<li style="margin-top: 0; line-height: 1.6em; margin-left: 25px; padding-left: 3px;">I figured out the workflow of SPI interrupt mode and added interrupt mode to SPI driver. I mainly referred to <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; vertical-align: bottom; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>dev/bsps/shared/dev/spi/cadence-spi.c</code>. SSD1306 works fine both in interrupt mode and polling mode. I shorted MOSI and MISO and did a full duplex test with ioctl(), It works fine in both modes.</li>
