04:23 <anarsoul> haha, workaround for puma to use sysreset-gpio is broken in mainline u-boot

04:23 <anarsoul> #if defined(SPL_GPIO_SUPPORT) ensures it never compiles

04:24 <anarsoul> with defines fixed it lacks an include with 'struct rk3399_cru' definition

04:24 <anarsoul> with this fixed it still fails to get gpio from dts

04:24 <anarsoul> WTF

04:26 camus has joined #linux-rockchip

04:26 <anarsoul> broken by 07586ee4322abca01db52624b925e5218538f259 ("rockchip: rk3399: Support common spl_board_init")

04:26 <anarsoul> Jagan never tests his code.

04:31 <anarsoul> kevery: I'd recommend triple-checking everything from Jagan

04:32 <anarsoul> see my reply to "[PATCH v2 2/8] rockchip: rk3399: Support common spl_board_init", you're in CC

04:33 <anarsoul> kevery: btw, RK3399 TRM says: "2.9.4 Global software reset": "Glb_srstn_1 resets almost all logic."

04:33 <kevery> I check mainline U-Boot this morning, and it works on rk3399 evb/firefly

04:33 <anarsoul> why it's almost?

04:33 <anarsoul> and what's missing?

04:34 <kevery> some logic at always on domain?

04:35 <anarsoul> arch/arm/mach-rockchip/rk3399/rk3399.c:spl_board_init() mentions some fixes to prevent issues during boot-up after soft reset

04:35 <anarsoul> what are these fixes?

04:36 <anarsoul> kevery: btw, are you using blobless u-boot? I.e. mainline u-boot with SPL and with mainline ATF?

04:37 <kevery> I didn't use mainline ATF now

04:37 <anarsoul> OK, so try it with mainline ATF?

04:38 <anarsoul> linux uses PSCI to reboot the board and it's handled by ATF

04:42 <kevery> The power on reset logic is from puma-rk3399, I do not actually met this kind of issue.

05:12 <flacks> anyone else getting secondary cpus disabled / machine hang on heavy decryption on a rockpro64?

05:12 <flacks> anarsoul: ^

05:13 <anarsoul> haven't tried decrypting anything

05:13 <flacks> this is with Linux 5.4

05:13 <anarsoul> anyway, make sure you have my patch for syr83x applied

05:13 <anarsoul> it's not in 5.4

05:13 <anarsoul> flacks: can I see your dmesg?

05:26 <anarsoul> flacks: likely you need this patch: https://lore.kernel.org/lkml/20191106161211.1700663-1-anarsoul@gmail.com/

08:50 <kevery> anarsoul: I don't understand why do you need "enable force power on reset workaround"

08:52 <kevery> anarsoul: I check the schematic of rockpro64, the VSEL of SYR837PKC will be low(RK3399 pull down) after glb_srstn_1 is set，this should be the correct state, why do you need to set the io to HIGH in U-Boot?
