Hi,
i.MX93 thermal trip is wrong in imx93.dtsi
thermal-zones {
cpu-thermal {
polling-delay-passive = <250>;
polling-delay = <2000>;
thermal-sensors = <&tmu 0>;
trips {
cpu_alert: cpu-alert {
temperature = <80000>;
hysteresis = <2000>;
type = "passive";
};
cpu_crit: cpu-crit {
temperature = <90000>;
hysteresis = <2000>;
type = "critical";
};
};
cooling-maps {
map0 {
trip = <&cpu_alert>;
cooling-device =
<&A55_0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>,
<&A55_1 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
};
};
};
};
It's 80 degree on alert, 90 degree on crit.
It's different from u-boot log
u32 get_cpu_temp_grade(int *minc, int *maxc)
{
int ret;
u32 val;
ret = fuse_read(2, 3, &val);
if (ret)
val = 0; /* If read fuse failed, return as blank fuse */
val >>= 4;
val &= 0x3;
if (minc && maxc) {
if (val == TEMP_AUTOMOTIVE) {
*minc = -40;
*maxc = 125;
} else if (val == TEMP_INDUSTRIAL) {
*minc = -40;
*maxc = 105;
} else if (val == TEMP_EXTCOMMERCIAL) {
if (is_imx93()){
/* imx93 only has extended industrial*/
*minc = -40;
*maxc = 125;
} else {
*minc = -20;
*maxc = 105;
}
} else {
*minc = 0;
*maxc = 95;
}
}
return val;
}
Which i.MX8M PLUS remains the same as commercial grade.
-------
This leads to kernel reboot when it reach to 90 degree.
And branch 'lf-6.6.y' is not change yet.
Does this setting has some consideration?
Or I can just modify by my self?
