This was reverted and then the -system got a DSP exception when the DSP registers were saved in -save_dsp() in the first process switch. The crash looks like this: - -[ 0.089999] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) -[ 0.097796] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear) -[ 0.107070] Kernel panic - not syncing: Unexpected DSP exception -[ 0.113470] Rebooting in 1 seconds.. - -We saw this problem in OpenWrt only on the MIPS 74Kc based Atheros SoCs, -not on the 24Kc based SoCs. We only saw it with kernel 5.4 not with -kernel 4.19, in addition we had to use GCC 8.4 or 9.X, with GCC 8.3 it -did not happen. - -In the kernel I bisected this problem to commit 9012d011660e ("compiler: -allow all arches to enable CONFIG_OPTIMIZE_INLINING"), but when this was -reverted it also happened after commit 172dcd935c34b ("MIPS: Always -allocate exception vector for MIPSr2+"). - -Commit 0b24cae4d535 ("MIPS: Add missing EHB in mtc0 -> mfc0 sequence.") -does similar changes to a different file. I am not sure if there are -more places affected by this problem. - -Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> -Cc: <stable@vger.kernel.org> ---- - arch/mips/kernel/traps.c | 1 + - 1 file changed, 1 insertion(+) - ---- a/arch/mips/kernel/traps.c -+++ b/arch/mips/kernel/traps.c -@@ -2096,6 +2096,7 @@ static void configure_status(void) - - change_c0_status(ST0_CU|ST0_MX|ST0_RE|ST0_FR|ST0_BEV|ST0_TS|ST0_KX|ST0_SX|ST0_UX, - status_set); -+ back_to_back_c0_hazard(); - } - - unsigned int hwrena; diff --git a/target/linux/generic/pending-4.19/810-pci_disable_common_quirks.patch b/target/linux/generic/pending-4.19/810-pci_disable_common_quirks.patch index 669229c620..c757aeeaad 100644 --- a/target/linux/generic/pending-4.19/810-pci_disable_common_quirks.patch +++ b/target/linux/generic/pending-4.19/810-pci_disable_common_quirks.patch @@ -33,7 +33,7 @@ Signed-off-by: Gabor Juhos <juhosg@openwrt.org> /* * The Mellanox Tavor device gives false positive parity errors.
