| Description | Bits,Field,Recommended setting,Description [31],xdma_drain_dat_en,1b1,XDMA set to 0x1. Enable draining of dat when run bit is not set for xdma. [30],xdma_drain_dsc_en,1b1,XDMA set to 0x1. Enable draining of dsc when run bit is not set for xdma. [29:28],Reserved,1h0,Reserved [27:16],brdg_slv_wr_pasid_offset[11:0],12h0,Pasid index offset for bridge slave write requests if shared_rdwr_pasid_dis is set [15],brdg_slv_shared_rdwr_pasid_dis,1h0,Enable different pasid for rd and writes from bridge slave. [14],Reserved,1h0,Reserved [13],axi_parity_chk_dis,1h0,Disable AXI slave parity checks [12:5],slv_fnc_msk[7:0],8h0,Mask for function bits received by aximm slave. Useful if number of functions supported needs less than 8 bits. Upper bits can then be used for SMID [4],Reserved,1h0,Reserved [3],fabric_reset_en,1b1,Enable reset from fabric [2],rrq_disable_en,1h0,Block new read requests on RQ timeout or register write [1],Reserved,1h0,Reserved [0],brdg_slv_pasid_offset[11],1h0,Pasid index offset[11] for bridge slave requests. Pasid index offset[10:0] is defined in the attr_dma_spare_1_l attribute register. |
This register should only be written to during reset of the PCIe block Alternate register name: attr_dma_spare_1_h
