soc: qcom: mdt_loader: Actually use the e_phoff

2025-08-20T16:35:59+00:00

[ Upstream commit 47e339cac89143709e84a3b71ba8bd9b2fdd2368 ] Rather than relying/assuming that the tools generating the firmware places the program headers immediately following the ELF header, use e_phoff as intended to find the program headers.

Taking the element's address of that type and interpret it as a smaller sized ones works fine for little endian platforms but not for big endian ones. Instead use temporary variables of smaller sized types and cast them correctly to support big endian platforms.

soc: qcom: pmic_glink_altmode: fix spurious DP hotplug events

2025-06-27T10:13:05+00:00

commit 5090ac9191a19c61beeade60d3d839e509fab640 upstream. The PMIC GLINK driver is currently generating DisplayPort hotplug notifications whenever something is connected to (or disconnected from) a port regardless of the type of notification sent by the firmware. These notifications are forwarded to user space by the DRM subsystem as connector "change" uevents: KERNEL[1556.223776] change /devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 (drm) ACTION=change DEVPATH=/devices/platform/soc@0/ae00000.display-subsystem/ae01000.display-controller/drm/card0 SUBSYSTEM=drm HOTPLUG=1 CONNECTOR=36 DEVNAME=/dev/dri/card0 DEVTYPE=drm_minor SEQNUM=4176 MAJOR=226 MINOR=0 On the Lenovo ThinkPad X13s and T14s, the PMIC GLINK firmware sends two identical notifications with orientation information when connecting a charger, each generating a bogus DRM hotplug event. On the X13s, two such notification are also sent every 90 seconds while a charger remains connected, which again are forwarded to user space: port = 1, svid = ff00, mode = 255, hpd_state = 0 payload = 01 00 00 00 00 00 00 ff 00 00 00 00 00 00 00 00 Note that the firmware only sends on of these when connecting an ethernet adapter. Fix the spurious hotplug events by only forwarding hotplug notifications for the Type-C DisplayPort service id. This also reduces the number of uevents from four to two when an actual DisplayPort altmode device is connected: port = 0, svid = ff01, mode = 2, hpd_state = 0 payload = 00 01 02 00 f2 0c 01 ff 03 00 00 00 00 00 00 00 port = 0, svid = ff01, mode = 2, hpd_state = 1 payload = 00 01 02 00 f2 0c 01 ff 43 00 00 00 00 00 00 00 Fixes: 080b4e24852b ("soc: qcom: pmic_glink: Introduce altmode support") Cc: stable@vger.kernel.org # 6.3 Cc: Bjorn Andersson Reported-by: Clayton Craft Signed-off-by: Johan Hovold Acked-by: Konrad Dybcio Tested-by: Clayton Craft Link: https://lore.kernel.org/r/20250324132448.6134-1-johan+linaro@kernel.org Signed-off-by: Bjorn Andersson Signed-off-by: Greg Kroah-Hartman

Qualcomm driver fixes for v6.14 Fixes a locking issue in the PDR implementation, which manifest itself as transaction timeouts during the startup procedure for some remoteprocs. A registration race is fixed in the custom efivars implementation, resolving reported NULL pointer dereferences. Error handling related to tzmem allocation is corrected, to ensure that the allocation error is propagated.
