For the overview. dma-buf today only have debugfs for info. Debugfs is not allowed by google to use in andoid. So this aggregate the information so we can get information on what going on on the system. And the LKML standard respond to that is "SHOW ME THE CODE". When the top memgc has a aggregated information on dma-buf it is maybe a better source to meminfo. But then it also imply that dma-buf requires memcg. And I dont see any problem to replace this with something better with it is ready. > -Daniel > >> --- >> drivers/dma-buf/dma-buf.c | 12 ++++++++++++ >> fs/proc/meminfo.c | 5 ++++- >> include/linux/dma-buf.h | 1 + >> 3 files changed, 17 insertions(+), 1 deletion(-) >> >> diff --git a/drivers/dma-buf/dma-buf.c b/drivers/dma-buf/dma-buf.c >> index f264b70c383e..4dc37cd4293b 100644 >> --- a/drivers/dma-buf/dma-buf.c >> +++ b/drivers/dma-buf/dma-buf.c >> @@ -37,6 +37,7 @@ struct dma_buf_list { >> }; >> >> static struct dma_buf_list db_list; >> +static atomic_long_t dma_buf_global_allocated; >> >> static char *dmabuffs_dname(struct dentry *dentry, char *buffer, int buflen) >> { >> @@ -79,6 +80,7 @@ static void dma_buf_release(struct dentry *dentry) >> if (dmabuf->resv == (struct dma_resv *)&dmabuf[1]) >> dma_resv_fini(dmabuf->resv); >> >> + atomic_long_sub(dmabuf->size, &dma_buf_global_allocated); >> module_put(dmabuf->owner); >> kfree(dmabuf->name); >> kfree(dmabuf); >> @@ -586,6 +588,7 @@ struct dma_buf *dma_buf_export(const struct dma_buf_export_info *exp_info) >> mutex_lock(&db_list.lock); >> list_add(&dmabuf->list_node, &db_list.head); >> mutex_unlock(&db_list.lock); >> + atomic_long_add(dmabuf->size, &dma_buf_global_allocated); >> >> return dmabuf; >> >> @@ -1346,6 +1349,15 @@ void dma_buf_vunmap(struct dma_buf *dmabuf, struct dma_buf_map *map) >> } >> EXPORT_SYMBOL_GPL(dma_buf_vunmap); >> >> +/** >> + * dma_buf_allocated_pages - Return the used nr of pages >> + * allocated for dma-buf >> + */ >> +long dma_buf_allocated_pages(void) >> +{ >> + return atomic_long_read(&dma_buf_global_allocated) >> PAGE_SHIFT; >> +} >> + >> #ifdef CONFIG_DEBUG_FS >> static int dma_buf_debug_show(struct seq_file *s, void *unused) >> { >> diff --git a/fs/proc/meminfo.c b/fs/proc/meminfo.c >> index 6fa761c9cc78..ccc7c40c8db7 100644 >> --- a/fs/proc/meminfo.c >> +++ b/fs/proc/meminfo.c >> @@ -16,6 +16,7 @@ >> #ifdef CONFIG_CMA >> #include <linux/cma.h> >> #endif >> +#include <linux/dma-buf.h> >> #include <asm/page.h> >> #include "internal.h" >> >> @@ -145,7 +146,9 @@ static int meminfo_proc_show(struct seq_file *m, void *v) >> show_val_kb(m, "CmaFree: ", >> global_zone_page_state(NR_FREE_CMA_PAGES)); >> #endif >> - >> +#ifdef CONFIG_DMA_SHARED_BUFFER >> + show_val_kb(m, "DmaBufTotal: ", dma_buf_allocated_pages()); >> +#endif >> hugetlb_report_meminfo(m); >> >> arch_report_meminfo(m); >> diff --git a/include/linux/dma-buf.h b/include/linux/dma-buf.h >> index efdc56b9d95f..5b05816bd2cd 100644 >> --- a/include/linux/dma-buf.h >> +++ b/include/linux/dma-buf.h >> @@ -507,4 +507,5 @@ int dma_buf_mmap(struct dma_buf *, struct vm_area_struct *, >> unsigned long); >> int dma_buf_vmap(struct dma_buf *dmabuf, struct dma_buf_map *map); >> void dma_buf_vunmap(struct dma_buf *dmabuf, struct dma_buf_map *map); >> +long dma_buf_allocated_pages(void); >> #endif /* __DMA_BUF_H__ */ >> -- >> 2.17.1 >> >> _______________________________________________ >> dri-devel mailing list >> dri-devel@lists.freedesktop.org >> https://urldefense.com/v3/__https://lists.freedesktop.org/mailman/listinfo/dri-devel__;!!JmoZiZGBv3RvKRSx!qW8kUOZyY4Dkew6OvqgfoM-5unQNVeF_M1biaIAyQQBR0KB7ksRzZjoh382ZdGGQR9k$

