2020-11-11net: phy: aquantia: do not return an error on clearing pending IRQsIoana Ciornei
The referenced commit added in .config_intr() the part of code which upon configuration of the IRQ state it also clears up any pending IRQ. If there were actually pending IRQs, a read on the IRQ status register will return something non zero. This should not result in the callback returning an error. Fix this by returning an error only when the result of the phy_read_mmd() is negative.

2020-11-11net: ipa: change a warning to debugAlex Elder
When we determine from hardware what the size of IPA memory is we compare it against what we learned about it from DT. If DT defines a region that's larger than actual memory, we use the smaller actual size and issue a warning. If DT defines a smaller region than actual memory we issue a warning too. But in this case the difference is harmless; so rather than issuing a warning, just provide a debug message instead. Reorder these checks so the one that matters more is done first.

2020-11-11net: ipa: don't break build on large transaction sizeAlex Elder
The following call in ipa_validate_build() is erroneous: BUILD_BUG_ON(sizeof(struct gsi_trans) > 128); The fact is, it is not a bug for the size of a GSI transaction to be bigger than 128 bytes. The correct operation of the driver is not dependent on the size of this structure. The only consequence of the transaction being large is that the amount of memory required is larger. The problem this was trying to flag is that a *slight* increase in the size of this structure will have a disproportionate effect on the amount of memory used. E.g. if the structure grew to 132 bytes the memory requirement for the transaction arrays would be about double. With various debugging build flags enabled, the size grows to 160 bytes. But there's no reason to treat that as a build-time bug. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-11-10net: dsa: fix unintended sign extension on a u16 left shiftColin Ian King
The left shift of u16 variable high is promoted to the type int and then sign extended to a 64 bit u64 value. If the top bit of high is set then the upper 32 bits of the result end up being set by the sign extension. Fix this by explicitly casting the value in high to a u64 before left shifting by 16 places. Also, remove the initialisation of variable value to 0 at the start of each loop iteration as the value is never read and hence the assignment it is redundant.

Most GSI general errors are unrecoverable without a full reset. Despite that, we want to receive these errors so we can at least report what happened before whatever undefined behavior ensues. Explicitly disable all such interrupts in gsi_irq_setup(), then enable those we want in gsi_irq_enable().

It is possible for other execution environments (EEs, like the modem) to request changes to local (AP) channel or event ring state. We do not support this feature.

2020-11-07net: ipa: only enable GSI IEOB IRQs when neededAlex Elder
A GSI channel must be started in order to use it to perform a transfer data (or command) transaction. And the only time we'll see an IEOB interrupt is if we send a transaction to a started channel. Therefore we do not need to have the IEOB interrupt type enabled until at least one channel has been started. And once the last started channel has been stopped, we can disable the IEOB interrupt type again. We already enable the IEOB interrupt for a particular channel only when it is started. Extend that by having the IEOB interrupt *type* be enabled only when at least one channel is in STARTED state. Disallow all channels from triggering the IEOB interrupt in gsi_irq_setup(). We only enable an channel's interrupt when needed, so there is no longer any need to zero the channel mask in gsi_irq_disable().

2020-11-07net: ipa: only enable generic command completion IRQ when neededAlex Elder
The completion of a generic EE GSI command is signaled by a global interrupt of type GP_INT1. The only other used type for a global interrupt is a hardware error report. First, disallow all global interrupt types in gsi_irq_setup(). We want to know about hardware errors, so re-enable the interrupt type in gsi_irq_enable(), to allow hardware errors to be reported. Disable that interrupt type again in gsi_irq_disable(). We only issue generic EE commands one at a time, and there's no reason to keep the completion interrupt enabled when no generic EE command is pending. We furthermore have no need to enable the GP_INT2 or GP_INT3 interrupt types (which aren't used). The change in gsi_irq_enable() makes GSI_CNTXT_GLOB_IRQ_ALL unused, so get rid of it. Have gsi_generic_command() enable the GP_INT1 interrupt type (in addition to the ERROR_INT type) only while a generic command is pending.

