Hi Marc, I hit some hard problem on the pcie backporting to 3.18. I tried to pick up pcie related change to 3.18 kernel, the result is here: git://git.linaro.org/kernel/linux-linaro-stable.git v3.18/topic/pcie/master but it failed to setup juno r1 pcie port: ===== pci 0000:00:00.0: reg 0x10: [mem 0x57c00000-0x57c03fff 64bit pref] ... pcieport 0000:00:00.0: can't enable device: BAR 0 [mem 0x57c00000-0x57c03fff 64bit pref] not claimed pcieport: probe of 0000:00:00.0 failed with error -22 ===== The full pcie.txt log is attached. I also tried to seek some clues from 3.18/4.1 commits comparing, as following command. but failed on leaking related experience. The 4.1 kernel with pcie backport works good. $git log --oneline v3.18.24.. --cherry-mark --right-only 3.18/pcie/master...origin/v4.1/topic/pcie-junor1 &> full-4.1.diff.commits Could you like to give me some comments here? How to do the debug or what I missed? Thanks a lot! Alex

[PATCH V4] PM / OPP: Add debugfs support

by Viresh Kumar

This patch adds debugfs support to OPP layer to export OPPs and their properties for all the devices. This creates a top level directory: /sys/kernel/debug/opp and then device specific directories (based on device names) inside it. For example: 'cpu0', 'cpu1', etc.. If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory. Inside the device specific directory, a separate directory is created for each OPP. And within that files per opp property. Signed-off-by: Viresh Kumar <viresh.kumar(a)linaro.org> --- Hi Rafael, This was applied to pm/linux-next earlier, but then we dropped it citing few merge conflicts with driver-core changes. i.e. debugfs_create_bool() and debugfs_create_ulong() changes. All that is merged by Linus and so we can get this merged back again, once you are comfortable. @Stephen: I have dropped your Reviewed by tag as there were minor changes here, please give it again :) V3->V4: - debugfs_create_bool() takes boolean now, no need to typecast. - debugfs_create_ulong() is present now, use it. - Add another debugfs file to show if OPP is suspend-opp or not. drivers/base/power/opp/Makefile | 1 + drivers/base/power/opp/core.c | 21 +++- drivers/base/power/opp/debugfs.c | 216 +++++++++++++++++++++++++++++++++++++++ drivers/base/power/opp/opp.h | 44 ++++++++ 4 files changed, 280 insertions(+), 2 deletions(-) create mode 100644 drivers/base/power/opp/debugfs.c diff --git a/drivers/base/power/opp/Makefile b/drivers/base/power/opp/Makefile index 33c1e18c41a4..19837ef04d8e 100644 --- a/drivers/base/power/opp/Makefile +++ b/drivers/base/power/opp/Makefile @@ -1,2 +1,3 @@ ccflags-$(CONFIG_DEBUG_DRIVER) := -DDEBUG obj-y += core.o cpu.o +obj-$(CONFIG_DEBUG_FS) += debugfs.o diff --git a/drivers/base/power/opp/core.c b/drivers/base/power/opp/core.c index d5c1149ff123..9311f4c79ad2 100644 --- a/drivers/base/power/opp/core.c +++ b/drivers/base/power/opp/core.c @@ -457,6 +457,7 @@ static void _kfree_list_dev_rcu(struct rcu_head *head) static void _remove_list_dev(struct device_list_opp *list_dev, struct device_opp *dev_opp) { + opp_debug_unregister(list_dev, dev_opp);