Well, the problem with replacing the counter in /proc/meminfo is that it requires all users of /proc/meminfo to adapt to the changes. That's why it's way less painful to go an extra mile and define (hopefully) stable user ABI up front. Why can't you use fdinfo to show how much memory consumed by a dma-buf? > > -Daniel > > > >> --- > >> drivers/dma-buf/dma-buf.c | 12 ++++++++++++ > >> fs/proc/meminfo.c | 5 ++++- > >> include/linux/dma-buf.h | 1 + > >> 3 files changed, 17 insertions(+), 1 deletion(-) > >> > >> diff --git a/drivers/dma-buf/dma-buf.c b/drivers/dma-buf/dma-buf.c > >> index f264b70c383e..4dc37cd4293b 100644 > >> --- a/drivers/dma-buf/dma-buf.c > >> +++ b/drivers/dma-buf/dma-buf.c > >> @@ -37,6 +37,7 @@ struct dma_buf_list { > >> }; > >> > >> static struct dma_buf_list db_list; > >> +static atomic_long_t dma_buf_global_allocated; > >> > >> static char *dmabuffs_dname(struct dentry *dentry, char *buffer, int buflen) > >> { > >> @@ -79,6 +80,7 @@ static void dma_buf_release(struct dentry *dentry) > >> if (dmabuf->resv == (struct dma_resv *)&dmabuf[1]) > >> dma_resv_fini(dmabuf->resv); > >> > >> + atomic_long_sub(dmabuf->size, &dma_buf_global_allocated); > >> module_put(dmabuf->owner); > >> kfree(dmabuf->name); > >> kfree(dmabuf); > >> @@ -586,6 +588,7 @@ struct dma_buf *dma_buf_export(const struct dma_buf_export_info *exp_info) > >> mutex_lock(&db_list.lock); > >> list_add(&dmabuf->list_node, &db_list.head); > >> mutex_unlock(&db_list.lock); > >> + atomic_long_add(dmabuf->size, &dma_buf_global_allocated); > >> > >> return dmabuf; > >> > >> @@ -1346,6 +1349,15 @@ void dma_buf_vunmap(struct dma_buf *dmabuf, struct dma_buf_map *map) > >> } > >> EXPORT_SYMBOL_GPL(dma_buf_vunmap); > >> > >> +/** > >> + * dma_buf_allocated_pages - Return the used nr of pages > >> + * allocated for dma-buf > >> + */ > >> +long dma_buf_allocated_pages(void) > >> +{ > >> + return atomic_long_read(&dma_buf_global_allocated) >> PAGE_SHIFT; > >> +} > >> + > >> #ifdef CONFIG_DEBUG_FS > >> static int dma_buf_debug_show(struct seq_file *s, void *unused) > >> { > >> diff --git a/fs/proc/meminfo.c b/fs/proc/meminfo.c > >> index 6fa761c9cc78..ccc7c40c8db7 100644 > >> --- a/fs/proc/meminfo.c > >> +++ b/fs/proc/meminfo.c > >> @@ -16,6 +16,7 @@ > >> #ifdef CONFIG_CMA > >> #include <linux/cma.h> > >> #endif > >> +#include <linux/dma-buf.h> > >> #include <asm/page.h> > >> #include "internal.h" > >> > >> @@ -145,7 +146,9 @@ static int meminfo_proc_show(struct seq_file *m, void *v) > >> show_val_kb(m, "CmaFree: ", > >> global_zone_page_state(NR_FREE_CMA_PAGES)); > >> #endif > >> - > >> +#ifdef CONFIG_DMA_SHARED_BUFFER > >> + show_val_kb(m, "DmaBufTotal: ", dma_buf_allocated_pages()); > >> +#endif > >> hugetlb_report_meminfo(m); > >> > >> arch_report_meminfo(m); > >> diff --git a/include/linux/dma-buf.h b/include/linux/dma-buf.h > >> index efdc56b9d95f..5b05816bd2cd 100644 > >> --- a/include/linux/dma-buf.h > >> +++ b/include/linux/dma-buf.h > >> @@ -507,4 +507,5 @@ int dma_buf_mmap(struct dma_buf *, struct vm_area_struct *, > >> unsigned long); > >> int dma_buf_vmap(struct dma_buf *dmabuf, struct dma_buf_map *map); > >> void dma_buf_vunmap(struct dma_buf *dmabuf, struct dma_buf_map *map); > >> +long dma_buf_allocated_pages(void); > >> #endif /* __DMA_BUF_H__ */ > >> -- > >> 2.17.1 > >> > >> _______________________________________________ > >> dri-devel mailing list > >> dri-devel@lists.freedesktop.org > >> https://urldefense.com/v3/__https://lists.freedesktop.org/mailman/listinfo/dri-devel__;!!JmoZiZGBv3RvKRSx!qW8kUOZyY4Dkew6OvqgfoM-5unQNVeF_M1biaIAyQQBR0KB7ksRzZjoh382ZdGGQR9k$ > -- Sincerely yours, Mike.

