<herbert@gondor.apana.org.au> - -With recent kernels (>5.2), the driver fails to probe, as the -allocation of the driver's scatter buffer fails with -ENOMEM. - -This happens in crypto4xx_build_sdr(). Where the driver tries -to get 512KiB (=PPC4XX_SD_BUFFER_SIZE * PPC4XX_NUM_SD) of -continuous memory. This big chunk is by design, since the driver -uses this circumstance in the crypto4xx_copy_pkt_to_dst() to -its advantage: -"all scatter-buffers are all neatly organized in one big -continuous ringbuffer; So scatterwalk_map_and_copy() can be -instructed to copy a range of buffers in one go." - -The PowerPC arch does not have support for DMA_CMA. Hence, -this patch reorganizes the order in which the memory -allocations are done. Since the driver itself is responsible -for some of the issues. - -Signed-off-by: Christian Lamparter <chunkeey@gmail.com> ---- - drivers/crypto/amcc/crypto4xx_core.c | 27 +++++++++++++-------------- - 1 file changed, 13 insertions(+), 14 deletions(-) - ---- a/drivers/crypto/amcc/crypto4xx_core.c -+++ b/drivers/crypto/amcc/crypto4xx_core.c -@@ -286,7 +286,8 @@ static u32 crypto4xx_build_gdr(struct cr - - static inline void crypto4xx_destroy_gdr(struct crypto4xx_device *dev) - { -- dma_free_coherent(dev->core_dev->device, -+ if (dev->gdr) -+ dma_free_coherent(dev->core_dev->device, - sizeof(struct ce_gd) * PPC4XX_NUM_GD, - dev->gdr, dev->gdr_pa);
