Miller" , netdev@vger.kernel.org, linux-kernel@vger.kernel.org Subject: net: wwan: t7xx: BUG: Unaligned access when loading mtk_t7xx module Message-ID: Precedence: bulk X-Mailing-List: netdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Disposition: inline Hello, I'm trying to use a Fibocom FM350-GL modem with a Quartzpro64 board based on RK3588 using Linus' tip of the tree and I'm getting a memory alignment fault when modprobe-ing the mtk_t7xx driver. The exception happens in t7xx_cldma_hw_set_start_addr() as the virtual address is not a 64bit address (ffff800085a1f00*4*). The same issue seems to have been found by openwrt people a few days ago: https://forum.openwrt.org/t/fibocom-fm350-gl-support/142682/67 Looking at the code I can see that the registers used for building the virtual address use the START_ADDRL (low) macro, which is wrong (that would be 32bit aligned, not 64bit). Except that .... /* CLDMA TX */ #define REG_CLDMA_UL_START_ADDRL_0 0x0004 #define REG_CLDMA_UL_START_ADDRH_0 0x0008 #define REG_CLDMA_UL_CURRENT_ADDRL_0 0x0044 #define REG_CLDMA_UL_CURRENT_ADDRH_0 0x0048 [....] #define REG_CLDMA_DL_START_ADDRL_0 0x0478 #define REG_CLDMA_DL_START_ADDRH_0 0x047c #define REG_CLDMA_DL_CURRENT_ADDRL_0 0x04b8 #define REG_CLDMA_DL_CURRENT_ADDRH_0 0x04bc There seems to be an unholy mess of register offsets. UL_START_ADDRL_0 is at a 32bit offset, but DL_START_ADDRL_0 is at a 64bit offset. UL_START_ADDRH_0 is at a 64bit offset, but DL_START_ADDRH_0 is not. Given that all accesses to those registers are io{read,write}64(), I question the need to have an High and Low register definition, so one of these can be removed and offsets corrected by someone with access to the documentation that gives correct information for the registers. I had a go at guessing that UL registers are at 0x8 and 0x48 offsets and DL registers are at 0x0478 and 0x04b8, but while that fixes the alignment exception, I now get a "CLDMA{0,1} queue 0 is not empty" message. For anyone trying to reproduce this: you first need to modify the device tree to slightly reduce the 3rd MEM area so that BAR0 of the root complex does not fit in and allocates all the available memory: --8<------------------------------------------------- --8<------------------------------------------------- After reboot, "dmesg | grep -i pci" gives: [ 0.000000] Kernel command line: earlycon=uart8250,mmio32,0xfeb50000 rootwait root=/dev/mmcblk0p2 rw pci=realloc=on [ 0.011344] PCI/MSI: /interrupt-controller@fe600000/msi-controller@fe640000 domain created [ 0.011388] PCI/MSI: /interrupt-controller@fe600000/msi-controller@fe660000 domain created [ 0.119664] PCI: CLS 0 bytes, default 64 [ 0.169966] pciehp: pcie_port_service_register = 0 [ 0.488618] rockchip-dw-pcie a40000000.pcie: host bridge /pcie@fe150000 ranges: [ 0.489346] rockchip-dw-pcie a40000000.pcie: Parsing ranges property...
