For other devices we either use # a sketchy bypass or hardware bypass but the former can only work if # the amount of RAM is no bigger than the device's DMA mask and the latter # requires devices to support at least 59bit DMA. # # This extends the default DMA window to the maximum size possible to allow # a wider DMA mask than just 32bit. The default window size is now limited # by the the iommu_table::it_map allocation bitmap which is a contiguous # array, 1 bit per an IOMMU page. # # This increases the default IOMMU page size from hard coded 4K to # the system page size to allow wider DMA masks. # # This increases the level number to not exceed the max order allocation # limit per TCE level. By the same time, this keeps minimal levels number # as 2 in order to save memory. # # As the extended window now overlaps the 32bit MMIO region, this adds # an area reservation to iommu_init_table(). # # After this change the default window size is 0x80000000000==1<<43 so # devices limited to DMA mask smaller than the amount of system RAM can # still use more than just 2GB of memory for DMA. # # This is an optimization and not a bug fix for DMA API usage. # # With the on-demand allocation of indirect TCE table levels enabled and # 2 levels, the first TCE level size is just # 1<<ceil((log2(0x7ffffffffff+1)-16)/2)=16384 TCEs or 2 system pages. # # Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190718051139.74787-5-aik@ozlabs.ru # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 f74fc58f295a45c29b565a898d869034099ca9a1 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # Added to kconfig CONFIG_PPC_RADIX_MMU=n # yes \n | make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powernv_defconfig+NO_RADIX_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/drivers/scsi/cxlflash/main.c: In function 'send_afu_cmd': /kisskb/src/drivers/scsi/cxlflash/main.c:2347:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (rc) { ^ /kisskb/src/drivers/scsi/cxlflash/main.c:2357:2: note: here case -EAGAIN: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c: In function 'term_intr': /kisskb/src/drivers/scsi/cxlflash/main.c:754:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (index == PRIMARY_HWQ) ^ /kisskb/src/drivers/scsi/cxlflash/main.c:756:2: note: here case UNMAP_TWO: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:757:3: warning: this statement may fall through [-Wimplicit-fallthrough=] cfg->ops->unmap_afu_irq(hwq->ctx_cookie, 2, hwq); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:758:2: note: here case UNMAP_ONE: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:759:3: warning: this statement may fall through [-Wimplicit-fallthrough=] cfg->ops->unmap_afu_irq(hwq->ctx_cookie, 1, hwq); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:760:2: note: here case FREE_IRQ: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c: In function 'cxlflash_remove': /kisskb/src/drivers/scsi/cxlflash/main.c:975:3: warning: this statement may fall through [-Wimplicit-fallthrough=] cxlflash_release_chrdev(cfg); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:976:2: note: here case INIT_STATE_SCSI: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:978:3: warning: this statement may fall through [-Wimplicit-fallthrough=] scsi_remove_host(cfg->host); ^~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:979:2: note: here case INIT_STATE_AFU: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:980:3: warning: this statement may fall through [-Wimplicit-fallthrough=] term_afu(cfg); ^~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:981:2: note: here case INIT_STATE_PCI: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:983:3: warning: this statement may fall through [-Wimplicit-fallthrough=] pci_disable_device(pdev); ^~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/drivers/scsi/cxlflash/main.c:984:2: note: here case INIT_STATE_NONE: ^~~~ /kisskb/src/drivers/scsi/cxlflash/main.c: In function 'num_hwqs_store': /kisskb/src/drivers/scsi/cxlflash/main.c:3018:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (cfg->state == STATE_NORMAL) ^ /kisskb/src/drivers/scsi/cxlflash/main.c:3020:2: note: here default: ^~~~~~~ WARNING: vmlinux.o(.text+0x2bd0): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel() The function start_here_common() references the function __init start_kernel().
