gpu: drm: radeon: Fix a possible null-pointer dereference in radeon_connector_set_property()

2019-10-07T16:54:59+00:00

[ Upstream commit f3eb9b8f67bc28783eddc142ad805ebdc53d6339 ] In radeon_connector_set_property(), there is an if statement on line 743 to check whether connector->encoder is NULL: if (connector->encoder) When connector->encoder is NULL, it is used on line 755: if (connector->encoder->crtc) Thus, a possible null-pointer dereference may occur. To fix this bug, connector->encoder is checked before being used. This bug is found by a static analysis tool STCheck written by us.

drm/radeon: Fix EEH during kexec

[ Upstream commit 6f7fe9a93e6c09bf988c5059403f5f88e17e21e6 ] During kexec some adapters hit an EEH since they are not properly shut down in the radeon_pci_shutdown() function. Adding radeon_suspend_kms() fixes this issue. Signed-off-by: KyleMahlkuch Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

commit cc5034a5d293dd620484d1d836aa16c6764a1c8c upstream. Add missing break statement in order to prevent the code from falling through to case CB_TARGET_MASK. This bug was found thanks to the ongoing efforts to enable -Wimplicit-fallthrough.

drm/radeon: fix mode_valid's return type

2018-08-03T05:50:34+00:00

[ Upstream commit 7a47f20eb1fb8fa8d7a8fe3a4fd8c721f04c2174 ] The method struct drm_connector_helper_funcs::mode_valid is defined as returning an 'enum drm_mode_status' but the driver implementation for this method uses an 'int' for it. Fix this by using 'enum drm_mode_status' in the driver too. Signed-off-by: Luc Van Oostenryck Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

drm/radeon: Fix PCIe lane width calculation

2018-04-24T07:36:36+00:00

commit 85e290d92b4b794d0c758c53007eb4248d385386 upstream. Two years ago I tried an AMD Radeon E8860 embedded GPU with the drm driver. The dmesg output included driver warnings about an invalid PCIe lane width. Tracking the problem back led to si_set_pcie_lane_width_in_smc(). The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere. Applying the increment silenced the warnings. The code has not changed since, so either my analysis was incorrect or the bug has gone unnoticed. Hence submitting this as an RFC.
