guc_mmio_regset_write() had a flags for the registers to be added to the GuC's regset list. The only register actually using that was RCU_MODE, but it was setting the flags to a bogus value. From struct xe_guc_fwif.h, #define GUC_REGSET_MASKED BIT(0) #define GUC_REGSET_MASKED_WITH_VALUE BIT(2) #define GUC_REGSET_RESTORE_ONLY BIT(3) Cross checking with i915, the only flag to set in RCU_MODE is GUC_REGSET_MASKED. That can be done automatically from the register, as long as the definition is correct. Add the XE_REG_OPTION_MASKED annotation to RCU_MODE and kill the "flags" field in guc_mmio_regset_write(): guc_mmio_regset_write_one() can decide that based on the register being passed.

On i915 the "see comment about Wa_22013088509" referred to the comment in the graphics version >= 11 branch, where there were more details about it. From the platforms supported by xe, only PVC needs Wa_22013088509, but as the comment says, it's simpler to do it for all platforms as there is no downside. Bring the missing comment over from i915 and reword it to fit xe better.

Reading the GMD_ID register on platforms before that register became available is not reliable. The assumption was that since the register was not allocated, it would return 0. But on PVC for example it returns garbage (or a very specific number), triggering the following error: xe 0000:8c:00.0: [drm] *ERROR* Hardware reports unknown media version 1025.55 Fix it by stop relying on the value returned by that registers on platforms before GMD_ID. Instead this relies on the graphics description struct being already pre-set on the device: this can only ever be true for platforms before the GMD_ID support. In that case, GMD_ID is skipped and the hardcoded values are used. This should also help on early bring-up in case the GMD_ID returns something not expected and we need to temporarily hardcode values. With this, PVC doesn't trigger the error and goes straight to: xe 0000:8c:00.0: [drm:xe_display_info_init [xe]] No display IP, skipping xe 0000:8c:00.0: [drm:xe_pci_probe [xe]] XE_PVC 0bd5:002f dgfx:1 gfx:Xe_HPC (12.60) media:none (0.00) dma_m_s:52 tc:2 xe 0000:8c:00.0: [drm:xe_pci_probe [xe]] Stepping = (G:C0, M:**, D:**, B:B3) Fixes: 5822bba9 ("drm/xe: Select graphics/media descriptors from GMD_ID") Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Link: https://lore.kernel.org/r/20230427184408.1340988-1-lucas.demarchi@intel.comSigned-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

Now that struct xe_reg and struct xe_reg_mcr are types that can be used by xe, convert more of the driver to use them. Some notes about the conversions: - The RTP tables don't need the MASKED flags anymore in the actions as that information now comes from the register definition - There is no need for the _XE_RTP_REG/_XE_RTP_REG_MCR macros and the register types on RTP infra: that comes from the register definitions. - When declaring the RTP entries, there is no need anymore to undef XE_REG and friends: the RTP macros deal with removing the cast where needed due to not being able to use a compound statement for initialization in the tables - The index in the reg-sr xarray is the register offset only. Otherwise we wouldn't catch mistakes about adding both a MCR-style and normal-style registers. For that, the register is now also part of the entry, so the options can be compared to check for compatible entries. In order to be able to accomplish this, some improvements are needed on the RTP macros. Change its implementation to concentrate on "pasting a prefix to each argument" rather than the more general "call any macro for each argument". Hopefully this will avoid trying to extend this infra and making it more complex. With the use of tuples for building the arguments, it's not possible to pass additional register fields and using xe_reg in the RTP tables. xe_mmio_* still need to be converted, from u32 to xe_reg, but that is left for another change.

These should replace the _MMIO() and MCR_REG() from i915, with the goal of being more extensible, allowing to pass the additional fields for struct xe_reg and struct xe_reg_mcr. Replace all uses of _MMIO() and MCR_REG() in xe. Since the RTP, reg-save-restore and WA infra are not ready to use the new type, just undef the macro like was done for the i915 types previously.

Stop using i915 types for registers. Use our own types. Differently from i915, this will keep under the register definition the knowledge for the different types of registers. For now, the "flags"/"options" are mcr and masked, although only the former is being used. Additionally MCR registers have their own type. The only place that should really look inside a xe_mcr_reg_t is that code dealing with the steering and using other APIs when the register is MCR has been a source of problem in the past. Most of the driver is agnostic to the register differences since they either use the definition from the header or already call the correct MCR_REG()/_MMIO() macros. By embeding the struct xe_reg inside the struct it's also possible to guarantee the compiler will break if using RANDOM_MCR_REG.reg is attempted, since now the u32 is inside the inner struct. v2: - Deep a dedicated type for MCR registers to avoid misuse (Matt Roper, Jani) - Drop the typedef and just use a struct since it's not an opaque type (Jani) - Add more kernel-doc v3: - Use only 22 bits for the register address since all the platforms supported so far have only 4MB of MMIO per tile (Matt Roper) Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://lore.kernel.org/r/20230427223256.1432787-7-lucas.demarchi@intel.comSigned-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
