2022-02-17drm/i915: fix build issue when using clangTong Zhang1-0/+1
drm/i915 adds some extra cflags, namely -Wall, which causes instances of -Wformat-security to appear when building with clang, even though this warning is turned off kernel-wide in the main Makefile: drivers/gpu/drm/i915/gt/intel_gt.c:983:2: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security] GEM_TRACE("ERROR\n"); ^~~~~~~~~~~~~~~~~~~~ ./drivers/gpu/drm/i915/i915_gem.h:76:24: note: expanded from macro 'GEM_TRACE' #define GEM_TRACE(...) trace_printk(__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~ ./include/linux/kernel.h:369:3: note: expanded from macro 'trace_printk' do_trace_printk(fmt, ##__VA_ARGS__); \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/linux/kernel.h:383:30: note: expanded from macro 'do_trace_printk' __trace_bprintk(_THIS_IP_, trace_printk_fmt, ##args); \ ^~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/gt/intel_gt.c:983:2: note: treat the string as an argument to avoid this This does not happen with GCC because it does not enable -Wformat-security with -Wall. Disable -Wformat-security within the i915 Makefile so that these warnings do not show up with clang.

IPS is a pretty well isolated feature. Move the relevant code to a separate file from polluting intel_display.c. I stuck to the hsw_ips name since that's what the function were already using, and also to avoid confusion with the ILK "Intelligen Power Sharing"/intel_ips GPU turbo stuff. And let's also do the s/dev_priv/i915/ rename while touching most of the code.

2021-12-01drm/i915: Update error capture code to avoid using the current vma stateThomas Hellström1-0/+1
With asynchronous migrations, the vma state may be several migrations ahead of the state that matches the request we're capturing. Address that by introducing an i915_vma_snapshot structure that can be used to snapshot relevant state at request submission. In order to make sure we access the correct memory, the snapshots take references on relevant sg-tables and memory regions. Also move the capture list allocation out of the fence signaling critical path and use the CONFIG_DRM_I915_CAPTURE_ERROR define to avoid compiling in members and functions used for error capture when they're not used. Finally, Introduce lockdep annotation. v4: - Break out the capture allocation mode change to a separate patch. v5: - Fix compilation error in the !CONFIG_DRM_I915_CAPTURE_ERROR case (kernel test robot) v6: - Use #if IS_ENABLED() instead of #ifdef to match driver style. - Move yet another change of allocation mode to the separate patch. - Commit message rework due to patch reordering. v7: - Adjust for removal of region refcounting.

The signaled bit is already used for quick testing if a fence is signaled. On top of that, it's a terrible abuse of dma-fence api, and in the common case where the object is already locked by the caller, the trylock will fail. If it were useful, the core dma-api would have exposed the same functionality. The fact that i915 has a dma_resv_utils.c file should be a warning that the functionality either belongs in core, or is not very useful at all. In this case the latter.

We are about to introduce failsafe- and asynchronous migration and ttm moves. This will add complexity and code to the TTM move code so it makes sense to split it out to a separate file to make the i915 TTM code easer to digest. Split the i915 TTM move code out and since we will have to change the name of the gpu_binds_iomem() and cpu_maps_iomem() functions anyway, we alter the name of gpu_binds_iomem() to i915_ttm_gtt_binds_lmem() which is more reflecting what it is used for. With this we also add some more documentation. Otherwise there should be no functional change.

2021-10-04drm/i915: Clean up disabled warningsNathan Chancellor1-6/+4
i915 enables a wider set of warnings with '-Wall -Wextra' then disables several with cc-disable-warning. If an unknown flag gets added to KBUILD_CFLAGS when building with clang, all subsequent calls to cc-{disable-warning,option} will fail, meaning that all of these warnings do not get disabled [1]. A separate series will address the root cause of the issue by not adding these flags when building with clang [2]; however, the symptom of these extra warnings appearing can be addressed separately by just removing the calls to cc-disable-warning, which makes the build ever so slightly faster because the compiler does not need to be called as much before building. The following warnings are supported by GCC 4.9 and clang 10.0.1, which are the minimum supported versions of these compilers so the call to cc-disable-warning is not necessary. Masahiro cleaned this up for the reset of the kernel in commit 4c8dd95a723d ("kbuild: add some extra warning flags unconditionally"). * -Wmissing-field-initializers * -Wsign-compare * -Wtype-limits * -Wunused-parameter -Wunused-but-set-variable was implemented in clang 13.0.0 and -Wframe-address was implemented in clang 12.0.0 so the cc-disable-warning calls are kept for these two warnings. Lastly, -Winitializer-overrides is clang's version of -Woverride-init, which is disabled for the specific files that are problematic. clang added a compatibility alias in clang 8.0.0 so -Winitializer-overrides can be removed.

2021-10-04drm/i915/pxp: Implement PXP irq handlerHuang, Sean Z1-0/+1
The HW will generate a teardown interrupt when session termination is required, which requires i915 to submit a terminating batch. Once the HW is done with the termination it will generate another interrupt, at which point it is safe to re-create the session. Since the termination and re-creation flow is something we want to trigger from the driver as well, use a common work function that can be called both from the irq handler and from the driver set-up flows, which has the addded benefit of allowing us to skip any extra locks because the work itself serializes the operations. v2: use struct completion instead of bool (Chris) v3: drop locks, clean up functions and improve comments (Chris), move to common work function. v4: improve comments, simplify wait logic (Rodrigo) v5: unconditionally set interrupts, rename state_attacked var (Rodrigo) v10: remove inclusion of intel_gt_types.h from intel_pxp.h (Jani) Signed-off-by: Alan Previn <alan.previn.teres.alexis@intel.com> Signed-off-by: Huang, Sean Z <sean.z.huang@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210924191452.1539378-10-alan.previn.teres.alexis@intel.com