2020-11-07net: ipa: only enable GSI event control IRQs when neededAlex Elder
A GSI event ring causes an event control interrupt to fire whenever its state changes (between NOT_ALLOCATED and ALLOCATED). No event ring should ever change state except when we request it to. Currently, we permit *all* events rings to generate event control interrupts--even those that are never used. And we enable event control interrupts essentially at all times, from setup to teardown. Instead, only enable the event control interrupt type for the duration of an event ring command, and when doing so, only allow the event ring being operated upon to cause the interrupt to fire. Disallow all event rings from issuing the event control interrupt in gsi_irq_setup(). Because an event ring's interrupt is only enabled when needed, there is no longer any need to zero the event channel mask in gsi_irq_disable().

2020-11-07net: x25_asy: Delete the x25_asy driverXie He
This driver transports LAPB (X.25 link layer) frames over TTY links. I can safely say that this driver has no actual user because it was not working at all until: commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work") The code in its current state still has problems: 1. The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and in x25_asy_write_wakeup (when sending) are not protected by locks against x25_asy_change_mtu's changing of the transmitting/receiving buffers. Also, all "netif_running" checks in this driver are not protected by locks against the ndo_stop function. 2. The driver stops all TTY read/write when the netif is down. I think this is not right because this may cause the last outgoing frame before the netif goes down to be incompletely transmitted, and the first incoming frame after the netif goes up to be incompletely received. And there may also be other problems. I was planning to fix these problems but after recent discussions about deleting other old networking code, I think we may just delete this driver, too.

2020-11-06Revert ibmvnic merge do_change_param_reset into do_resetDany Madden
This reverts commit 16b5f5ce351f8709a6b518cc3cbf240c378305bf where it restructures do_reset. There are patches being tested that would require major rework if this is committed first. We will resend this after the other patches have been applied.

Pull drm fixes from Dave Airlie: "It's Friday here so that means another installment of drm fixes to distract you from the counting process. Changes all over the place, the amdgpu changes contain support for a new GPU that is close to current one already in the tree (Green Sardine) so it shouldn't have much side effects. Otherwise imx has a few cleanup patches and fixes, amdgpu and i915 have around the usual smattering of fixes, fonts got constified, and vc4/panfrost has some minor fixes. All in all a fairly regular rc3. We have an outstanding nouveau regression, but the author is looking into the fix, so should be here next week. I now return you to counting. fonts: - constify font structures. MAINTAINERS: - Fix path for amdgpu power management amdgpu: - Add support for more navi1x SKUs - Fix for suspend on CI dGPUs - VCN DPG fix for Picasso - Sienna Cichlid fixes - Polaris DPM fix - Add support for Green Sardine amdkfd: - Fix an allocation failure check i915: - Fix set domain's cache coherency - Fixes around breadcrumbs - Fix encoder lookup during PSR atomic - Hold onto an explicit ref to i915_vma_work.pinned - gvt: HWSP reset handling fix - gvt: flush workaround - gvt: vGPU context pin/unpin - gvt: mmio cmd access fix for bxt/apl imx: - drop unused functions and callbacks - reuse imx_drm_encoder_parse_of - spinlock rework - memory leak fix - minor cleanups vc4: - resource cleanup fix panfrost: - madvise/shrinker fix" * tag 'drm-fixes-2020-11-06-1' of git://anongit.freedesktop.org/drm/drm: (55 commits) drm/amdgpu/display: remove DRM_AMD_DC_GREEN_SARDINE drm/amd/display: Add green_sardine support to DM drm/amd/display: Add green_sardine support to DC drm/amdgpu: enable vcn support for green_sardine (v2) drm/amdgpu: enable green_sardine_asd.bin loading (v2) drm/amdgpu/sdma: add sdma engine support for green_sardine (v2) drm/amdgpu: add gfx support for green_sardine (v2) drm/amdgpu: add soc15 common ip block support for green_sardine (v3) drm/amdgpu: add green_sardine support for gpu_info and ip block setting (v2) drm/amdgpu: add Green_Sardine APU flag drm/amdgpu: resolved ASD loading issue on sienna amdkfd: Check kvmalloc return before memcpy drm/amdgpu: update golden setting for sienna_cichlid amd/amdgpu: Disable VCN DPG mode for Picasso drm/amdgpu/swsmu: remove duplicate call to smu_set_default_dpm_table drm/i915: Hold onto an explicit ref to i915_vma_work.pinned drm/i915/gt: Flush xcs before tgl breadcrumbs drm/i915/gt: Expose more parameters for emitting writes into the ring drm/i915: Fix encoder lookup during PSR atomic check drm/i915/gt: Use the local HWSP offset during submission ...