This is on a idle system. Im not sure why you need it.The problem is partly that debugfs is not accessable on a commercial device.

If the newer implementations is not get the same result it is not doing it right and is not better. If a memcg counter or a global_zone counter do the same thing they it can replace the suggested method. But I dont think they will. dma-buf does not have to be mapped to a process, and the case of vram, it is not covered in current global_zone. All of them would be very nice to have in some form.

I strongly suspect that the main problem of this patch (and its previous versions) is that you are failing to explain the purpose of the counter to others. From what you have said so far it sounds like this is a number which is nice to have because gives us more than nothing. And while this is not really hard to agree with it doesn't really meet the justification for exporting yet another counter to the userspace with all the headache of the future maintenance. I think it would hugely help to describe a typical scenario when the counter would be useful and the conclusion you can draw from the exported value or a set of values over time. And please note that a mixed bag of different memory resources in a single counter doesn't make this any easier because then it essentially makes it impossible to know whether an excessive usage contribues to RAM or device memory depletion - hence this is completely bogus for the OOM report. -- Michal Hocko SUSE Labs

To clarify the GL texture example: a GL texture consumes "graphics memory", whatever that is, but they are not allocated as dmabufs. So they count for resource consumption, but they do not show up in your counter, until they become exported. Most GL textures are never exported at all. In fact, exporting GL textures is a path strongly recommended against due to unsuitable EGL/GL API. As far as I understand, dmabufs are never allocated as is. Dmabufs always just wrap an existing memory allocation. So creating (exporting) a dmabuf does not increase resource usage. Allocation increases resource usage, and most allocations are never exported. > If there is a limitation on your pointers it is a good metric to count them > even if you don't know what they are. Same goes for dma-buf, they > are generic, but they consume some resources that are counted in pages. Given above, I could even argue that *dmabufs* do not consume resources. They only reference resources that were already allocated by some specific means (not generic). They might keep the resource allocated, preventing it from being freed if leaked. As you might know, there is no really generic "dmabuf allocator", not as a kernel UAPI nor as a userspace library (the hypothetical Unix Device Memory Allocator library notwithstanding). So this kind of leaves the question, what is DmaBufTotal good for? Is it the same kind of counter as VIRT in 'top'? If you know your particular programs, you can maybe infer if VIRT is too much or not, but for e.g. WebKitWebProcess it is normal to have 85 GB in VIRT and it's not a problem (like I have, on this 8 GB RAM machine).

