Piegdon" +List-Id: + +Hi, +a while back I sent a few mails regarding spurious interrupts in the +UARTA (hsuart) block of the Tegra2 SoC, when using the 8250 driver for +it instead of the hsuart driver. After going down a pretty deep +debugging/testing hole, I think I found a patch that fixes the issue. So +far testing in a reboot-cycle suggests that the error frequency dropped +from >3% of all reboots to at least <0.05% of all reboots. Tests +continue to run over the weekend. + +The patch below already is a second iteration; the first did not reset +the MCR or contain the lines below '// clear interrupts'. This resulted +in no more spurious interrupts, but in a few % of spurious interrupts +that were recovered the UART block did not receive any characters any +more. So further resetting was required to fully reacquire operational +state of the UART block. + +I'd love any comments/suggestions on this! + +Cheers, + +David + +--- a/drivers/tty/serial/8250/8250_core.c ++++ b/drivers/tty/serial/8250/8250_core.c +@@ -134,6 +134,38 @@ static irqreturn_t serial8250_interrupt( + + if (l == i->head && pass_counter++ > PASS_LIMIT) + break; ++ ++#ifdef CONFIG_ARCH_TEGRA_2x_SOC ++ if (!handled && (port->type == PORT_TEGRA)) { ++ /* ++ * Fix Tegra 2 CPU silicon bug where sometimes ++ * "TX holding register empty" interrupts result in a ++ * bad (metastable?) state in Tegras HSUART IP core. ++ * Only way to recover seems to be to reset all ++ * interrupts as well as the TX queue and the MCR. ++ * But we don't want to loose any outgoing characters, ++ * so only do it if the RX and TX queues are empty. ++ */ ++ unsigned char lsr = port->serial_in(port, UART_LSR); ++ const unsigned char fifo_empty_mask = ++ (UART_LSR_TEMT | UART_LSR_THRE); ++ if (((lsr & (UART_LSR_DR | fifo_empty_mask)) == ++ fifo_empty_mask)) { ++ port->serial_out(port, UART_IER, 0); ++ port->serial_out(port, UART_MCR, 0); ++ serial8250_clear_and_reinit_fifos(up); ++ port->serial_out(port, UART_MCR, up->mcr); ++ port->serial_out(port, UART_IER, up->ier); ++ // clear interrupts ++ serial_port_in(port, UART_LSR); ++ serial_port_in(port, UART_RX); ++ serial_port_in(port, UART_IIR); ++ serial_port_in(port, UART_MSR); ++ up->lsr_saved_flags = 0; ++ up->msr_saved_flags = 0; ++ } ++ } ++#endif + } while (l != end); + + spin_unlock(&i->lock); diff --git a/target/linux/tegra/patches-5.15/101-ARM-dtc-tegra-enable-front-panel-leds-in-TrimSlice.patch b/target/linux/tegra/patches-5.15/101-ARM-dtc-tegra-enable-front-panel-leds-in-TrimSlice.patch new file mode 100644 index 0000000000..b1e210b212 --- /dev/null +++ b/target/linux/tegra/patches-5.15/101-ARM-dtc-tegra-enable-front-panel-leds-in-TrimSlice.patch @@ -0,0 +1,46 @@ +--- a/arch/arm/boot/dts/tegra20-trimslice.dts ++++ b/arch/arm/boot/dts/tegra20-trimslice.dts +@@ -201,16 +201,17 @@ + conf_ata { + nvidia,pins = "ata", "atc", "atd", "ate", + "crtp", "dap2", "dap3", "dap4", "dta", +- "dtb", "dtc", "dtd", "dte", "gmb", +- "gme", "i2cp", "pta", "slxc", "slxd", +- "spdi", "spdo", "uda"; ++ "dtb", "dtc", "dtd", "gmb", "gme", ++ "i2cp", "pta", "slxc", "slxd", "spdi", ++ "spdo", "uda"; + nvidia,pull = ; + nvidia,tristate = ; + }; + conf_atb { + nvidia,pins = "atb", "cdev1", "cdev2", "dap1", +- "gma", "gmc", "gmd", "gpu", "gpu7", +- "gpv", "sdio1", "slxa", "slxk", "uac"; ++ "dte", "gma", "gmc", "gmd", "gpu", ++ "gpu7", "gpv", "sdio1", "slxa", "slxk", ++ "uac"; + nvidia,pull = ; + nvidia,tristate = ; + }; +@@ -396,6 +397,20 @@ + }; + }; + ++ gpio-leds { ++ compatible = "gpio-leds"; ++ ++ ds2 { ++ label = "trimslice:green:right"; ++ gpios = <&gpio TEGRA_GPIO(D, 2) GPIO_ACTIVE_LOW>; ++ }; ++ ++ ds3 { ++ label = "trimslice:green:left"; ++ gpios = <&gpio TEGRA_GPIO(BB, 5) GPIO_ACTIVE_LOW>; ++ }; ++ }; ++ + poweroff { + compatible = "gpio-poweroff"; + gpios = <&gpio TEGRA_GPIO(X, 7) GPIO_ACTIVE_LOW>;
