At enumeration, imprecise aborts are not enabled -thus this ends up getting deferred until the kernel has completed init. At -that point we must not adjust PC - the handler must do nothing, but a handler -must exist. - -This fixes random crashes that occur right after freeing init. -This is against linux-pci/host-imx6. - -Acked-by: Marek Vasut <marex@denx.de> -Tested-by: Marek Vasut <marex@denx.de> -Signed-off-by: Tim Harvey <tharvey@gateworks.com> ---- - drivers/pci/host/pci-imx6.c | 6 ------ - 1 file changed, 6 deletions(-) - ---- a/drivers/pci/host/pci-imx6.c -+++ b/drivers/pci/host/pci-imx6.c -@@ -200,12 +200,6 @@ static int pcie_phy_write(void __iomem * - static int imx6q_pcie_abort_handler(unsigned long addr, - unsigned int fsr, struct pt_regs *regs) - { -- /* -- * If it was an imprecise abort, then we need to correct the -- * return address to be _after_ the instruction. -- */ -- if (fsr & (1 << 10)) -- regs->ARM_pc += 4; - return 0; - } - |