Let me try to summarize my understanding of the problem, maybe it'll help others as well. A device driver allocates memory and exports this memory via dma-buf so that this memory will be accessible for userspace via a file descriptor. The allocated memory can be either allocated with alloc_page() from system RAM or by other means from dedicated VRAM (that is not managed by Linux mm) or even from on-device memory. The dma-buf driver tracks the amount of the memory it was requested to export and the size it sees is available at debugfs and fdinfo. The debugfs is not available to user and maybe entirely disabled in production systems. There could be quite a few open dma-bufs so there is no overall summary, plus fdinfo in production systems your refer to is also unavailable to the user because of selinux policy. And there are a few details that are not clear to me: * Since DRM device drivers seem to be the major user of dma-buf exports, why cannot we add information about their memory consumption to, say, /sys/class/graphics/drm/cardX/memory-usage? * How exactly user generates reports that would include the new counters? From my (mostly outdated) experience Android users won't open a terminal and type 'cat /proc/meminfo' there. I'd presume there is a vendor agent that collects the data and sends it for analysis. In this case what is the reason the vendor is unable to adjust selinix policy so that the agent will be able to access fdinfo? * And, as others already mentioned, it is not clear what are the problems that can be detected by examining DmaBufTotal except saying "oh, there is too much/too little memory exported via dma-buf". What would be user visible effects of these problems? What are the next steps to investigate them? What other data will be probably required to identify root cause? -- Sincerely yours, Mike.

So the flow is like this: * a user has a problem and reports it to an application developer; at best the user runs simple and limited app to collect some data * if the application developer considers this issue as a system related they can open adb and collect some more information about the system using non-root shell with selinux policy restrictions and send this information to the device manufacturer. * the manufacturer continues to debug the issue and at this point as much information is possible would have been useful. In this flow I still fail to understand why the manufacturer cannot provide userspace tools that will be able to collect the required information. These tools not necessarily need to target the end user, they may be only intended for the application developers, e.g. policy could allow such tool to access some of the system data only when the system is in developer mode. -- Sincerely yours, Mike.

This is what the patch is about. Even for a application developer a commercial phone is locked down. Many vendors allow that you flash some other software like a AOSP. But that can be very different. Like installing a ubuntu on a PC to debug a Fedora issue. And sure we can pickup parts of what using the dma-buf. But we can not get the total and be sure that is the total without a proper counter.

So there could be some tools that are only available in the developer mode? These tools could have different permissions etc. > Many vendors allow that you flash some other software like a AOSP.

If I understand you correctly, a user space tool that scans fdinfo and accumulates dma-buf size from there is not accurate enough, that's why an atomic counter exposed by kernel is a must. But if the changes in consumption of dma-bufs are that frequent, I cannot see how a global counter will help to identify an issue. And if this counter is needed to see if there is a memory leak, summing sizes of dma-bufs from fdinfo will identify a leak. What am I missing?

No. There is a lot of restrictions, and Google will provide a binary kernel that is used on android devices that is the one hat MUST be used on commercial models. It is called GKI. > So there could be some tools that are only available in the developer mode? > These tools could have different permissions etc. > >> Many vendors allow that you flash some other software like a AOSP.

And it is lightweight. > But if the changes in consumption of dma-bufs are that frequent, I cannot > see how a global counter will help to identify an issue. Same goes for all memory counters. You can sample the counters and build statistics when you have many devices. Statistics change you usually see leaks. > And if this counter is needed to see if there is a memory leak, summing > sizes of dma-bufs from fdinfo will identify a leak. > > What am I missing? > I think you can only see dma-buf that is mapped to a process with that method, we have buffers that goes to other subsystems like audiodsp. And processing all fd's on a system frequently and sort out all duplicates is not light, and it sill will not be a total. Nor is it a snapshot. When it is about to find the leaks, kmemleak works fine with kernel leaks, and page_owner (also only in debugfs) is a good tool.

This adds a total used dma-buf memory. Details can be found in debugfs, however it is not for everyone and not always available. dma-buf are indirect allocated by userspace. So with this value we can monitor and detect userspace applications that have problems.