[PATCH] arm64: bpf: fix JIT stack setup

by Yang Shi

ARM64 JIT used FP (x29) as eBPF fp register, but FP is subjected to change during function call so it may cause the BPF prog stack base address change too. Whenever, it pointed to the bottom of BPF prog stack instead of the top. So, when copying data via bpf_probe_read, it will be copied to (SP - offset), then it may overwrite the saved FP/LR. Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee saved register, so it will keep intact during function call. It is initialized in BPF prog prologue when BPF prog is started to run everytime. When BPF prog exits, it could be just tossed. Other than this the BPf prog stack base need to be setup before function call stack. So, the BPF stack layout looks like: high original A64_SP => 0:+-----+ BPF prologue | | FP/LR and callee saved registers BPF fp register => +64:+-----+ | | | ... | BPF prog stack | | | | current A64_SP => +-----+ | | | ... | Function call stack | | +-----+ low Signed-off-by: Yang Shi <yang.shi(a)linaro.org> CC: Zi Shen Lim <zlim.lnx(a)gmail.com> CC: Xi Wang <xi.wang(a)gmail.com> --- arch/arm64/net/bpf_jit_comp.c | 38 +++++++++++++++++++++++++++++++------- 1 file changed, 31 insertions(+), 7 deletions(-) diff --git a/arch/arm64/net/bpf_jit_comp.c b/arch/arm64/net/bpf_jit_comp.c index a44e529..6809647 100644 --- a/arch/arm64/net/bpf_jit_comp.c +++ b/arch/arm64/net/bpf_jit_comp.c @@ -50,7 +50,7 @@ static const int bpf2a64[] = { [BPF_REG_8] = A64_R(21), [BPF_REG_9] = A64_R(22), /* read-only frame pointer to access stack */ - [BPF_REG_FP] = A64_FP, + [BPF_REG_FP] = A64_R(25), /* temporary register for internal BPF JIT */ [TMP_REG_1] = A64_R(23), [TMP_REG_2] = A64_R(24), @@ -155,18 +155,42 @@ static void build_prologue(struct jit_ctx *ctx) stack_size += 4; /* extra for skb_copy_bits buffer */ stack_size = STACK_ALIGN(stack_size); + /* + * BPF prog stack layout + * + * high + * original A64_SP => 0:+-----+ BPF prologue + * | | FP/LR and callee saved registers + * BPF fp register => +64:+-----+ + * | | + * | ... | BPF prog stack + * | | + * | | + * current A64_SP => +-----+ + * | | + * | ... | Function call stack + * | | + * +-----+ + * low + * + */ + + /* Save FP and LR registers to stay align with ARM64 AAPCS */ + emit(A64_PUSH(A64_FP, A64_LR, A64_SP), ctx); + /* Save callee-saved register */ emit(A64_PUSH(r6, r7, A64_SP), ctx); emit(A64_PUSH(r8, r9, A64_SP), ctx); if (ctx->tmp_used) emit(A64_PUSH(tmp1, tmp2, A64_SP), ctx); - /* Set up BPF stack */ - emit(A64_SUB_I(1, A64_SP, A64_SP, stack_size), ctx); - - /* Set up frame pointer */ + /* Set up BPF prog stack base register (x25) */ emit(A64_MOV(1, fp, A64_SP), ctx); + /* Set up function call stack */ + emit(A64_SUB_I(1, A64_SP, A64_SP, stack_size), ctx); + emit(A64_MOV(1, A64_FP, A64_SP), ctx); + /* Clear registers A and X */ emit_a64_mov_i64(ra, 0, ctx); emit_a64_mov_i64(rx, 0, ctx); @@ -196,8 +220,8 @@ static void build_epilogue(struct jit_ctx *ctx) emit(A64_POP(r8, r9, A64_SP), ctx); emit(A64_POP(r6, r7, A64_SP), ctx); - /* Restore frame pointer */ - emit(A64_MOV(1, fp, A64_SP), ctx); + /* Restore FP/LR registers */ + emit(A64_POP(A64_FP, A64_LR, A64_SP), ctx); /* Set return value */ emit(A64_MOV(1, A64_R(0), r0), ctx); -- 2.0.2

[V3 PATCH] arm64: remove redundant FRAME_POINTER kconfig option and force to select it

by Yang Shi

FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine it in arch/arm64/Kconfig.debug. Actually, the one defined in arm64 directory is never used. This adds a dependency on DEBUG_KERNEL for building with frame pointers. ARM64 depends on frame pointer to get correct stack backtrace and need FRAME_POINTER kconfig option enabled all the time. However, currect implementation makes it could be disabled, so force it to be selected by ARM64.

[PATCH V2 0/5] PM / OPP: opp-supported-hw and <prop>-name bindings

by Viresh Kumar

Hi Rafael, All the bindings are Reviewed by Stephen now and Rob didn't had a problem with them (though he didn't Ack them separately yet) :) The first patch enables us to select only a subset of OPPs from the bigger table, based on what version of the hardware we are running on. The second one enables us to select slightly different values for multiple properties, based on what kind of hardware they are running on. The third one removes an (unused) binding, which is replaced by the second patch with a better solution. The fourth patch is based on what Stephen suggested (and then reviewed) in the earlier series, and the 5th one updates the existing users of these bindings for it. Viresh Kumar (5): PM / OPP: Add "opp-supported-hw" binding PM / OPP: Add {opp-microvolt|opp-microamp|turbo-mode|opp-suspend}-<name> binding PM / OPP: Remove 'operating-points-names' binding PM / OPP: Rename OPP nodes as opp@<opp-hz> ARM: dts: exynos4412: Rename OPP nodes as opp@<opp-hz> Documentation/devicetree/bindings/opp/opp.txt | 143 +++++++++++++++++++------- arch/arm/boot/dts/exynos4412.dtsi | 28 ++--- 2 files changed, 118 insertions(+), 53 deletions(-) -- 2.6.2.198.g614a2ac
