[REGRESSION] Asus X541UAK hangs on suspend and poweroff (v6.1.6 onward)

by Acid Bong

Hi there, hello, Sometimes when I suspend (by closing the lid, less often - by pressing Fn+F1 (sleep key combo)) or poweroff my laptop (both by pressing powerit button and running "loginctl poweroff"), it goes in such a state when it doesn't respond to opening/closing the lid, power button nor Ctrl+Alt+Del, but, unlike in sleep mode, the fan is rotating and the "awake status" LED is on. I checked /var/log/kern.log, but it didn't report suspend at that moment at all: went straight from [UFW BLOCK] to "Microcode updated" on force reboot (marked with an arrow): Apr 13 10:40:32 bong kernel: asus_wmi: Unknown key code 0xcf Apr 13 10:44:05 bong kernel: [UFW BLOCK] IN=wlan0 OUT= MAC=/*confidential*/ Apr 13 10:47:45 bong kernel: [UFW BLOCK] IN=wlan0 OUT= MAC=/*confidential*/ Apr 13 10:47:46 bong kernel: ICMPv6: NA: /*router*/ advertised our address /*ipv6*/ on wlan0!

I used that fork until 6.2-pf2, but since then (early March) moved to vanilla sources and started following the 6.1.y branch when it was declared LTS. And the issue was present on all of them. The hang was last detected 3 days ago on 6.1.22 and today on 6.1.23. I'd like to bisect it, but it could take ages for a couple of reasons: 1) I don't know exact patterns it follows. One of the scenarios I've noticed was this one (sorry if too ridiculous): - put the laptop on the nearby couch and simultaneously close the lid; the loose charger jack might disconnect; - lay the mouse upside down (so it doesn't wake up when I reconnect the charger), but it's not a 100% guarantee of the bug and, as I said earlier, the laptop also misbehaves on shutdown. 2) The issue happens rarely, once in a few days (sometimes up to a week; I haven't measured it precisely back then). Hardware: https://tilde.cafe/u/acidbong/kernel/lspci (`lspci -vvnn`) Config (latest vanilla): https://git.sr.ht/~acid-bong/kernel/tree/806e6639da610952798e1b5d8c0d700062… Built with KCFLAGS="-march=native" Isolated cmdline: root=/dev/genston/root ro loglevel=4 rd.lvm.vg=genston rd.luks.uuid=97d10669-2da1-452d-a372-887e420b2ad4 rd.luks.allow-discards pci=nomsi initrd=\initramfs-6.1.23-bong+.img # regzbot introduced v6.1.3..v6.1.6 --- Regards, ~acidbong

Yeah of course. Maybe Sebastian can fix with a bit of git commit --amend when applying? Thanks! Yours, Linus Walleij

[PATCH v5] drm/dp_mst: Clear MSG_RDY flag before sending new message

by Wayne Lin

[Why] The sequence for collecting down_reply from source perspective should be: Request_n->repeat (get partial reply of Request_n->clear message ready flag to ack DPRX that the message is received) till all partial replies for Request_n are received->new Request_n+1. Now there is chance that drm_dp_mst_hpd_irq() will fire new down request in the tx queue when the down reply is incomplete. Source is restricted to generate interveleaved message transactions so we should avoid it. Also, while assembling partial reply packets, reading out DPCD DOWN_REP Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be wrapped up as a complete operation for reading out a reply packet. Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might be risky. e.g. If the reply of the new request has overwritten the DPRX DOWN_REP Sideband MSG buffer before source writing one to clear DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply for the new request. Should handle the up request in the same way. [How] Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might trigger drm_dp_mst_kick_tx() only when there is no on going message transaction. Changes since v1: * Reworked on review comments received -> Adjust the fix to let driver explicitly kick off new down request when mst irq event is handled and acked -> Adjust the commit message Changes since v2: * Adjust the commit message * Adjust the naming of the divided 2 functions and add a new input parameter "ack". * Adjust code flow as per review comments. Changes since v3: * Update the function description of drm_dp_mst_hpd_irq_handle_event Changes since v4: * Change ack of drm_dp_mst_hpd_irq_handle_event() to be an array align the size of esi[] Signed-off-by: Wayne Lin <Wayne.Lin(a)amd.com> Cc: stable(a)vger.kernel.org --- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 32 +++++------ drivers/gpu/drm/display/drm_dp_mst_topology.c | 54 ++++++++++++++++--- drivers/gpu/drm/i915/display/intel_dp.c | 7 +-- drivers/gpu/drm/nouveau/dispnv50/disp.c | 12 +++-- include/drm/display/drm_dp_mst_helper.h | 7 ++- 5 files changed, 81 insertions(+), 31 deletions(-) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index d5cec03eaa8d..ec629b4037e4 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -3263,6 +3263,7 @@ static void dm_handle_mst_sideband_msg(struct amdgpu_dm_connector *aconnector) while (dret == dpcd_bytes_to_read && process_count < max_process_count) { + u8 ack[DP_PSR_ERROR_STATUS - DP_SINK_COUNT_ESI] = {}; u8 retry; dret = 0; @@ -3271,28 +3272,29 @@ static void dm_handle_mst_sideband_msg(struct amdgpu_dm_connector *aconnector) DRM_DEBUG_DRIVER("ESI %02x %02x %02x\n", esi[0], esi[1], esi[2]); /* handle HPD short pulse irq */ if (aconnector->mst_mgr.mst_state) - drm_dp_mst_hpd_irq( - &aconnector->mst_mgr, - esi, - &new_irq_handled); + drm_dp_mst_hpd_irq_handle_event(&aconnector->mst_mgr, + esi, + ack, + &new_irq_handled); if (new_irq_handled) { /* ACK at DPCD to notify down stream */ - const int ack_dpcd_bytes_to_write = - dpcd_bytes_to_read - 1; - for (retry = 0; retry < 3; retry++) { - u8 wret; - - wret = drm_dp_dpcd_write( - &aconnector->dm_dp_aux.aux, - dpcd_addr + 1, - &esi[1], - ack_dpcd_bytes_to_write); - if (wret == ack_dpcd_bytes_to_write) + ssize_t wret; + + wret = drm_dp_dpcd_writeb(&aconnector->dm_dp_aux.aux, + dpcd_addr + 1, + ack[1]); + if (wret == 1) break; } + if (retry == 3) { + DRM_ERROR("Failed to ack MST event.\n"); + return; + } + + drm_dp_mst_hpd_irq_send_new_request(&aconnector->mst_mgr); /* check if there is new irq to be handled */ dret = drm_dp_dpcd_read( &aconnector->dm_dp_aux.aux, diff --git a/drivers/gpu/drm/display/drm_dp_mst_topology.c b/drivers/gpu/drm/display/drm_dp_mst_topology.c index 38dab76ae69e..487d057a9582 100644 --- a/drivers/gpu/drm/display/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/display/drm_dp_mst_topology.c @@ -4053,17 +4053,28 @@ static int drm_dp_mst_handle_up_req(struct drm_dp_mst_topology_mgr *mgr) } /** - * drm_dp_mst_hpd_irq() - MST hotplug IRQ notify + * drm_dp_mst_hpd_irq_handle_event() - MST hotplug IRQ handle MST event * @mgr: manager to notify irq for. * @esi: 4 bytes from SINK_COUNT_ESI + * @ack: 4 bytes used to ack events starting from SINK_COUNT_ESI * @handled: whether the hpd interrupt was consumed or not * - * This should be called from the driver when it detects a short IRQ, + * This should be called from the driver when it detects a HPD IRQ, * along with the value of the DEVICE_SERVICE_IRQ_VECTOR_ESI0.
