Negative constant left-shift is undefined behaviour in the C standard, and as such newer versions of clang (at least) warn against it. GCC supports it for a long time, but it would be better to remove it and rely on defined behaviour. My understanding is "~(-1 << N)" in 2's complement is intended to generate a bit pattern of zeroes ending with N '1' bits. The same can be achieved by "(1 << N) - 1" in a well-defined way, so switch to it to remove the warning. Tested: building a kernel with generic SCSI tape, and checking basic operations (mt status, mt eject) on a real LTO unit. Cannot test the osst driver. Signed-off-by:

Add this functionality, placing the descriptor being read in the actual data buffer in the bio. That is, for both read and write descriptors query upiu, we are using the job's request_payload. This in turn, is mapped back in user land to the applicable sg_io_v4 xferp: dout_xferp for write descriptor, and din_xferp for read descriptor. Signed-off-by:

Allow to read descriptors via raw upiu. This in fact was forbidden just as a precaution, as ufs-bsg actually enforces which functionality is supported. Signed-off-by:

Avri Altman authored
When we had a write descriptor query upiu, we appended the descriptor right after the bsg request. This was fine as the bsg driver allows to allocate whatever buffer we needed in its job request. Still, the proper way to deliver payload, however small (we only write config descriptors of 144 bytes), is by using the job request payload data buffer. So change this ABI now, while ufs-bsg is still new, and nobody is actually using it. Signed-off-by:

This reverts commit 60f01870. There was one conflict in drivers/scsi/ufs/ufshcd.c <<<<<<< HEAD /* Init check for device descriptor sizes */ ufshcd_init_desc_sizes(hba); ret = ufs_get_device_desc(hba, &card); if (ret) { dev_err(hba->dev, "%s: Failed getting device info. err = %d\n", __func__, ret); goto out; } ufs_fixup_device_setup(hba, &card); ufshcd_tune_unipro_params(hba); ret = ufshcd_set_vccq_rail_unused(hba, (hba->dev_quirks & UFS_DEVICE_NO_VCCQ) ? true : false); if (ret) goto out; ======= ufs_advertise_fixup_device(hba); >>>>>>> parent of 60f01870... scsi: ufs: disable vccq if it's not needed by UFS device Resolution: keep HEAD, and delete the ufshcd_set_vccq_rail_unused() call and corresponding error-handling code. Clean up loose ends in a follow-up patch. 60f01870 introduced a small power optimization: ignore the vccq load specified in the UFSHC DT node when said host controller is connected to specific Flash chips (currently, Samsung and Hynix). Unfortunately, this optimization breaks UFS on systems where vccq powers not only the Flash chip, but the host controller as well, such as APQ8098 MEDIABOX or MTP8998: [ 3.929877] ufshcd-qcom 1da4000.ufshc: ufshcd_query_attr: opcode 0x04 for idn 13 failed, index 0, err = -11 [ 5.433815] ufshcd-qcom 1da4000.ufshc: ufshcd_query_attr: opcode 0x04 for idn 13 failed, index 0, err = -11 [ 6.937771] ufshcd-qcom 1da4000.ufshc: ufshcd_query_attr: opcode 0x04 for idn 13 failed, index 0, err = -11 [ 6.937866] ufshcd-qcom 1da4000.ufshc: ufshcd_query_attr_retry: query attribute, idn 13, failed with error -11 after 3 retires [ 6.946412] ufshcd-qcom 1da4000.ufshc: ufshcd_disable_auto_bkops: failed to enable exception event -11 [ 6.957972] ufshcd-qcom 1da4000.ufshc: dme-peer-get: attr-id 0x1587 failed 3 retries [ 6.967181] ufshcd-qcom 1da4000.ufshc: dme-peer-get: attr-id 0x1586 failed 3 retries [ 6.975025] ufshcd-qcom 1da4000.ufshc: ufshcd_get_max_pwr_mode: invalid max pwm tx gear read = 0 [ 6.982755] ufshcd-qcom 1da4000.ufshc: ufshcd_probe_hba: Failed getting max supported power mode [ 8.505770] ufshcd-qcom 1da4000.ufshc: ufshcd_query_flag: Sending flag query for idn 3 failed, err = -11 [ 10.009807] ufshcd-qcom 1da4000.ufshc: ufshcd_query_flag: Sending flag query for idn 3 failed, err = -11 [ 11.513766] ufshcd-qcom 1da4000.ufshc: ufshcd_query_flag: Sending flag query for idn 3 failed, err = -11 [ 11.513861] ufshcd-qcom 1da4000.ufshc: ufshcd_query_flag_retry: query attribute, opcode 5, idn 3, failed with error -11 after 3 retires [ 13.049807] ufshcd-qcom 1da4000.ufshc: __ufshcd_query_descriptor: opcode 0x01 for idn 8 failed, index 0, err = -11 [ 14.553768] ufshcd-qcom 1da4000.ufshc: __ufshcd_query_descriptor: opcode 0x01 for idn 8 failed, index 0, err = -11 [ 16.057767] ufshcd-qcom 1da4000.ufshc: __ufshcd_query_descriptor: opcode 0x01 for idn 8 failed, index 0, err = -11 [ 16.057872] ufshcd-qcom 1da4000.ufshc: ufshcd_read_desc_param: Failed reading descriptor. desc_id 8, desc_index 0, param_offset 0, ret -11 [ 16.067109] ufshcd-qcom 1da4000.ufshc: ufshcd_init_icc_levels: Failed reading power descriptor.len = 98 ret = -11 [ 37.073787] ufshcd-qcom 1da4000.ufshc: link startup failed 1 In my opinion, the rationale for the original patch is questionable. If neither the UFSHC, nor the Flash chip, require any load from vccq, then that power rail should simply not be specified at all in the DT. Working around that fact in the driver is detrimental, as evidenced by the failure to initialize the host controller on MSM8998. Acked-by:

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of 0xFFFF blocks. That looks bogus, especially for a device with a 4096-byte physical block size. Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's reported physical block size. To make the sanity checking conditionals more readable--and to facilitate printing warnings--relocate the checking to a helper function. No functional change aside from the printks.

commit 1917d42d ("fcoe: use enum for fip_mode") introduces a separate enum for the fip_mode that shall be used during initialisation handling until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That change was incomplete and gcc quietly converted in various places between the fip_mode and the fip_state enum values with implicit enum conversions, which fortunately cannot cause any issues in the actual code's execution. clang however warns about these implicit enum conversions in the scsi drivers. This commit consolidates the use of the two enums, guided by clang's enum-conversion warnings. This commit now completes the use of the fip_mode: It expects and uses fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to indicate these two enums are distinct.
