreen and sometimes not, but in never works. When it’s detected, the errors below are still shown. ``` $ grep i2c voidlinux-linux-5.13.19-messages.txt [ 9.392598] i2c i2c-7: 2/2 memory slots populated (from DMI) [ 9.393108] i2c i2c-7: Successfully instantiated SPD at 0x50 [ 9.622151] input: MELFAS MIP4 Touchscreen as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-8/i2c-MLFS0000:00/input/input6 [ 9.657964] cr50_i2c i2c-GOOG0005:00: cr50 TPM 2.0 (i2c 0x50 irq 114 id 0x28) [ 9.662309] elan_i2c i2c-ELAN0000:00: supply vcc not found, using dummy regulator [ 9.773244] elan_i2c i2c-ELAN0000:00: Elan Touchpad: Module ID: 0x00d6, Firmware: 0x0005, Sample: 0x0009, IAP: 0x0001 [ 9.773349] input: Elan Touchpad as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-9/i2c-ELAN0000:00/input/input7 [ 10.820307] i2c_designware i2c_designware.0: controller timed out [ 10.820359] mip4_ts i2c-MLFS0000:00: mip4_i2c_xfer - i2c_transfer failed: -110 (-110) [ 11.844523] i2c_designware i2c_designware.0: controller timed out [ 11.844635] mip4_ts i2c-MLFS0000:00: mip4_i2c_xfer - i2c_transfer failed: -110 (-110) [ 12.868376] i2c_designware i2c_designware.0: controller timed out [ 12.868488] mip4_ts i2c-MLFS0000:00: mip4_i2c_xfer - i2c_transfer failed: -110 (-110) [ 12.868570] mip4_ts i2c-MLFS0000:00: Failed to read packet info: -110 ``` Is that related to the probing stuff? >> If we wanted to do this correctly, coreboot would have to implement >> full power and reset control and also add drivers for I2C controllers >> to be able to communicate with peripherals, and then adjust _STA >> methods to report "not present" when the device is indeed absent.

What do you mean by “bootloader mode”? coreboot also cannot flash anything. That’s up to the payload, and even there support for flashing is rare. Duncan wrote something about the ACPI _STA method idea, that ASL(?) and I2C do not go well together. >> However coreboot does (or did?) not want to add code to handle i2c >> controllers, and would like to push this knowledge to the kernel. And >> the kernel does know how to handle peripherals properly, but that >> knowledge lies in individual drivers, not i2c core. Excuse my ignorance, can you give an example driver? Does the Melfas touchscreen driver (`drivers/input/touchscreen/melfas_mip4.c`) support it? >> We should remove "linux,probed" from coreboot and not propagate to >> newer Chrome OS kernels, and keep it away from upstream. > > Revert from chromeos-5.15 is at > https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/3350347. > Everyone please feel free to comment there. Guenther, thank you for your quick response. Note, that neither Furquan, nor Aaron, nor Duncan work at Google anymore, so won’t comment. Hopefully, others from the Chromium OS/coreboot folks can chime in.
