[PATCH] drm/radeon: avoid a possible array overflow

From: Young Xiao When looking up the connector type make sure the index is valid. Avoids a later crash if we read past the end of the array. See commit e1718d97aa88 ("drm/amdgpu: avoid a possible array overflow") for detail. Signed-off-by: Young Xiao ---

[PATCH] drm/i915: avoid division by zero on skl_calc_wrpll_link

From: Young Xiao If for some unexpected reason the registers all read zero it's better to WARN and return instead of dividing by zero and completely freezing the machine. See commit 0e005888b833 ("drm/i915: avoid division by zero on cnl_calc_wrpll_link") for detail. Signed-off-by: Young Xiao

[PATCH] drm: radeon: fix overflow on 32bit systems

From: Young Xiao the type mem->start is unsigned long, so this can overflow on 32bit system, since the type addr is uint64_t. Signed-off-by: Young Xiao --- drivers/gpu/drm/radeon/radeon_vm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/radeon/radeon_vm.c

[PATCH] drm/amd/amdgpu: Test for PCI root bus before assuming bus->self

From: Young_X If we assign an amd device to a virtual mechine, we can no longer assume a fixed hardware topology, like the GPU having a parent device. This patch simply adds pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions. See commit
