ice_read_phy_tstamp_e82x(9)
π NAME π
okay so bestie, welcome to the ice_read_phy_tstamp_e82x(9) page from the Kernel API Manual π
this one is literally about reading a PHY timestamp out of the quad block β¨
π SYNOPSIS π
int ice_read_phy_tstamp_e82x (struct ice_hw *hw , u8 quad , u8 idx , u64
*tstamp );
π¦ ARGUMENTS π¦
hwβ pointer to the HW struct π«Άquadβ the quad to read from πidxβ the timestamp index to read βtstampβ on return, the40bittimestamp value π
πΈ DESCRIPTION πΈ
So the vibe is: this reads a 40bit timestamp value out of the two associated registers in the quad memory block that is shared between the internal PHYs of the E822 family of devices ππ that's the whole move, no cap.
